BS ISO 21747:2006
Statistical methods. Process performance and capability statistics for measured quality characteristics


BS ISO 21747:2006 describes a procedure for the determination of statistics in order to estimate the quality capability of product and process characteristics. The process results of these quality characteristics are tabularized into eight possible distribution types. Calculation formulae for the statistical values are placed with every distribution. These statistics relate to continuous quality characteristics exclusively.

This International Standard is applicable to processes in any industrial or economical sector.
