**** The review has now ended ****

Def Stan 00-056 Part 1 Issue 8 for review - PDF (621KB)

Def Stan 00-056 Part 2 Issue 6 for review - PDF (1.2MB)

These are Draft Documents for review and are not to be used as an agreed Defence Standard.

Details of the review process are available here: Def Stan 00-056 briefing pack - DOCX (2.3MB)

This review process has been delayed due to issues within the UK MoD and the new deadline for comments is 17 April 2023.

Note. The briefing pack contains several embedded items (Titles 1 to 8) that support the review process.  These need to be opened individually from within the briefing pack document.

Additional note: The drafts of Def Stan 00-056 Safety Management for Defence Systems are available for public comment. Comments at this stage will aid in finalising the draft; it would be particularly helpful to highlight the following: -

  • Does the new standard create any problems?
  • Are there any areas that require further interpretation?
  • Is it restrictive in any way?

The new drafts are potentially subject to change before publication, so should not be used in contracts at the moment. Once formally published, they should be used in new contracts, but will not normally apply automatically to existing contracts.

Comments should be returned to before 17 April 2023.

I am currently reviewing Pt 1 of the draft standard and happy to summarise key findings on completion. Currently, the main issues are:

1.Numerous uses of the term 'must' within guidance notes which probably should be clauses or reworded.

2. The definition of Accident has introduced damage to property/equipment, but the only other use of 'damage' is with regard to health and so is not captured in any clauses or notes.

3. The definition of Accident has also specified that injuries should be 7 days or longer, which is difficult to assess without either a 'crystal ball' or medical expertise.
