Description of Content

This Draft Uganda Standard covers the practice, 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.
