Why was MIL-A-8625 renamed/up-issued?
Up until recently, MIL-A-8625 had not been updated since 2003, which itself was a small amendment. In that time various referenced documents had been updated. In 2020, there was controversy when an auditing organisation adopted an interpretation of the dimensional requirements provisions of the standard, which was at odds with industry practices. This led to the standard being updated by the US Naval Air Systems Command for the US DoD to clarify the ambiguities in the standard in favour of industry norms.
The standard was renamed to MIL-PRF-8625 in line with the modern naming conventions for US MIL standards. PRF identifies that it is a performance specification.
How can I get a copy of MIL-PRF-8625 F2?
