- The ISO (International Organization for Standardization) acceptance sampling standards and their national versions are the most widely used statistical standards. ISO 2859 is a multi-part series of standards for attributes sampling.
ISO 3951 is a multi-part series of standards for variables sampling where the proportion nonconforming is determined as the probability of a normally distributed measurement falling outside a specification range.
ISO 2859 includes the process oriented attributes sampling standard 2859-1 and the isolated lot oriented standard 2859-2. ISO 3951 contains only the process oriented part, namely 3951-1 which is a descendent of the US military standard MIL-STD-414. For some times stakeholders particularly from the pharmaceutical and food industry have been requesting a variables sampling standard for isolated lot inpection. A draft for such a standard has recently been developed by the responsible technical committee TC 69 "Application of statistical methods'' at ISO. The talk outlines the new standard and explains the technical background and design principles, in particular technical details of matching sampling plans between the existing attributes sampling standard 2859-2 and the new variables sampling standard.
