Standard Terminology Relating to Methods of Mechanical Testing

SCOPE
1.1 This terminology covers the principal terms relating to methods of mechanical testing of solids. The general definitions are restricted and interpreted, when necessary, to make them particularly applicable and practicable for use in standards requiring or relating to mechanical tests. These definitions are published to encourage uniformity of terminology in product specifications.
1.2 Terms relating to fatigue and fracture testing are defined in Terminology E 1823.
