WG 2.0 – Garments

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

• Working on the 5-year review of STM2.1.

The group continued reviewing ANSI/ESD STM2.1 for 5-year updates.

The group reviewed ANSI/ESD STM2.1 for 5-year updates. Need to add an additional procedure for garments in the Groundable Garment category with knit cuffs and update photos/figures.

The WG reviewed STM2.1 for the 5-year review. Possible revisions include:

• There was a discussion on voltage leakage of cables.
• Developed measurement system verification procedure.
• Removed sections from ANNEX that had misinformation.
• Removed procedures that were compliance verification tests.
• Identifying required measurements for each garment level.

WG started the 5-year review of ANSI/ESD STM2.1 “Garments – Resistive Characterization”. Several concerns were raised and discussed, such as:

• The use of “periodic verification” and “compliance verification” in a qualification document.
• Photos of test set-ups show test leads contacting the garments.
• Use of garments with and without cuffs.
• Document requires significant revisions.

Completed review and update of the Garments section in ESD TR20.20.

The WG reviewed the garment section of ESD TR2020. Much work needs to be completed, which will be done in virtual meetings to complete the review. The WG also discussed the 5-year review of ANSI/ESD STM2.1 “Garments – Resistive Characterization”.

The WG reviewed comments on the Garment section of the ESD TR2020 to determine whether changes to this or other documents are required. The WG also discussed the 5-year review of ANSI/ESD STM2.1 “Garments – Resistive Characterization” document.

The WG discussed the 5-year review of STM2.1 “Garments – Resistive Characterization” document and decided that some changes are needed to the appendix to correct incorrect information. A drawing and recording chart for ESD coveralls will be added. These are mentioned in the body of the document but there is no chart for listing test points and recording them. Changes will be sent to WG before the end of July for review.

It was also noted that additional items such as bouffants, face coverings, hats, etc., will be considered for addition to the STM or to TR later.

WG discussed the 5-year review of STM2.1 “Garments – Resistive Characterization” document.  Discussion focused on whether any changes need to be made, such as adding full overall suit drawing and test locations in an appendix.       

It was noted also that the WG needs to review the garments section of the newly release of TR20.20.
