Standard Practice for Sampling a Stream of Product by Attributes Indexed by AQL 通过AQL索引的属性对产品流进行抽样的标准实施规程
发布日期: 2023-01-01
1.1 本规程使用MIL-STD-105E作为根据验收质量限(AQL)对稳定批次进行抽样的基础,建立了批次或批次抽样计划和属性检验程序。 1.2 本规程提供了ASTM格式的MIL-STD-105E抽样计划,供ASTM委员会和其他机构使用。它承认MIL-STD-105E在ASTM支持的行业中的持续使用。MIL-STD-105E中的大部分原文保留在章节中 4 – 6. 这一做法。 1.3 本标准未规定单位制。 1.4 本标准并不旨在解决与其使用相关的所有安全问题(如有)。本标准的使用者有责任在使用前建立适当的安全、健康和环境实践,并确定监管限制的适用性。 1.5 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《国际标准、指南和建议制定原则决定》中确立的国际公认标准化原则制定的。 =====意义和用途====== 4.1 目的- 本出版物建立了按属性检验的批次或批次抽样计划和程序。本出版物不得被解释为取代或与任何合同要求相冲突。“接受”、“验收”、“可接受”等词语仅指承包商使用本标准中包含的抽样计划,并不意味着客户(原文中的“政府”)同意接受任何产品。 客户可接受性的确定应符合合同文件的规定。本标准中描述的抽样计划适用于0.01%或更高的AQL,因此不适用于质量水平在百万分之一范围内的应用。 4.2 应用程序- 本出版物中指定的抽样计划适用于但不限于以下检查:( 1. )最终项目( 2. )部件和原材料( 3. )操作或服务( 4. )加工中的材料( 5. )储存中的供应品( 6. )维护操作( 7. )数据或记录( 8. )行政程序。这些计划主要用于连续的一系列批次或批次。该计划也可用于检查孤立批次或批次,但在后一种情况下,用户应注意查阅运行特性曲线,以找到能够提供所需保护的计划(参见 6.11 ).
1.1 This practice establishes lot or batch sampling plans and procedures for inspection by attributes using MIL-STD-105E as a basis for sampling a steady stream of lots indexed by acceptance quality limit (AQL). 1.2 This practice provides the sampling plans of MIL-STD-105E in ASTM format for use by ASTM committees and others. It recognizes the continuing usage of MIL-STD-105E in industries supported by ASTM. Most of the original text in MIL-STD-105E is preserved in Sections 4 – 6 of this practice. 1.3 No system of units is specified in this standard. 1.4 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. 1.5 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 Purpose— This publication establishes lot or batch sampling plans and procedures for inspection by attributes. This publication shall not be interpreted to supersede or conflict with any contractual requirements. The words “accept,” “acceptance,” “acceptable,” etc, refer only to the contractor’s use of the sampling plans contained in this standard and do not imply an agreement by the customer (formerly “Government” in original text) to accept any product. Determination of acceptability by the customer shall be as described in contractual documents. The sampling plans described in this standard are applicable to AQL’s of 0.01 % or higher and are therefore not suitable for applications where quality levels in the range of parts per million levels can be realized. 4.2 Application— Sampling plans designated in this publication are applicable, but not limited, to inspection of the following: ( 1 ) end items, ( 2 ) components and raw materials, ( 3 ) operations or services, ( 4 ) materials in process, ( 5 ) supplies in storage, ( 6 ) maintenance operations, ( 7 ) data or records, ( 8 ) administrative procedures. These plans are intended primarily to be used for a continuing series of lots or batches. The plans may also be used for the inspection of isolated lots or batches, but, in this latter case, the user is cautioned to consult the operating characteristic curves to find a plan which will yield the desired protection (see 6.11 ).
