ISO 28593:2017 按属性验收取样规程.基于控制出厂质量信用原则的验收零取样系统

1.1 This International Standard specifies a system of single sampling schemes for lot-by-lot inspection by attributes. All the sampling plans of the present system are of accept-zero form, i.e. no lot is accepted if the sample from it contains one or more nonconforming items. The schemes depend on a suitablydefined average outgoing quality limit (AOQL), the value of which is chosen by the user; no restrictions are placed on the choice of the value of the AOQL or on the sizes of successive lots in the series. The methodology ensures that the overall average quality reaching the customer or market-place will not exceed the AOQL in the long run. 1.2 The schemes are intended to induce a supplier, through the economic and psychological pressure of lot non-acceptance and consequent loss of accumulated credit, to attempt to maintain a nonconformityfree process, while assuring, by means of the lowest practicable sample sizes, that the long-term percentage of nonconforming items delivered to the customer or market-place does not exceed the AOQL. This objective is achieved by a progressive reduction in the sample size in response to good quality history. 1.3 The schemes are designed to be applied to a series of lots from each supplier. The credit principle provides: a) automatic protection to the customer if a deterioration in quality is detected, by means of a total loss of accumulated credit and reversion to a relatively large sample size whenever a nonconforming item is found, and 100 % inspection of 1) the first lot if it is not accepted, or 2) any non-accepted lot that immediately follows a non-accepted lot; b) an incentive to reduce sampling costs (by means of a progressive reduction in required sample size) if consistently good quality is achieved. 1.4 a) This International Standard is designed for use under the following conditions: where the inspection procedure is to be applied to a series of lots of discrete items that are intended to be identical, and which are all supplied by one producer using one production process (If there are different producers or production processes, this International Standard is intended to be applied to each one separately.); b) where one or more quality characteristics of these products are taken into consideration, which must all be classifiable as either conforming or nonconforming; c) where the inspection error involved in classifying the state of a product's quality characteristic(s) is negligible; d) where inspection is non-destructive. This International Standard can be suitable for regulatory purposes, as control of the expected quality of items reaching the market-place is achieved with the smallest possible sample sizes, and long-term control of the realized, or actual quality level in the market-place is achieved with certainty, regardless of how long or short individual suppliers' series may be. This International Standard can be used by  1  suppliers/producers, buyers/consumers and regulatory agencies to provide control of the expected quality of the totality of accepted product of each type from each source.

Acceptance sampling procedures by attributes - Accept-zero sampling system based on credit principle for controlling outgoing quality

ISO 28594:2017 产品验收的组合接受零点抽样系统和过程控制规程

This International Standard provides a set of accept-zero sampling systems and procedures for planning and conducting inspections to assess quality and conformance to specified requirements. In addition, this International Standard provides requirements for alternative acceptance methods proposed by the supplier. Such alternative methods would be based upon establishing and implementing an internal prevention-based quality management system as a means of ensuring that all products conform to requirements specified by the contract and associated specifications and standards. This International Standard, when cited in contract, is applicable to the supplier and extends to subcontractors or vendors. The quality plans are to be applied as specified in the contract documents, and deliverables may be submitted for acceptance if the requirements of this International Standard have been met. Sampling systems and procedures in this International Standard are applicable, when appropriate, to assess conformance to requirements of the following: a) end items; c) operations or services; e) supplies in storage; b) components or basic materials; d) materials in process; f) maintenance operations; g) data or records; h) administrative procedures. NOTE Use of the word “product” throughout this International Standard also refers to services and other deliverables. The sampling systems and procedures of this International Standard are not intended for use with destructive tests or where product screening is not feasible or desirable. In such cases, the sampling systems to be used will be specified in the contract or product specifications.

ISO 7870-8:2017 控制图. 第8部分: 小批量生产和少量混合批次的制图技术

This document describes ways of applying regular variables control charts to short runs and small mixed batches where the sample size for monitoring is restricted to one. It provides a set of tools to facilitate the understanding of sources of variation in such processes so that the processes can be better managed. The charts described are process-focused rather than product-focused. The user can plot, monitor and control similar characteristics on different items, or different characteristics on an item, on a single control chart. NOTE 1 The terms short run and small batch size are not well defined. Here, short run and small batch size are taken to mean only a few items are manufactured before a different item is then produced. NOTE 2 For situations where the subgroup size is larger than one, other standards apply.
