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 Testing b Mechanical Testing c Metallography and Microhardness d Hardness e Corrosion f Mechanical Testing Specimen Preparation g Differential Thermal Analysis h Heat Treating i X-Ray Diffraction 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. (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.)
