Testimonials

Suggestions for Improvements? Nothing can be improved, you have been spot on with everything, excellent, and your engineer has tried everything he can to help us. Your service has been far and beyond what we had asked for.

I would like to thank you for your time yesterday, very much appreciated and I would like to say how impressed I was with your company structure and layout. Look forward to seeing you in the near future with some new products.

Thank you very much for arranging the tests at such short notice. We really appreciate your help. I would like specially to thank Matt and the team. He was very helpful during the test and kept me well informed with test progress.

Your facilities are excellent, and the engineers are very friendly, very helpful. I know you are not the cheapest but who wants a cheap test house that tells you your product has failed and throws it back at you, sometimes you cannot even speak to an engineer, just sales people. How you can judge a company is when you have problems and how they react, I am very impressed with the service and will certainly return.

Presentation is important, the grandeur and opulence and the fresh clear-cut feel of your building is superb. Along with the new facilities it is exactly what we wanted for our testing. We are testing to stringent spec and the automotive connection here is important to us! In the past we have built up a good relationship with 3C through e mails and quite complex negotiations regarding our requirements. I enjoy coming here.

Our testing went well it's good to interact with the Test Engineers and use their experience to aid the testing, it's nice to know we are not getting button pushers. It's also reassuring to know that if something unexpected happens you can rely on the advice you are given, we don't test enough to gain experience in EMC Testing, I have learned something each time I have been here to test.

               EMC Marine

Testing for equipment to be installed on board ships:

There are several EMC standards which cover marine equipment. These include EN 60533, Lloyds Register spec N°1 and the most commonly used standard IEC 945.

IEC 945 is a complete test standard for the marine environment taking into account the mechanical, electrical and environmental conditions as well as the EMC phenomena.

Sections 9 and 10 of IEC 945 includes the EMC requirements, that covers a wide frequency range due to the nature of the equipment found on board ships which is explained in annex C of the standard.

Section 9 covers the EMC emissions, which take into account the protection of the ships navigation and radio systems as well as the consideration that ships normally operate at sea and will not cause interference to land based radio communications.

Section 10 is the EMC immunity section, which is also tailor made to suit the marine environment. However, the standard adopts the IEC 1000-4-x test methods, setups and equipment for most of the tests but have extended frequency ranges to take into account the expected frequency ranges on board a ship.

Although IEC 945 and EN 60533 are comprehensive test specifications, in some cases the Lloyds Register Spec. N°1 is applicable for the ships underwriters, and may also be required. This is normally part of the contractual agreement when supplying equipment integral to a particular ship.

If you wish to test to any of these standards, it is always best to call for more specific requirements. The standards also take into account the location, purpose and how the instrument is to be installed on the ship.

 3C Test have added EN 60945:2002, SECTION 9 & 10 to our schedule enabling us to test Marine Navigation, Radionavigation, Marine instruments and safety.
