AbolishedSampling procedures for inspection by variables - Part 4: Procedures for assessment of declared quality levels for mean
计量抽样检验程序 第4部分:对均值的声称质量水平的评定程序
Application Summary AI generated
This standard specifies sampling procedures for assessing whether the mean quality level of a product or process meets a declared value, using variable measurement data. It is applied in manufacturing and service industries for quality control, particularly when verifying supplier claims about average product characteristics (e.g., average weight, strength, or purity) through statistical sampling. The standard is used in contexts like incoming inspection, process validation, or regulatory compliance where objective evidence of mean performance is required.
