Sampling procedures for inspection by variables - Double sampling schemes indexed by acceptance quality limit (AQL) for lot-by-lot inspection1 Scope This part of ISO 3951 specifies an acceptance sampling system of double sampling schemes for inspection by variables for percent nonconforming. It is indexed in terms of the acceptance quality limit (AQL). The objectives of the methods laid down in this part of ISO 3951 are to ensure that lots of acceptable quality have a high probability of acceptance and that the probability of non accepting inferior lots is as high as practicable. This is
