Construction and selection of tightened–normal–tightened variables sampling scheme of type TNTVSS (n 1, n 2; k)

This paper provides tables for the construction and selection of tightened–normal–tightened variables sampling scheme of type TNTVSS (n1, n2; k). The method of designing the scheme indexed by (AQL, α) and (LQL, β) is indicated. The TNTVSS (nT , nN; k) is compared with conventional single sampling plans for variables and with TNT (n1, n2; c) scheme for attributes, and it is shown that the TNTVSS is more efficient.
