ASTM F1470-2018 規定機械特性和性能檢驗用緊固件抽樣的指南 Standard Practice for Fastener Sampling for Specified Mechanical Properties and Performance Inspection

1.1 This practice provides sampling methods for determining how many fasteners to include in a random sample in order to determine the acceptability or disposition of a given lot of fasteners. 1.2 This practice is for mechanical properties, physical properties, performance properties, coating requirements, and other quality requirements specified in the standards of ASTM Committee F16. Dimensional and thread criteria sampling plans are the responsibility of ASME Committees B18.1 and B18.18.2M-B18.18.6M. 1.3 This practice provides for two sampling plans: one designated the “detection process,” as described in Terminology F1789, and one designated the “prevention process,” as described in Terminology F1789. 1.4 This practice is intended to be used as either a Final Inspection Plan for manufacturers, or as a Receiving Inspection Plan for purchasers/users. It is not valid for third-party qualification testing. 1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
