This technical bulletin addresses how measurement accuracy and uncertainty can be accounted for when making statements of conformity to specified requirements (In/Out tolerances or Pass/Fail decisions.) In particular, this technical bulletin explores one simple rule called the simple acceptance and refjection decision rule, which is the most commonly used decision rule in measurement practice. The technical basis for this document is the American national standard (ANSI standard) ASME B89.7.3.1-2001 Guidelines for Decision Rules, along with other historical documents.
