WG 4.0 – Worksurfaces

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

• STM4.1 document has been updated to current boilerplate including the addition of Annex A Verification Procedure of Measurement Set-up and revision to metal plate description.
• Reviewed TAS Comments - 69 Comments Received – 21 were labeled as Technical and these were reviewed and adjudicated. Which included all of the methods in the document updated to point to groundable point. In two locations the word “Note” was removed and the word “may” was changed to “shall”.
• Figures 3 & 4 were updated.

WG discussed and adjudicated WG member comments on ANSI/ESD WIP4.1. The document is almost ready for submission to TAS.

The WG continued the 5-year review of STM4.1, noting that updates to the drawing are still required. The committee identified the need to correct distance measurements within the document to match the drawings accurately. The group planned to incorporate new verification and calibration procedures into the document. After updating the document, it will be circulated among working group members for review.

The committee worked on the five-year review of ANSI/ESD STM4.1. The WG also reviewed a conveyor presentation that represented a snapshot of methods to measure resistance by various methods.

The WG had a discussion on drag chains regarding size, weight, length and the specifications within documents. The WG also continued working on the ESD TR4.0-02 – Conveyors Resistance Measurements.

The WG continued the review of the technical report on conveyor system measurements.

The WG completed the 5-year of ANSI/ESD STM4.1 “Worksurfaces” document. An update was made to the drawing during the last meeting; however, additional discussions and updates were made during the meeting. The drawing will be sent to the WG for a final review and then sent to TAS for review. The WG also discussed the worksurfaces section for ESD TR20.20. The WG briefly discussed the new TR on conveyors. A request was made for volunteers for a small writing team to move this forward.

The WG started the 5-year of STM4.1 “Worksurfaces” document.  During the meeting the approximately 50% of the document was reviewed, the remainder will be reviewed in subsequent conference calls or face-to-face meetings.

The WG completed the 5-year of ANSI/ESD STM4.1 “Worksurfaces” document. An update will be made to the drawing and sent out to the WG for a final review, once this is completed it will be sent to TAS.

The WG also started a review of the worksurfaces section for ESD TR20.20.

The WG continued working on a new technical report for Conveyors Presentations were given on lifting processes – ESD verification and process assessment and measurement of a conveyor.

The WG continued the development of a new TR on conveyors.
