Summary of discussions/activities/document reviews during the most recent WG meeting.

• Discussed/adjudicated comments of STDCOM vote on ANSI/ESD WIP12.1
  • Total 20 STDCOM comments (10 technical); all comments resolved/agreed on in WG
  • No vote resolved; reviewer agrees to the current solution
  • Technical changes in ANSI/ESD WIP12.1 will require STDCOM re-vote
• Topics identified for being considered in next revision of ANSI/ESD STM12.1 (discussion of topics will start after release of current ANSI/ESD WIP12.1):
  • Clarify the need for resistance measurements of all components of a chair, particularly the footrest, etc.
  • Add drag chain measurement discussion – addresses potential issues for several ESD control items
  • Consider adding floor creepers and mobile area platforms for personnel and other “seating objects”
  • Discussion for charge generation on chairs during movement – does the resistance measurement correlate with charge dissipation and generation?

WG discussed and adjudicated comments from the TAS review of ESD WIP12.1. The document is ready to be sent back to Operations for preparation for the next steps. Topics were identified to be addressed in the next revision of ANSI/ESD STM12.1, requiring significant technical work of WG.

The WG discussed and decided on the comments of the WG review of ANSI/ESD WIP12.1. The Manufacturing Task Team will discuss the verification of the metrology chain in the Annex.

The WG reconvened for a 5-year review of ANSI/ESD STM12.1. The document was reviewed and discussions were had on particular section. Agreed on changes of document, including changes discussed in Manufacturing Task Team.
