This document standardizes quality management system requirements for the aerospace industry. The establishment of common requirements for use at all levels of the supply chain by organizations around the world should result in improved quality and safety and decreased costs due to the elimination or reduction of organization-unique requirements and the resultant variation inherent in multiple expectations. Hygrade has been ISO approved since September of 1997 and AS9100:2001 approved since November of 2007.
Hygrade was initially approved by NADCAP in January of 2004 for Aerospace quality system (AC7004) and Chemical Processing (AC 7108). NADCAP stands for National Aerospace and Defense Contractors Accreditation Program, and is required by companies such as GE, Rolls Royce, Boeing, Bombardier, Pratt and Whitney, and Sikorsky aircraft. Hygrade is audited annually for compliance.
