This standard establishes the minimum requirements for materials testing laboratories (MTL) accredited by NADCAP. The following test methods and processes for metallic material systems are covered in this standard. a Chemical b Mechanical c Metallography and Microhardness d Hardness e Corrosion and Oxidation f Mech. Test Specimen Preparation g Differential Thermal Analysis h Heat Treat of Specimens i Other Non-Conventional/Engineering Tests j Fastener Testing Slower quench rates tend to produce lower tensile strength in Quench + Temper and Solution + Age alloys. For example, properties of water quenched specimen material may not adequately represent oil or air quenched parts. (And in most cases, specimen material has less effective thickness -- hence a naturally faster cooling rate -- than the parts represented even when the same type quench is used.)
