1. Scope 1.1 This guide provides sampling methods for determining how many fasteners to include in a random sample in order to determine the acceptability of a given lot of fasteners. 1.2 This guide is for mechanical properties, physical properties, coating requirements, and other quality requirements specified in the standards of ASTM Committee F-16. Dimensional and thread criteria sampling plans are the responsibility of ASME Committee B18. Therefore, unless otherwise specified in this guide, dimensional and thread fit sampling shall be in accordance with ANSI/ASME B18.18.3M. 1.3 This guide provides for two sampling plans: one designated the "detection process," as described in 3.1.3, and one designated the "prevention process," as described in 3.1.9.
