Foreword

GB/T 2828 "Sampling procedures for inspection" is divided into the following sections, the structure and its expected international standards and will replace the corresponding national standards Quasi is. --- Part 1. by acceptance quality limit (AQL) retrieval batch inspection sampling plan (ISO 2859-1.1999, IDT; instead of GB/T 2828-1987) --- Part 2. limited by limiting quality (LQ) for isolated lot inspection retrieved sampling programs (ISO 2859-2. 1985, NEQ; instead of GB/T 15239-1994) --- Part 3. skip-lot sampling procedures (ISO 2859-3.2005, IDT; instead of GB/T 13263-1991) --- Part 4. claiming that the level of quality assessment procedures (ISO 2859-4.2002, MOD; instead of GB/T 14437-1997 and GB 14162-1993) --- Part 5. by acceptance quality limit (AQL) retrieval batch sequential sampling inspection plan system (corresponding to ISO 2859-5.2005) --- Part 10. Sampling system description (corresponding to ISO 2859-10.2006) --- Part 11. Small claims overall level of quality assessment procedures (instead of GB/T 15482-1995) This section GB/T 2828 Part 11. This Part replaces GB/T 15482-1995 "Product Quality Supervision and a small overall count sampling procedures and sample forms." This section GB/T 15482-1995 compared with the change in technical content include. --- Will oversee the quality level (D0) to claim that the quality level (DQL); --- Will oversee the overall total to verification; --- Will not be judged by the number changed to limit the number of non-conforming product; --- Will oversee the overall verification can not be changed by the general failure, will oversee the sampling can be changed by verifiable; --- The sample sampling sampling qualified to meet the requirements; --- Increasing the quality level and actual claims compared with the level of quality determination is discussed; --- Increasing the re-examination, review and verification of the efficacy of sampling defined; --- Special emphasis in this section may be applied in addition to the final products, components and raw materials, but also can be used to operate in the product library Deposit products, maintenance operations, data or records management program; --- Adjust the individual sampling program; --- Added Appendix A. This part of the Annex A, Annex B normative Annex, Appendices C and D are informative appendices. This part is proposed by the China National Institute of Standardization.

Introduction

Applications GB/T 2828 of Part 11 is different from the GB/T 2828 Part 1, also from GB/T 2828 4th section. GB /system acceptance sampling procedure T 2828 Part 1 provisions apply to both parties (such as suppliers and consumers) Bilateral agreements between. The actual delivery of the product after the rules of acceptance sampling procedure is only used as a test sample batches inspection. Therefore, these process Order unclear involve any formal claim to the level of quality. Acceptance sampling, that the quality of the water can be received in batches and batches of unacceptable No clear boundaries between the flat. GB/T 2828.1 in the transfer rules and sampling plan designed to encourage suppliers of products Than the average of the selected quality level AQL good process. GB /Part 1 and Part 3 T 2828 program applies to acceptance sampling, but not for the review, audit verification of a nuclear Charles claimed the overall quality. The main reason is that, GB/T 2828 Part 1 and Part 3 is used to retrieve the acceptance quality limit, and only The actual acceptance sampling purposes related. GB/T 2828 Part 11 and GB/T 2828 Part 4 is to evaluate the overall quality level of verification whether the discrepancies Closing its declared quality levels; however, Part 4 GB/T 2828 for the verification of the overall situation of more than 250, it is because When, if at 250, and the ratio of the amount of sample quantities and verification of the overall total amount of more than 10, use of GB/T 2828.4 square sample retrieval Case, and when the verification of the overall total amount of not more than 250, this section should be used to retrieve the sampling plan. Sampling procedures for inspection specified in this section are for the regular review of the need to do sampling and developed. When the implementation of these When forms of inspection, the responsible departments have to consider the risk of making incorrect conclusions, and in the organization and implementation of assessment (or audit, or test) Considered this risk. This part of the design rules, so that when in fact the actual quality level of verification are consistent with the overall level of quality claims, sentenced overall verification The risk of failure is very small. If you also want to verify when the actual quality level does not meet the general quality level of claims, sentenced to verification by the wind The same risk is very small, there must be a larger sample size. To minimize the amount of sample, allowing the fact when the actual quality level does not meet the declared quality Horizontal, sentenced to verification by a slightly higher risk. The wording reflects the determination result to an imbalance wrong conclusions different risks. When judged by the results of sampling verification failed overall, there Great certainty that. "overall verification of the actual quality level is inferior to the declared quality level." When the sampling results of verification by the judge, it is recognized As. "this limited sample size, we found no actual verification of the overall level of quality worse than the declared quality level." Therefore, when the small sample size When, on the situation sentenced to verification by the responsible department pays validation checks overall pass responsibility.

1 Scope

GB/T 2828 This section provides for the assessment of a total (or batch process) whether the level of quality does not meet a certain level of quality claims Sampling of programs and assessment procedures. GB/T 2828 This section applies to verification from a random sample drawn from the population of some units of the product composition, the number of substandard goods to Small overall quality index counted once sampling. Quality checks can be used for various forms of non-acceptance sampling for the batch. GB/T 2828 sampling scheme provided in this section can be used for (but not limited to) the following test a variety of products, such as. ---Final product; --- Parts and raw materials; ---operating; --- In the article; --- Inventory; --- Maintenance operations; --- Data or records; --- Management procedures. This part of the unit product for the test is divided into qualified and unqualified products, the overall number of the verification of non-conforming products Situation.
