It¹s clear that EMC is part of applying for the CE mark, but I guess the real question I was asking apparently none too skillfully is why would a CE mark be required for a piece of equipment slated for use on a military vehicle, and Brit as well?

In the case of this product it is only the EMC Directive that is applicable. For compliance with the EMC Directive an EMC assessment needs to be carried out and documented, normally against one or more of the EU EMC harmonised standards. As there is no product specific EMC harmonised standard for this type of system the Generic EMC Standards was used. The EMC Assessment is based on the Def Stan 59-411 EMC Test Results and using Gap Analysis to compare these to the Generic EMC Standards requirements. In some cases additional testing against the EMC harmonised standards may also be required. I believe that this standard practice for the CE Marking of Military equipment in the UK. I hope this answers your question.

Ken Javor Phone: (256) 650-5261 From: Philip Stevenson <[email protected]> Reply-To: Philip Stevenson <[email protected]> Date: Tue, 3 Aug 2021 15:20:57 +0000 To: <[email protected]> Subject: [PSES] Applicability of Conducted Immunity testing of Standalone Systems interconnection cabling Dear Listing Members Dear CE Marking Association We are currently carrying out an EMC Directive assessment of one of our Vehicle Mounted Military Systems against the Generic EMC Standards for Industrial Environments. It is a dc powered standalone Military System with no external Signal Port Input or Output connections. It does have one external DC Input Port whose sole purpose is for charging the system batteries when the system is not in service. The length of the system battery charging cable is < 3m. In normal operation this external DC Input Port is not used. The Vehicle Mounted Military System consists of a number of sub-systems connected via fully screened interconnection cabling some of which are longer than 3 metres but all are much less than 30 metres long. The interconnection cabling is in some cases a combination of both signal and dc power connections but there are also some solely signal cables and dc power cables as well. My question relates to whether the EN 61000-6-2 Signal and DC Power Ports Radio-Frequency Common Mode test requirements are applicable to the sub-system interconnection cabling whose length is greater than 3m or not? Noting as previously stated the system has no external cable connections in normal operation. I am aware that DC Power connections do not have any cable length exemptions but in a standalone system this would not be considered to be a ³DC Distribution Network². Your advice on this matter would be greatly appreciated.
