GB/T 16306-2008 Re-inspection and re-test procedures for assessment of declared quality levels
Basic Information
Scope
This standard specifies the evaluation procedures for the reinspection and retesting of product quality claims. The reinspection in this standard only applies to inspection lots composed of discrete individuals, not to bulk materials. The retesting in this standard applies to situations where the errors of the test results of the sample products conform to or approximately conform to a normal distribution. When expressing the quality level of the inspection lot in terms of the percentage of non-conforming products, the total number of inspection lots N should be greater than 250, and the ratio of the total number of inspection lots to the sample size should be greater than 10, that is, N/n > 10. When the total number of inspection lots does not exceed 250, or the ratio of the total number of inspection lots to the sample size is not greater than 10, the sampling plan retrieved by this standard is approximate, and it should be used with caution. It can also be determined according to the method specified in GB/T 13264.
