|Composite Material Guide Undergoes Extensive Revision
ASTM Committee D30 on Composite Materials has recently completed an extensive overhaul on its Standard Guide for Testing Automotive/Industrial Composite Materials. While the standard has retained its designation D 4762 the rest of the document has undergone a complete revision, including the title, which is now Standard Guide for Testing Polymer Matrix Composite Materials.
While the original version of D 4762, which was first approved in 1988, was limited to automotive/industrial composite materials, the revised version includes all advanced polymer matrix composites. In addition to broadening the scope, Committee D30 has modernized D 4762 by including the extensive advances in standards made since 1988. We essentially threw out the old one and started over, says Richard E. Fields, chair of D30 and senior staff research engineer, composite structures and materials, Lockheed Martin Missiles and Fire Control. Fields says that the remaining similarity between the old version of D 4762 and the new one is that the original intent was to create a guide to selection of standards for a given scope of material, and weve retained that intent.

Fields says that the revised D 4762 has been generating much interest since it is now basically a complete primer to all of the D30 standards related to polymer matrix composites, as well as a useful reference to related standards of other ASTM committees. This document effectively creates an annotated, abstracted index to all the testing-related ASTM standards for advanced composites, says Fields. Also, it will be a living document that changes continuously as the referenced ASTM standards change.
Fields is quick to point out that the revision of D 4762 was a success thanks to the combined work of all D30 subcommittees. It was a team effort that involved every D30 subcommittee and a large number of committee members.
