SAE AMS QQ SPECS

SAE AMS QQ SPECS

SAE AMS QQ SPECS

(OP)
I am getting thrown around in loops trying to find out what has superseded my list of specs. What is the difference between a QQ-A-### spec and an SAE AMA QQ-A-### spec with the same number designation? They have different revision letters and different superseding documents.

RE: SAE AMS QQ SPECS

QQ-A-### were standards issued and maintained by the United States Federal government.  There was a decision made to reduce this burden, and shift it to other entities whose core values encompass standardization, meaning Standards Development Organizations (SDO) like SAE International, ASTM International, etc.  In the cases where SAE took over a particular standard, SAE essentially appended their moniker to the beginning of the designation, thus changing QQ-A-250/11 into SAE AMS-QQ-A-250/11.  The SAE standard is the only valid document in this case, so reference it regarding validity/cancellation/supercession.

eBook - Mastering Tolerances for Machined Parts
When making CNC machined parts, mastering tolerances can be challenging. Are general tolerances good enough? When does it make sense to call out for tighter tolerances? Do you need a better understanding of fits, datums, or GD&T? Learn about these topics and more in Xometry's new e-book. Download Now
eBook – How to Choose the Correct Corrosion Testing Method
When designing a metal component, engineers have to consider how susceptible certain alloys are to corrosion in the final product’s operating environment. In a recent study by NACE (National Association of Corrosion Engineers), it was estimated that the direct and indirect costs of corrosion in the United States is approximately 6.2% of the GDP. In 2016, that cost exceeded $1 trillion dollars for the first time. Download Now
