8. FUTURE STANDARDIZATION.

a. Consistent and repeatable industry engineering practices would benefit the compliance with requirements for material control. Shared composite databases and specifications throughout industry would enhance the efficiency of material suppliers, end-users, and regulators. We are building on the current FAA/NASA effort to pursue standardization of these specifications with organizations, including MIL-HDBK-17, the SAE International AMS Committee P-17, and ASTM International.

b. The material contained in this document provides guidance for the current industry and is valid for the future standardization efforts in material control. Progress in standardization can be tracked at MIL-HDBK-17 meetings (or via the website of "www.mil17.org") as part of active FAA initiatives to work with industry to ensure safe and consistent use of composites.
