Scope
This standard specifies sampling procedures and sampling plans for lot-by-lot inspection by attributes with acceptance quality limit (AQL) as the quality index. This standard is applicable to the inspection of continuous series of lots, and may also be used for the inspection of isolated lots, but subject to the restrictions specified in Clause 8.
本标准规定了以接收质量限(AQL)为质量指标的逐批检验的计数抽样检验程序及抽样计划。本标准适用于连续批的检验，也可用于孤立批的检验，但应遵守第8章规定的限制条件。

Manufacturers, quality inspection agencies, and supply chain managers use this standard to design sampling inspection plans that ensure product lot quality meets predetermined acceptance quality limits. It balances producer and consumer risks through statistical methods, making it a fundamental tool widely adopted in quality control.
制造业、质检机构及供应链管理者使用本标准来设计抽样检验方案，确保产品批次质量符合预定接收质量限。它通过统计方法平衡生产方与使用方的风险，是质量控制中广泛采用的基础工具。
AI Summary AI generated
This standard specifies lot-by-lot attribute sampling procedures based on acceptance quality limit (AQL), applicable to continuous series and isolated lots. Key content includes sampling scheme design, switching rules (normal, tightened, reduced), and AQL determination. It reduces inspection costs while controlling quality risks through statistical sampling, widely used in manufacturing and quality inspection.
本标准规定了基于接收质量限(AQL)的逐批计数抽样检验程序，适用于连续批及孤立批检验。核心内容包括抽样方案设计、转移规则（正常、加严、放宽）及AQL的确定方法。标准通过统计抽样降低检验成本，同时控制质量风险，广泛应用于制造业和质检领域。
Key Sentences extracted from text
接收质量限(AQL)是当一个连续系列批被提交验收抽样时，可允许的最差过程平均质量水平。
抽样方案由样本量字码和接收质量限(AQL)确定。
当检验批的样本中发现的不合格品数或不合格数小于或等于接收数时，接收该批；否则拒收。
转移规则包括正常检验、加严检验和放宽检验之间的转换。
对于孤立批的检验，应使用极限质量(LQ)检索的抽样方案。
Acceptance quality limit (AQL) is the worst process average quality level that is permissible when a continuous series of lots is submitted for acceptance sampling.
The sampling scheme is determined by the sample size code letter and the acceptance quality limit (AQL).
When the number of nonconforming items or nonconformities found in the sample from the lot is less than or equal to the acceptance number, the lot is accepted; otherwise, it is rejected.
Switching rules include transitions between normal inspection, tightened inspection, and reduced inspection.
For the inspection of isolated lots, sampling schemes indexed by limiting quality (LQ) should be used.
