    1. NDE in the ASME BPV Code -Trends and Developments in Industrial Diagnostics

    2. Council of Codes & Standards Section V, Subcommittee V Volumetric Methods Surface Examination methods General Requirements/Personnel Qualifications and Inquiries

    3. Ultrasonic techniques TOFD Flaw Sizing Electromagnetic Techniques ACFM Techniques Remote Field Eddy Current Radiographic Techniques Filmless Radiography

    4. Time-of-Flight Flaw Sizing (Moles, 2004A)

    5. TOFD Flaw Sizing Presented to the technical world in 1970’s. Limited computer capacity slowed the adoption of the technique. Cowfer and Hedden (1991) compared effectiveness of TOFD to amplitude down techniques. ASME Code Case 2235 approved 1996 and 2001. “Standard Practice for Use of the Time-of-Flight Diffraction Technique,” being considered as mandatory for Sec. V Appendix III of Article 4.

    6.

    7. Remote Field Eddy Current (Bray and Stanley, 1997)

    8. Alternating Current Field Measurement (ACFM) Work continues on developing the requirements for ACFM in Section V as new Article 15. Remote Field Eddy Current Subcommittee V approved Remote Field Testing Requirements into Section V as new Article 17. Magnetic Flux Leakage Requirements in Section V will be moved from Appendix III Article 7 to new Article 16.

    10. Sec. V, Appendix VIII approved by RT working group committee allows use of phosphorous plates in lieu of conventional film sheets. Code Case 2476 when included in the next Addendum in 2005 will allow using either phosphorous sheets or film. Sec. XI is following a similar path.

    11. ASME C&S Committees are staffed by volunteer engineers.
