GB/T 16306-2008 in English

《GB/T 16306-2008声称质量水平复检与复验的评定程序》由TC21（全国统计方法应用标准化技术委员会）归口，主管部门为国家标准化管理委员会。
本标准规定了产品质量声称质量水平复检与复验的评定程序。
本标准中的复检仅适用于分立个体组成的核查总体,不适用于散料。本标准中的复验适用于样本产品的测试结果的误差服从或近似服从正态分布的情形。
当以不合格品百分数表示核查总体质量水平时,核查总体量�斡Υ笥�250且总体量与样本量之比应大于10,即��/��>10。当核查总体量不超过250,或总体量与样本量之比不大于10时,则由本标准检索出的抽样方案是近似的,应慎重使用,也可按GB/T13264中规定的方法确定抽样方案。

Scope

This standard specifies the evaluation procedures for the re-inspection and re-inspection of the quality level of product quality claims. The re-inspection in this standard is only applicable to the verification population composed of discrete individuals, not to bulk materials. The re-inspection in this standard is applicable to the situation where the error of the test result of the sample product obeys or approximately obeys the normal distribution. When the overall quality level of the inspection is represented by the percentage of non-conforming products, the overall inspection amount N should be greater than 250 and the ratio of the overall amount to the sample size should be greater than 10, that is, N/n>10. When the total number of checks does not exceed 250, or the ratio of the total size to the sample size is not greater than 10, the sampling plan retrieved from this standard is approximate and should be used with caution. The sampling method can also be determined according to the method specified in GB/T 13264 plan.
