What is Electromagnetic Compatibility Testing?

EMC Testing Service | EMC Bayswater

What is electromagnetic compatibility testing? Let us try and explain it! Most of the today’s electrical products and electronic equipment are subjected to electromagnetic compatibility testing.

Electromagnetic Compatibility Testing is commonly known as EMC testing. In Australia, this testing is compulsory for manufacturers of certain products. This testing is necessary to demonstrate that their products are compliant with EMC standards. And is essential to meet the mandated requirements for distribution to the market.

How is Electromagnetic Compatibility Testing performed

EMC Testing | EMC Bayswater

EMC testing should be conducted by an accredited testing facility. This EMC testing laboratory should be equipped with suitably calibrated EMC test equipment and facilities. Including the appropriate calibrated EMC test chambers.

The technical capability and resources to perform the test to the applicable EMC product standard.

The testing body can be a third-party testing facility or an in-house laboratory. It ideally would be an accredited testing facility. Usually accredited by the local testing accreditation authority for the region, ideally recognised in other countries.

In Australia, EMC testing facilities are usually accredited by the local Australian authority, which is the National Association of Testing Authorities (NATA). NATA accreditation is recognised by many other countries globally. This is usually through Mutual Recognition Agreements (MRA).

NATA is part of the International Laboratory Accreditation Cooperation (ILAC). ILAC  promotes the acceptance of test and calibration data around the world.

Importance of EMC Testing

Electromagnetic Compatibility Testing or EMC testing is mandatory for almost all products which have an electronic or electrical circuitry whether wired or wireless powered. This is to ensure that products can function satisfactorily in the environment which they are going to be used. Furthermore, so they do not cause interference to other products.

There is a huge benefit for manufacturers in testing their products. Especially during the entire development cycle. Associated delays and costly recalls of the products can be avoided. The earlier the products can be tested for EMC compliance during the development cycle the better. A failure in the test at the end of product development cycle can be extremely costly especially in the redesigning of the product.

What types and markets require EMC Testing

Compliance with the EMC testing is mandatory in almost all markets including the U.S., Europe and Australia, among many others. This test is required for manufacturers in various industries including:

  • Medical devices;
  • Consumer products;
  • Military equipment;
  • Industrial machinery;
  • Automotive;
  • Aerospace; and
  • Railway

To be able to avoid delays in the marketing of your products, you need to properly prepare for what is needed prior to the final EMC testing. You must also allocate enough time to book an available booking at the testing laboratory, sometimes the lead time can be weeks.

You must also allow a contingency plan if the product initially does not comply. Allow time for any re-work or modifications are required i.e. compliance engineering the product to meet the standards.

Preparation for EMC Testing

It’s imperative for manufacturers to prepare the EMC testing requirements prior to entering the EMC test chamber in order to achieve the best results. Here is a helpful guide in preparing for EMC testing.

Write a test plan

Before the testing is done, it is necessary to be able to define the process beforehand. Analysing the requirements and knowing the types of test that your product needs to undergo is imperative. You need to know whether your product is subjected to conducted and radiated emissions only. Or if you will also need the EMC immunity testing as well.

You will also need to know which ports will be tested, which levels or limits will be used and what the pass and fail criteria are. That is why writing a test plan is essential.

How to write a test plan? EMC Test plan template

If you have already undergone Electromagnetic Compatibility Testing before, then you will be able to create a test plan yourself. However, if it is your first time to have an EMC test conducted, you can contact your test lab and seek a professional EMC test plan to be prepared for your particular product. A good test plan must have the following:

  • Product name, model number and identification details;
  • Product description of device to be tested including its I/O configurations and peripherals;
  • Required standards and applicable tests that are listed in the standards;
  • Quantity of samples requiring testing;
  • Product power supply requirements, i.e. 115/230VAC, 50/60Hz, 12VDC, PoE etc;
  • Dimensions of the product/system and also the weight of the product/system;
  • Type of equipment is it table top or floor standing;
  • Transmitter information if a wireless radio module is incorporated or used;
  • The lowest and highest internal frequencies used within the product;
  • Ports table including cable types, quantities, terminations and cable lengths;
  • Operating modes of the product;
  • Operating mode of the product and configuration for emissions testing (worst case);
  • Product emissions limits i.e. Class A, Class B etc (if applicable);
  • Operating mode of the product and configuration for immunity testing (worst case);
  • Declaring the intended environment, such as Basic, Industrial or Controlled EM etc;
  • EUT cycle time to complete all operations and allow observation of any failures;
  • Customer specified performance criteria and ways to recognise monitor and report failures;
  • Test fixtures, special software and supporting equipment to correctly exercise the product;
  • Definition of failure;
  • Estimated set-up time of the physical configuration and support equipment/software;
  • Declaring any health and safety related issues such as hazardous materials etc;
  • Special needs such as power, software and cooling among others;

Getting the price and schedule

Once you have the test plan written, you can now get the pricing and scheduling from an accredited 3rd party EMC test lab such as EMC Bayswater. Prepare the software and hardware for testing. You need to inquire what the lab will supply. More often than not, you will need the following:

  • Equipment under test (EUT) and spares;
  • Test fixture (if required);
  • Connectors and cables;
  • EMI suppression supplies such as ferrites, copper tape;
  • Tool kit;
  • Equipment’s design

During the test, you will need a compliance engineer or someone who is familiar with the product to witness the testing process.

Preliminary testing or pre-compliance testing

Preliminary testing or pre-compliance testing is also necessary to avoid possible failures in the final testing. There are shortened versions of the various test methods that can be done to identify possible failures.

Before the final testing, design modifications can be made. The most common pre-test that can be done is the radiated emissions pre-test. This pre-scan determines failures and suggests possible design modifications to enhance the equipment so it performs better for other test methods when needed.

Preparation prior to testing

Additionally, possible delays can be avoided if you are well prepared before the testing. Hence, when preparing your software and hardware for testing, you need to take note of the following:

  • The product that has to be tested must have its peripheral equipment included which constitute the entire system;
  • Any optional or auxiliary equipment that may be required during the test. If your product has a USB port, include a USB peripheral that can be used for that port. If you don’t ship a product with USB peripheral, then you provide a typical unit. Ensure that unit is pre-compliant to avoid failure during the test;
  • If functional auxiliary equipment for a particular port is not possible, dummy loads that exercise a port to its fullest extent will often do;
  • A monitoring method. This is crucial for immunity testing since the lab needs to monitor the performance of your product. Clearly defining methods for which you would like your product to be monitored is helpful to EMC test labs;
  • Two or more alternative backup power supply units. This is helpful whenever there’s a failure in conducted emissions testing. Conducted emissions problems can often be alleviated by swapping an external power adapter with a better performing one. Having more adapters can also be useful when doing surge testing;
  • Cables that are needed when exercising your product to the fullest. They must be the right length.
  • A software/firmware test mode that is needed when exercising all communication interfaces, memory interfaces and all moving parts at the highest speed possible; and
  • Proper documentation needed by the test engineers. This is highly important because if test engineers don’t know how to set up or operate your product into the proper test mode, it could delay in the test schedule.

Taking A Photography Course – The Case For Improving Your Skills

Photography Course | Ethos CRS

Even in a time when the ability to take high-resolution photographs in digital format is literally at almost everyone’s fingertips due to the increased resolution and functionality of smartphone-based cameras there is still a need for people to hone their skills as a photographer by attending a photography course.

Composition and using light, as well as a myriad of other considerations means that exploring the potential of cameras of any type is not only fun but rewarding in a variety of other ways.

 

After all, photography provides many benefits.

Among these benefits is the fact that good photography provides timeless memories. In fact, a good photograph can confer a type of immortality to the subjects. Take a look at an old wedding album and if the photographs are of good quality they will transport you back to the occasion. Those subjects will, in a sense live forever.

Photographs document life’s journey. There is a saying that a picture is worth a thousand words. Good photography can document those milestones that we reach and that transforms us into the adults that we one day become. It can capture moments that would otherwise have been lost in the shifting currents of time. A photography course will allow the photographer to capture the essence of that particular moment.

 

One of the most rewarding things about taking up photography is that it is a fantastic stress reliever.

The sheer focus that is required to frame that perfect moment in time – with a perfect composition that captures the essence of the subject matter means that there is very little mind space available for other problems.

It is said that when we look back at the time that we truly reached adulthood it was the same time that we lost the ability to really imagine. However, photography can reignite the flame of that imagination. A great photographer is one who can harness their imagination, looking at different angles, seeing things in a new light and – in fact, looking beyond the simple image to the imagery and deeper meaning of the photograph.

There are many people who say that true happiness comes from working at something that you love. It becomes less of a task and more of an expression of passion. For those with a passion for photography, it is entirely possible to make it their life’s work. Looking around we can see examples of photography by those people who have turned their passion into a career. think of the advertising you see, think of those photo stock libraries on the Internet.

A commercial photography course can teach the aspirant commercial photographer about the best routes to take to success. However – it is the passion for photography that will determine just how fulfilling that success will be.

Photography Course | Ethos

There can be no better boost to one’s feelings of self-worth than to succeed in capturing that perfect moment.

It does not have to be a professional level photograph – even the very young can feel that boost in self-esteem when they take what is in their minds a fantastic photograph – and sharing that beauty with friends and loved ones can further enhance that feeling of self-esteem.

Some of the most beautiful photographs ever taken involve the natural world around us. One does not have to believe in a higher power – but the sheer magnificence of the world around us as captured through the lens cannot but enhance our spirituality and connection to the natural world – and the people around us.

 

Photography also gives us a new appreciation for things that might otherwise have escaped our notice.

 

Framing a photograph at once booths allow for unrivaled focus, but also ensures that the photographer begins to notice the components of each individual scene. The play of light and shadow, the importance of what is happening on the periphery of any shot. All of these open our eyes to the myriad of wonders that make up our world.

Taking a photography course will enhance every aspect of a photographers chosen pastime. It is immensely valuable and also opens up new experiences and new techniques that keep photography evergreen for those with a passion for the image.

Why Do You Need A Kayak Anchor Trolley?

Kayak Trolley | Boat Hoist

A kayak anchor trolley helps the fishermen or angler to easily adjust the tie-down location of the anchor on his vessel. You can easily pull the anchor up by letting the tie-down move toward the angler. The angler has total control of the process when anchoring in any type of water thanks to the kayak trolley. That is why you need to invest in a kayak anchor trolley without delay. It is much cheaper than you would have thought.

Here is why you need a kayak trolley for successful fishing trips in the long run.

The anchor trolley is a pulley system made with ropes in order to establish a quick tie-down location anywhere on the body of the kayak. The average angler will travel with a 3×3 1/2 pound anchor. The nature of a kayak is such that an angler requires easy access to everything in his vessel. That is where an anchor trolley comes in handy. It provides a very convenient way of setting and adjusting the position of the anchor to the best spot of the kayak. Here is how a kayak trolley works:

Kayak Trolley | Boat Hoist. First, you need to attach two eye loops to one side of the hull of the kayak. It should be roughly the length of the kayak.

. Then, a long rope should be fed through these two loops. Each end of the rope should be tied to a metal ring that connects the rope together. This should visually form a long and thin oval on the side of the hull of your kayak.

. The angler is in a position to slide the ring to either the stern or the bow. Anywhere he prefers the anchor line to be set. Next, clip the anchor line to the metal ring on the trolley using the clip that is attached to the anchor line. Now you can drop the anchor off the side of the hull. The angler could adjust the anchor line however he prefers.

There are many reasons to invest in an anchor trolley. In fact, the product is quite affordable compared to the benefits it offers. Whether you fish in a lake, pond, or any other type of current, there are times when you want to move from your spot. But when you are in the middle of the action, it is not the best time to shift to a different location. Tying the anchor off to a specific location on the kayak won’t work.

That is because of the size of the kayak and the direction that your current will carry you. The anchor trolley helps the angler control the location of the tie off – which helps optimize the position of your vessel. This type of flexibility is essential when you are fishing. That is why a kayak trolley is the best product for any fishermen on a kayak.

There are different types and brands of anchor trolley on the market. Most of these products are available for a price below $40. Although there are many products out there, all of them are not suitable for your kayak. Make sure to pick the right product that suits your vessel. YakGear’s Deluxe Kayak Anchor Trolley kit is one of the best kayak trolleys on the market today. But you will find a couple of good offerings on Amazon.

Make sure that you do the research properly when shopping for the best product on the market. Amazon is the best e-commerce store to purchase a quality kayak trolley because they are trustworthy and professional in their approach to marketing. You can reveal your credit card information without any worry since Amazon uses a secure payment gateway. That is why you should shop for the best anchor trolley on Amazon.

You can add more control to your vessel by installing a high-quality and affordable kayak anchor trolley. It provides a host of benefits that you won’t regret later on. Anchoring becomes much easier with the right anchor trolley. Make sure that you do the research when shopping for the right product that suits your kayak. The above read offers information on why you need a kayak trolley.            

How to Do Your Own Formal Makeup

Formal Makeup - Perth | AG Makeup

With the formal season fast approaching, you have two make up choices. You can have professional formal makeup done or you can apply it yourself. If you choose to have it done professionally, the cost can be relatively exorbitant, however, the results will be worth it when you see yourself in photos or on social media.

You can save money simply by doing formal makeup yourself. It is not impossible. The steps below will help you get professional-looking results. If Kate Middleton could do her own makeup for her royal wedding, then you can do yours for your prom, wedding or another special spring event.

When you choose to do it yourself, you have complete control over the finished look.

 

Choose your dress and your hairstyle first.

Once this is done, you can figure out where to start with your makeup. You can also decide if you should get a fake tan or not. You might choose to go natural and allow your true skin tone to shine. This choice will dictate what foundation tones you use for your makeup.

Brows can make the biggest difference in one’s appearance. Choose whether you will have your microblade, waxed or left natural for the big event. Next, decide whether you will highlight your eyes or your lips.

Some suggestions for this include choosing to accentuate your eyes with smokey tones or earth tones. These colors are classic and will not go out of style anytime soon. You will look beautiful in your photos for generations. If you accent your eyes, use a neutral or clear-gloss for your lips. If you choose to highlight your lips, choose colors that compliment your dress and your skin tone.

Why Hydro Excavation is The Best Solution for Removing Liquid Waste

Hydro Excavation | Pressure Works

Removing liquid waste is considered harmful to people or the environment. It may be in the form of a sludge or purely liquid such as laboratory wastes.Liquid waste mostly comes from restaurants, homes, cars, washing machines and factories. Waste may be in the form of prescribed waste, oily water, surfactants, septic tank waste, grease traps, wash waters, among others.

Some of the most dangerous wastes include formaldehyde, corrosive substances, quarantine waste, contaminated soil, and other chemical wastes. The problem is, some companies usually dump these wastes directly into rivers and other water bodies. This is extremely dangerous. Do not do it.Liquid waste has very high amounts of toxic compounds such as salts and metals. Therefore, if it is not properly disposed of, it may cause health issues including diseases and even deaths of both people and animals.

That’s why you need to dispose of waste properly so that it would not harm people and animal.

OPTIONS FOR PROPER DISPOSAL

Some of the more common options for liquid waste removal include:

Dewatering and Sedimentation

This is usually an option when dealing with non-hazardous waste. Dewatering involves extraction of water, leaving behind solid components. Then, sedimentation is used to remove solid contaminants.

dewatering

Incineration

Where the liquid waste is deemed dangerous, incineration can be used. The waste is heated at very high temperatures eliminating most solid components (scrap metal, slag, rock, tailings, hardened oils, etc).

Root zone

The root zone is most commonly used when dealing with liquid waste coming from homes. This includes kitchen waste and bath water.Such water can simply be treated for recycling purposes and then safely reintroduced to the environment.

Compositing

Lastly, when dealing with organic waste, liquid waste removal can be done by compositing. Industrial compost waste management technique can transform any solid sediment into organic fertilizer.

Hydro excavation (HX)

However, there is a more advanced technique which is even more effective especially in industrial setups. It’s called hydro-excavation.

 

WHAT IS HYDRO EXCAVATION?

The primary quality of hydro excavation is that it is environment-friendly, more so that it is a green innovative technology. Also known as vacuum excavation, hydro excavation Melbourne technology uses pressurised water to safely and surgically convert solid ground into mud that can then be sucked up by a powerful truck-mounted vacuum system.

Basically, it is a not-mechanical and non-destructive process that combines pressurised water and high flow of moving air to simultaneously excavate native soils in a controlled manner. Hydro excavation Melbourne allows for quick, clean, and precise extraction with minimal labour, less backfill, and little environmental impact compared to conventional digging methods.

BENEFITS OF HYDRO EXCAVATION

This technique is considered superior to existing methods because it results in:

Clean Cuts

Using the pressurised water stream, the water gun works like a surgeon’s knife. This helps to ensure clean cuts with minimal post-excavation restoration activities.Hydro excavators can also be remotely placed so that the large imprint of the equipment can be easily removed.

Less material removed

With hydro excavators, you don’t need to remove a lot of material. This is partly because of the clean cutting capability. And, with less material being removed, there is usually less backfill to deal with and thus less restoration work needed.

Greater safety

In most excavation activities involving buried utilities, injuries and even deaths have been reported. Yes, they are that dangerous.Hydro-excavation is a less risky way of exposing buried utilities. Workers can stay on the surface during excavation eliminating the risk of cave-ins and potential other disasters.

Minimal environmental impact

Hydro excavation lends itself to a very clean process. First, less material is removed meaning there is less disruption to the surrounding environment. And secondly, any debris is usually stored onboard eliminating any chances of harmful chemicals being swept into water bodies.There are several other benefits of the technology.

Hydro excavation | Pressure Works

APPLICATIONS OF HYDRO EXCAVATION

Hydro excavation can be used in multiple waste removal situations including:

Potholing

Exposing or excavating underground utilities using HX is called potholing or day-lighting. The non-mechanical, non-destructive characteristics of hydro excavation make it ideal for this process. Underground utilities can be exposed without risks inherent in traditional excavation processes.Potholing can also be used in digging holes for telephone poles, signposts, and fences among others.

Slot trenching

If you’re looking to dig narrow trenches for installation of pipes, cables, and other in-ground utilities, you can also call on a hydro excavation. Unlike traditional slot trenches that usually cause expensive damages, HX provides, clean, non-destructive cuts even on frozen surfaces.

Mass removal

Hydro excavation can also be used in large-scale exposure of underground utilities. The HX equipment can quickly and safely expose underground utilities, especially when dealing with unknown “potentially dangerous” utilities.

Cold weather removal

Working in cold weather has always been an issue. The frozen ground causes many challenges that most other excavation techniques may not be able to handle.But hydro excavation is different. With a truck-mounted water heater warming the water to 150 degrees, freezing at any depth is never a problem.Moreover, utilising heated water to penetrate frost is a much more environmentally safe solution than emission-producing methods such as coal or wood firing.

Debris removal

Hydro excavation can also be used for debris removal. Cleaning different structures with this non-destructive method is quick and easy and you don’t have to worry about destroying the surrounding area. Other applications here include catch basin cleaning, sludge removal, and cleaning up sills.

Remote digging

When there is need to repair fibre cables, telephone lines, water mains, or other in-ground utility lines, HX can be used to excavate the utilities. This is because HX equipment can work in tight spaces with minimal impact and little restoration requirements.

Summary

In a nutshell, hydro excavation is a valuable removal technique that can help you dispose of buried waste quickly, safely and cost-effectively.

Car Rental 101 – Top 10 Points To Consider For Narrowing Your Choices

Car Rental | 1300 Meteor Rentals

Because there are so many car rental companies out there offering more of the same,  being overwhelmed and unable to decide on where to rent a car is rather expected.  But it does NOT have to be that way. Below you will find the top things you need to consider when choosing car rental services.

First off, though, here is a rundown of the different vehicles you can rent. There are compact and cheap cars that are best for city driving for singles and couples. For out-of-town trips with family, there are vans and SUV’s. For all-purpose driving for no more than five people,  there are sedans to choose from.

Car Rentals | 1300 Meteor Rentals

Most car rentals offer a wide selection of cars and it is up to you to decide where you will rent the car you need. Just remember the following points before making a decision.

 

1. The price always varies

Even when they offer the same type of car, no two car rentals will charge the same price. They will differ according to the length of the hire, the season, and the day of the week. That said,  always make sure to compare the prices of at least three rental companies.

 

2. Brand new is always expensive

Brand new cars will always come at a premium price regardless of where you rent. You can rent an older car for half the price. But this depends on the situation, that is, if the occasion calls for the look and feel of a brand-new vehicle.

 

3. Your needs come first

IF you are travelling with a lot of luggage, make sure to check the car rental has the appropriate car to serve your needs.If you are travelling as a group, make sure to check there is a Kia Carnival you can rent.

 

4. Insurance is never bad

Although you are paying for protection for something that may never happen, insurance is never a bad idea and most companies already include it in their rates. Check how much you will be paying in insurance.

5. The kilometres matter

There are companies that offer two types of rates. One offers an unlimited number of kilometres while the other only requires you to pay the number of kilometres you travel after a certain limit. In most cases, the latter option is cheaper if you’re only travelling within the city for a limited period of time.

 

6. Drivers are an option

While some rentals are self-drive, there are those that offer drivers, some at no extra cost. Would you rather enjoy your ride? Go for the driver option.

 

7. The extra items matter

If you are travelling with children or if you have someone with special needs, you will want to rent a car from the company that offers extras like seat boosters and the like. Like the driver, there are rentals that offer extras for free or as an option.

8. Roadside assistance is a must-have

Make sure to only do business with a company that offers roadside assistance. Normally you won’t be charged for mechanical faults but may be charged for a dead battery or a flat tire.

9. Can you smoke?

While you can expect for smoking to be a no-no, there are rentals out there that allow it if you are willing to pay for the cleaning fee.

 

10. Full tank

It’s fairly standard among car rental companies to give you the keys to a car with a full tank. While we don’t expect for any rental to have a different policy on gasoline, it is always a good idea to check and verify.

The ten points we mentioned above are the main points you need to consider when choosing a car rental company. It’s always a good idea to get a quote on the rental prices. However, it is also equally important to check the terms and conditions.

To find a car rental, just type the name of the local area where you need a car and add the words “car rental”.  Make sure to get information from at least three car rental companies and compare them based on the points we mentioned above.
