标准范围
ISO 28598的本部分为供应商、客户和/或第三方对同一批次进行连续独立检验提供了属性抽样程序和单一抽样计划。ISO 28598的这一部分涉及:-供应商检验（最终检验、供应商要求的产品认证）；-顾客检验（进货检验、监督、验收抽样）；-第三方检查。当只需要一次检查时，ISO 28598的本部分也适用。给出了单次抽样计划的目录，并按标准质量限值（NQL）编制索引。ISO 28598的本部分规定了以下取样程序:-成品；-组件和离散项目；-运营；-离散项目及其产生过程；-数据和记录。属性抽样程序用于检验单个批次或离散产品的连续系列批次。当给出标准质量限值（NQL）并以每100项不合格或不合格的百分比表示时，这些程序适用。ISO 28598的本部分提供了供应商、客户和第三方验收抽样程序的协调系统。它也适用于供应商在合同中单独或与客户达成协议，规定以NQL表示的批次质量标准的情况。在这两种情况下，它都提供了一种连贯的方法，用于将批次指定为满意或不满意的装运和拟议用途。
This part of ISO 28598 provides attributes sampling procedures and single sampling plans for successive independent inspections of the same lot conducted by the supplier, customer and/or a third party.This part of ISO 28598 addresses:- supplier inspection (final inspection, product certification upon supplier's request);- customer inspection (incoming inspection, surveillance, acceptance sampling);- third party inspection.This part of ISO 28598 may also be applicable when only one inspection is needed.A catalogue of single sampling plans is given, indexed by the normative quality limits (NQLs).This part of ISO 28598 provides sampling procedures for:- finished product;- components and discrete items;- operations;- discrete items and the processes that produce them;- data and records.Attributes sampling procedures are provided for inspection of an isolated lot or a continuing series of lots of a discrete product. These procedures are applicable when a normative quality limit (NQL) is given and expressed in terms of percent nonconforming or nonconformities per 100 items.This part of ISO 28598 provides a co-ordinated system of supplier, customer and third party acceptance sampling procedures. It is also applicable to the case where a supplier individually, or on agreement with a customer, in a contract, specifies a lot quality criterion expressed in terms of an NQL. In either case, it provides a coherent methodology for designating lots as satisfactory or unsatisfactory for shipment and proposed use.
