Standard Practice for Utilization of Test Data to Determine Conformance with Specifications
 N D3244

Annotation

This practice covers guidelines and statistical methodologies with which two parties, usually a supplier and a receiver, can compare and combine independently obtained test results to obtain an Assigned Test Value (ATV) for the purpose of resolving a product quality dispute.

This practice defines a technique for comparing an ATV with a specification limit.

This practice applies only to those test methods which specifically state that the repeatability and reproducibility values conform to the definitions herein.

The statistical principles and methodology outlined in this practice can also be used to obtain an ATV for specification conformance decision when multiple results are obtained for the same batch of product within a single laboratory. For this application, site precision (R’) as defined in Practice D6299 shall be used in lieu of test method published reproducibility (R).

Утвержденный технологический процесс для использования данных испытаний для определения соответствия со спецификациями

Эта практика покрывает инструкции и статистические методологии, с которыми две стороны, обычно поставщик и получатель, могут сравнить и объединить независимо полученные результаты испытаний для получения Assigned Test Value (ATV) в целях решения спора качества продуктов.
