To support assessment of client’s product qualification compliance per ANSI/ESD S20.20-2021 Section 7.3, the ESD Association has compiled a summary of requirements that you may use.
The document is split by category (Personnel Grounding, EPA, and Packaging) and then by each control item – each entry contains the following information:
• Test Method
• Required Limits
• Quantity of Samples
• Type or Method & Quantity of Results
• Environmental Conditioning
Environmental Conditioning:
Many of the existing standard test methods require both Low and Moderate Humidity conditioning, most of these methods (except static shielding bags (STM11.31) which requires Moderate RH) will be moving towards requiring only Low Humidity conditioning. As mentioned in ANSI/ESD S20.20-2021, organizations may use their facility’s lowest annual humidity for qualification if the control item remains within the facility and they have objective evidence that qualification was done at the low point.
Prior Adoption:
ESD control items that were previously qualified before the adoption of ANSI/ESD S20.20–2021 do not need to be requalified. For example, if an organization has used and verified a worksurface prior to adopting ANSI/ESD S20.20-2021, their verification records may be used in place of qualification.
We hope this document is a benefit to you and your organization, please provide us with any feedback on this document as you use it in future audits.
