Scope

The sampling plan and assessment procedures stipulated in this part of GB/T 2828 are used to assess whether the quality level of a certain population (batch or process, etc.) meets a certain claimed quality level. These sampling plans are designed so that the risk of rejecting a conforming population is 5%, and the risk of not rejecting a non-conforming population (see Clause 4) whose actual quality level is LQR times the claimed quality level is 10%. This part of GB/T 2828 provides sampling plans for four discrimination levels. Unlike the procedures in other parts of GB/T 2828, the procedures in this part cannot be used for batch acceptance sampling. This part of GB/T 2828 can be used for various forms of quality inspection. This part of GB/T 2828 is applicable to the situation where random samples composed of some unit products are allowed to be selected from the verification population. The sampling plan provided in this part of GB/T 2828 can be used (but not limited to) to inspect the following various products, for example: - final product; - parts and raw materials; - operation; - work in progress; - inventory; - maintenance operation ; — data or records; — management procedures.
