1.1 本规程建立了表格和程序，用于使用MIL-STD-1235B作为对AQL索引的稳定批次流进行抽样的基础，应用五种不同类型的连续抽样计划进行属性检验。 1.2 本规程提供了ASTM格式的MIL-STD-1235B抽样计划，供ASTM委员会和其他机构使用。它承认MIL-STD-1235B在ASTM支持的行业中继续使用。MIL-STD-1235B中的大部分原文保存在章节中 6 – 10 这种做法。 1.3 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.4 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）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》中确立的国际公认标准化原则制定的。 ====意义和用途====== 4.1 保留军用抽样标准的原因是，世界各地的许多组织仍在以其当前形式使用这些标准。MIL-STD-1235B自20世纪90年代中期起不再得到美国国防部的支持，现已绝版，但确实存在于公共领域。这种做法代表MIL的转换- STD-1235B符合ASTM支持的标准。 4.2 本规程提供了应用五种不同类型连续抽样计划进行属性检验的表格和程序。这些连续采样计划将在第节中讨论 6 – 10 每个章节包括以下信息: (1) 启动100 % 使用中的检查。 (2) 何时切换到抽样检查的要求。 (3) 保证返回100的条件 % 视察 (4) 如果需要，可以更改代码字母。 (5) 当检查检查员发现最初由筛选检查员发现符合要求的缺陷时，该怎么办，即筛选无效。 (6) 切换到100之前发现缺陷的情况 % 导致100个周期过长的检查 % 因此必须采取行动，即长时间的筛选。 4.2.1 部分 6. （MIL-STD-1235B第2节）描述了CSP-1采样计划的具体程序和应用——一种单级连续采样程序，提供了100个序列之间的交替 % 检验和抽样检验。 4.2.2 部分 7. （MIL-STD-1235B第3节）描述了CSP-F抽样计划的具体程序和应用——CSP-1计划的一个变体，即CSP-F计划适用于相对较短的产品运行，从而允许使用较小的清除数。 4.2.3 部分 8. （MIL-STD-1235B中的第4节）描述了CSP-2抽样计划的具体程序和应用——该计划是对CSP-1的修改 % 只有在规定数量的无缺陷单元将任何两个有缺陷的样本单元分开后，才能恢复检查。 4.2.4 部分 9 （MIL-STD-1235B第5节）描述了CSP-T抽样计划的具体程序和应用，这是一种多级连续抽样程序，用于在证明产品质量优良时降低抽样频率。 4.2.5 部分 10 （MIL-STD-1235B第6节）描述了CSP-V采样计划的具体程序和应用——一种替代CSP的单级连续采样程序- T因为这些计划规定在质量良好的情况下减少清除次数，在这种情况下，减少采样频率没有任何经济价值。

1.1 This practice establishes tables and procedures for applying five different types of continuous sampling plans for inspection by attributes using MIL-STD-1235B as a basis for sampling a steady stream of lots indexed by AQL. 1.2 This practice provides the sampling plans of MIL-STD-1235B in ASTM format for use by ASTM committees and others. It recognizes the continuing usage of MIL-STD-1235B in industries supported by ASTM. Most of the original text in MIL-STD-1235B is preserved in Sections 6 – 10 of this practice. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.4 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 The reason for preserving military sampling standards is that many organizations throughout the world still use these standards in their current form. MIL-STD-1235B is no longer supported by the U.S. Department of Defense as of the mid-1990s and is out of print, but does exist in the public domain. This practice represents a conversion of MIL-STD-1235B to an ASTM-supported standard. 4.2 This practice provides the tables and procedures for applying five different types of continuous sampling plans for inspection by attributes. These continuous sampling plans are discussed in Sections 6 – 10 of this practice and each section includes information on: (1) Initiation of 100 % inspection in use. (2) Requirements on when to switch to sampling inspection. (3) Conditions warranting a return to 100 % inspection. (4) When a change in Code Letter, if desired, can be made. (5) What to do when the checking inspector finds a defect that was originally found conforming by the screening inspector(s), that is, ineffective screening. (6) Situations where a defect is found before the switch to 100 % inspection causing excessive periods of 100 % inspection so action must be taken, that is, long periods of screening. 4.2.1 Section 6 (Section 2 in MIL-STD-1235B) describes specific procedures and applications of the CSP-1 sampling plans – a single-level continuous sampling procedure which provides for alternating between sequences of 100 % inspection and sampling inspection. 4.2.2 Section 7 (Section 3 in MIL-STD-1235B) describes specific procedures and applications of the CSP-F sampling plans – a variation of the CSP-1 plans in that CSP-F plans are applied to a relatively short run of product, thereby permitting smaller clearance numbers to be used. 4.2.3 Section 8 (Section 4 in MIL-STD-1235B) describes specific procedures and applications of the CSP-2 sampling plans – a modification of CSP-1 in that 100 % inspection resumes only after a prescribed number of defect-free units separate any two defective sample units. 4.2.4 Section 9 (Section 5 in MIL-STD-1235B) describes specific procedures and applications of the CSP-T sampling plans – a multi-level continuous sampling procedure which provides for reducing the sampling frequency upon demonstration of superior product quality. 4.2.5 Section 10 (Section 6 in MIL-STD-1235B) describes specific procedures and applications of the CSP-V sampling plans – a single-level continuous sampling procedure which is an alternative to CSP-T in that these plans provide for reducing the clearance number in good quality situations where reduction of sampling frequency has no economic merit.
