My question is does anyone know what test methods (ASTM; Navair; etc) are used for the following items: Angle blocks; squares; feeler gages; protractors; and steel rules. In the past we have referenced MIL-STD120 on our calibration certificates. Can we continue to use MIL-STD120 even though it has been obsoleted? Along the same line would it be ok to use Fed Spec GGG-G-17 for radius gages?

Any takers for this question??

I did find a test method for steel rule/scale (GIDEP C2006). Still looking for help on the others.
