THC 61C Background

• Started in 1997, request by Mrfs.
• Originally THC 59 - Changed name to THC 61C in
  02 to align with IEC
• Existing UL/CSA Bi-National Std
  UL-250/CSA-C22.2 (ANCE uses IEC)
• Mfrs. want tri-national, based on IEC

4
THC 61C Issues

• Continuity of roster
• 2 different Chairman due to ANFAD personnel
  changes
• 2 diff Sec., due to AHAM changes
• Several mfrs. roster changes
• ANCE staff changes
• CSA staff changes
• UL only continuity!

5
Lessons Learned

• Need roster continuity
• Pace driven by mfrs.
• Shouldve done 60335-1 first, to reduce national
  differences in part 2
• Mexico cannot directly reference IEC standards
  increases national differences
• CSA adopted IEC 2-24 verbatim in late 90s, and
  saw CANENA effort as step back, so withdrew, but
  mfrs. not ready for IEC stds without some
  national differences
• Took 2 years to get CSA back

6
Status of THC 61C Effort

• Out for final approval by each SDO
• Expected publication summer 05
• Based on IEC 6th edition
• 38 pages of National Differences
• Differences may be reduced after Part 1 is
  harmonized

7
Future Concerns

• Keeping tri-national std current with IEC
  amendments both Part 1 2 (new IEC amendments
  just came out)
• Effective date transition period when either
  the current binational or tri-national std can be
  used
• mfrs. liability risk of not using most stringent
  one
