Annotation of standard text ČSN EN 9138 (310431):

This European standard establishes requirements when implementing statistical product acceptance methods to meet defined risk requirements. This standard also establishes the minimum content required to be covered in an organization´s documented procedures that govern their application of statistical product acceptance methods.
These general requirements and documented procedures apply the requirements of the EN 9100/EN 9110/EN 9120 quality management system standards, in addition to establishing requirements for retrievability, safety/critical characteristics, and quality parameters that protect the customer.
This standard is applicable when invoked in a purchasing contract or specification, contractual document, customer agreement, or adopted by the organization. The purchase contract/agreement may or may not identify the appropriate EN 9138 clause(s) to be applied by the organization. All statistical methods of product acceptance require the use of Clause 4 and Clause 5.
To accept product produced:
- by individual lots, see Clause 6;
- under switching rules, see Clause 7;
- under process controls, see Clause 8; and
- by continuous sampling or special case methods, see Clause 9
