scope:

This International Standard describes a procedure for the determination of statistics in order to estimate the quality capability/performance of product and process characteristics. The process results of these quality characteristics are categorized into eight possible distribution types. Calculation formulae for the statistical measures are placed with every distribution. The statistical methods described in this part of this International Standard only relate to continuous quality characteristics. They are applicable to processes in any industrial or economical sector. NOTE - This method is usually applied in case of a great number of serial process results, but it can also be used for small series (a small number of process results).
