1.1 本规程提供了抽样方法，用于确定随机样本中应包括多少紧固件，以确定给定批次紧固件的可接受性或处置情况。 1.2 本规程适用于ASTM委员会F16标准中规定的机械性能、物理性能、性能性能、涂层要求和其他质量要求。尺寸和螺纹标准取样计划由ASME委员会B18负责。 1.3 本规程提供了两个采样计划:一个指定为“检测过程”，如术语中所述 F1789 ，其中一个被指定为“预防过程”，如术语中所述 F1789 . 1.4 本规程旨在用作制造商的最终检验计划，或用作购买者/用户的进货检验计划。它不适用于第三方资格测试。 1.5 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。 ====意义和用途====== 4.1 抽样应以随机方式进行选择，确保批次中的任何单位都有同等的机会被选中。采样不应通过从容器顶部或多容器批次中的一个容器中进行选择来进行本地化。 4.2 买方应了解供应商的质量保证体系。这可以通过审计供应商的质量体系（如果有合格的审计员）或通过第三方评估认证（如IATF提供的认证）来实现 16949，或ISO 9001.

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 Committee B18. 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. ====== Significance And Use ====== 4.1 Sampling shall be selected in a random manner, ensuring that any unit in the lot has an equal chance of being chosen. Sampling should not be localized by selections being taken from the top of a container or from only one container of multi-container lots. 4.2 The purchaser should be aware of the supplier's quality assurance system. This can be accomplished by auditing the supplier's quality system, if qualified auditors are available, or by third-party assessment certification, such as provided by IATF 16949, or ISO 9001.
