Testimonials

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.

We are very happy with the service and co-operation we get here. It's a two-way thing. Improvements? No improvements to suggest really, we get just what we need.

Of all the Test Houses we use we get the best progress, best technicians and best accounts dept from 3C Test, also the best coffee.

We test quite frequently, when a colleague first visited he was very impressed with James going through everything with him, so we always use 3C Test. We are very pleased with the way we have been treated, staff always helpful. You have a really good crowd here, nice friendly atmosphere!

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.

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.
