The American Society for Testing and Materials' (ASTM) program for developing nondestructive testing (NDT) standards resides primarily in Committee E-7 on Nondestructive Testing. To meet this responsibility, Committee E-7 is subdivided functionally into subcommittees representing most of the major methods of NDT. The many activities necessary to the development of standard documentation that are conducted include industry surveys to determine interest, needs, and practices, performance of experimental studies through extensive cooperative studies in both government and private organizations, document preparation, and interlaboratory testing. Committee E-7 is responsive to requests from other ASTM committees as well as other standard organizations (for example, American Society of Mechanical Engineers). Although benefits to industry have accrued in the consensus standards, significant improvements are needed to provide more relevant, quantitative, reproducible results.
