  • The WG continued discussions on industry test methods for triboelectrification testing for gloves.

  • The working group discussed establishing a limit for ESD glove qualification based on industry input and possible new technical report activities on other topics.

  • Discuss feedback on conducting Various Test Methods for WG15 TR “ESD Glove and Finger Cots” implementation that could cross over to TR53 “Compliance Verification of ESD Protective Equipment and Materials”.

    An Ad Hoc Team was formed, and an Ad Hoc Meeting (sidebar) will take place in Mid May 2022 to discuss this further.

  • The WG reviewed a new proposed TR “ESD Gloves and Finger Cots” Test Methods. Triboelectrification was also discussed as well as shielding of gloves versus CAFE resistance.

     

  • The committee discussed the reasons for using two-cylinder electrodes for compliance verification within the EPA:

    • Measures operators wearing gloves using two stainless steel cylinders that are cleaned with IPA 70%.
    • Affords measuring both types of gloves that are conductive or static dissipative.
    • Method is not a replacement when a wriststrap is worn on one hand, and the other hand holds the stainless steel cylinder.

    Two members are moving forward on investigating the breakdown voltage for ESD safe gloves.

    There was a long discussion on proposing limits for gloves in ANSI/ESD S20.20 using ANSI/ESD STM15.1. The WG discussed defining different guideline recommendations with various glove types. A survey will be conducted with predetermined questions to end users and glove suppliers to address why is there no glove resistance limits in ANSI/ESD S20.20.

  • A presentation on the Limits for Gloves was given. The WG reviewed the industry survey, which showed that it was overwhelmingly in favor of limits, with several additional comments on the need for charging limits. There was a lively discussion on the limits and the importance of them. Also, the importance of triboelectrification or charge generation to prevent CDM and other various test methods was discussed.

  • Agenda

    1. Factory Glove Testing Methods for compliance or periodic verification.

     

     2. Inducing Voltage onto Static Control Gloves to test gloves for CAFE resistance before High Voltage Discharge (HVD) and after HVD.

     

     3. Explore glove classification for use with the Space & Défense, Medical Device, Healthcare and for Class 0E ESDS Devices.

    ANSI/ESD STM15.1 no change until release

     

  • A presentation was given on various testing methods. A task team will begin working on compiling test methods for triboelectrification testing, resistance verification​, breakdown voltage​, decay​, and charge retention.

  • Summary of meeting activities: 

    The group reviewed industry acceptance of the newly released ANSI/ESD STM15.1-2019. A decision was made to table discussion on charge retention. There was also a review of several electrostatic decay testing methods currently being utilized in industry using a 1” x 1” charge plate, 3.25” x 3.25” charge plate and 6” x 6” charge plate to verify glove performance during audits and assessments along with using the CAFE fixture with a charge plate for decay measurements. WG15 efforts will focus on compliance verification not qualification testing for a future technical report incorporating such methods and more.

  • Summary of meeting activities:

    ANSI/ESD STM15.1 was published between meeting series. The working group discussed possible test methods and industry practices for inclusion in a new technical report. A presentation was given on a technical assessment to BMDS hardware due to personnel protective equipment.

  • Summary of meeting activities:

    The working group reviewed a brief history of the WG for new guests. Then a presentation was given on data collected for surface resistance testing of nitrile gloves in comparison to the current procedures in ANSI/ESD SP15.1. Also, bare finger CAFÉ’ testing using various resistance meters at both 10 and 100 volts was conducted. Reference to ANSI/ESD STM11.11, ANSI/ESD STM11.12, and ANSI/ESD STM11.13 will be added to the updated document. New data was collected from one of the round robin test labs and will be resubmitted to the statistics committee for review. The WG adjudicated TAS comments on the document and will resubmit for another TAS review.

     

  • Summary of meeting activities:

    A brief history of the WG was presented to attendees.
