DIN EN 9103:2007-11

The document is primarily intended to apply to new parts, but can also be applied to parts currently in production. The document shall be applicable to all production processes that influence the variation of Key Characteristics. The variation control process begins with product definition, typically an engineering drawing or specification which identifies Key Characteristics and leads to a variation management program for those Key Characteristics. This process may also be used for Producer-identified Key Characteristics.
