6.1 .3.2. Compliance Verification Plan Guidance In addition to internal audits, external audits (Organization and supplier of ESDS items) should be performed to ensure compliance with planned requirements. Verifications should include routine checks of the Technical Requirements in the Plan. The frequency of verification checks should be based on the control item usage, its durability and associated risk of failure .
6.2. ESD CONTROL PROGRAM PLAN TECHNICAL REQUIREMENTS Table 1 identifies and describes key Technical Requirements used in the development of a Program and Plan. Note that for each Technical Requirement there are required or optional implementing processes or methods (shown with an “R” or “O” in Table 1 ) from which to fulfill each Technical Requirement. In a case where there is a required implementing process or method within the Technical Requirements, the implementing process or method shall be used. If there are additional optional elements, they may or may not be implemented in the Plan. If a Technical Requirement only contains optional elements, (shown with an “O”) then at least one of the options must be implemented by the Plan. The Plan shall include test methods, acceptance limits and periodic testing intervals. Area 1 shown on Table 1 is intended to designate permanent ESD controlled areas such as manufacturing, production or distribution facilities. Area 2 shown on Table 1 is intended to designate temporary ESD controlled areas such as field service or other remote locations that are not normally equipped as a Protected Area. Test methods used by the organization that differ from the test method or reference in Table 1 shall be documented. Additional guidance may be obtained in ESD ADV 2.0 ESD Association Advisory for the Protection of Electrostatic Discharge Susceptible Items – Handbook
6.2.1. Grounding / Bonding Systems
6.2.1 .1 . Grounding / Bonding Systems Requirements Grounding/Bonding Systems shall be used to ensure that ESDS items, personnel and any other conductors (e.g. mobile equipment) are at the same electrical potential. As a minimum, ESDS items, personnel and other related conductors shall be bonded or electrically interconnected.
