4
Time-of-Flight Flaw Sizing (Moles, 2004A)
5

CS Activity in Ultrasonics

• TOFD Flaw Sizing
• Presented to the technical world in 1970s.
• 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.

CS Activities in Electromagnetics

• 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.

9

Filmless Radiography (H. Thiele, H. J. Friemel,
2000)
10

CS Activities in Filmless Radiography

• 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

Opportunities for Input into CS

• ASME CS Committees are staffed by volunteer
  engineers.

• CS Committees are seeking new members.

• Committee membership is open to non ASME
  members.

• NDE Engineering Division offers participation
  in NDE research and industry activities.
