Challenge of standards for emerging NDT methods.

摘要

The preparation of standards for emerging NDT methods may sound paradoxical with the rapid changes normally associated with new and emerging technology. However, consensus documentation of terminology and basic methods of performing tests of NDT equipment can do much to aid in the emergence and acceptance of such technology. Subcommittee E7.10 was established to serve as an ''umbrella'' group and home for standards activities on emerging or other technology that has not yet grown sufficiently large to justify an independent subcommittee. Current activities include sections on thermoelectric sorting of metals, optical holography, and infrared methods. In addition, there are task groups on NDT reliability and methods for metal verification, identification, and sorting.
