The purpose of Defence Standard 61-5 Part 6 is to ensure electrical interoperability between military (ground) vehicular supplies and installed equipment requiring a DC supply for nominal 12V and 24V systems.
WEMEC staff have many years of unique experience and knowledge of Def Stan 61-5. This unique knowledge was gained by acting as the lead technical advisor supporting Dstl during the update between issue 5 and issue 6, provided key technical support to Dstl when writing issue 7 and by providing design, integration and test support to platform and equipment suppliers since 2005.
Def Stan 61-5 Part 6 Issue 7 was released in March 2020 and builds upon the design and test requirements which were introduced in Issue 6. The key elements of change are:

- The PCDR has been changed to a Power Control Plan and is now considered a living document and is required to be at specified levels of completeness for each program deign review i.e. PDR, CDR
- To aid MOD Accreditors, Unique Identifiers have been introduced for each requirement
- Each Unique Identifier has been given a priority, Mandatory and Priority 1
- Clarification for Bespoke Platforms design requirements and equipment
- Centralised Load Dump Suppression (CLDS) systems are mandatory for all platforms
- Design and test requirements for circuit protection devices
- Introduction of DET09.A Load Balance into Annex A
