Cancelled and superseded AMS specs
Cancelled and superseded AMS specs
(OP)
If an AMS spec is cancelled, does that mean I should use the previous revision, or not use that spec at all? I understand that if a spec is superseded, I would need to use the superseding spec, but some specs are cancelled but not superseded.
Examples:
Spec: AMS QQ-P-35 (http://standards.sae.org/amsqqp35a)
Revision: A Status: Cancelled
Revision: Baseline Status: Issued
This spec has been superseded by AMS 2700 (which is up to REV D).
Spec: AMS QQ-A-225/8 (http://standards.sae.org/amsqqa225/8b)
Revision: B Status: Cancelled
Revision: A Status: Reaffirmed
Revision: Baseline Status: Issued
This spec has not been superseded by any other spec.

RE: Cancelled and superseded AMS specs
For this particular issue, I believe the desire is to switch to a general consensus standard like ASTM B 211 Standard Specification for Aluminum and Aluminum-Alloy Bar, Rod, and Wire.
