Lessons Learned - Distributor Conformance Certification
Year: 1991
Abstract: Description of Driving Event:
When a quick disconnect was checked for compatibility with hydrazine the "O" seal disintegrated. It was found to have been made of material other than the required Ethylene-Propylene Rubber (EPR) material. The distributor had provided a certificate of conformance traceable to a seal manufacturers lot number. Upon a request for the manufacturers certificate of conformance they could not provide traceability for 40 pieces of a lot of 500 seals. They provided traceability for 460 of the seals.
