  IEC method

  construction practice
• Differences in Infrastructure

• Submit proposals to the IEC to change
  requirements
• Work with National TAGs
• TAG chairman's on THSC
• Harmonize codes where practical
• Harmonized component standards

Issues

• THSC 61 (60335-1)
• No issues
• THSC 61D (60335-2-40)
• Performance based vs. Prescriptive requirements.
• IEC method vs. existing method of documenting
  requirements.
• Practical Application Guideline (PAG)
• Need more industry involvement

Lessons Learned

• What would be done differently?
• Do Part 1 first
• Tri-National effort from beginning of process
• Keep focus on the scope and mission statement
• Membership the same, but different
• Allow time for the process to work
• Review harmonization considerations every meeting
• Have Fun!
