The following list gives some measures for double-sampling plans. The formula for each measure is given in the section describing the corresponding function.

• the probability of acceptance, , calculated with the PROBACC2 function

• the average sample number, ASN, calculated with the ASN2 function

• the average outgoing quality, AOQ, calculated with the AOQ2 function

• the average total inspection, ATI, calculated with the ATI2 function
