Do I have to blast my test specimen for cleaning it as my production is before plating it? Blasting the surface does affect the specimens ability to resist embrittlement and can result in error. Conduct the test by loading the samples to the calculated value and then holding the load for the amount of time specified in ASTM F or until the material yields.

VAR also meets the requirements in AMS and could be used as an alternative to air melt steel by the steel suppliers because AMS does not specify a melting practice.
