This appears to be another case where the government lacks the expertise to write a requirement. No doubt some former sergeant who now works in a government Program Office cut and pasted a specification from another program. Every requirement must be contractually met. So if you want that clutch disc to work during and after a 6G turn or in a nuclear warfighting environment the contracting company must devise tests to prove the part meets the government's requirements.
There are always a few competent engineers on a Program but most are people unable to earn a living outside the government.
