Either ANSI/ESD S20.20 or EN 61340-5-1. Recently, the two documents have been harmonized so there are few differences.

IEC 61340-5-1 has been designated an European Norm so EN 61340-5-1. Regardless, the standard can be purchased from http://webstore.iec.ch/webstore/webstore.nsf/Artnum_PK/38199

Both ANSI/ESD S20.20 and EN 61340-5-1 require a written ESD control plan that includes the technical requirements of the ESD protected area ESD control items used in the program (the user has the option of what items to require). Both documents require a written training plan and compliance verification plan.

Both state: “A compliance verification plan shall be established to ensure the organization's fulfillment of the requirements of the plan. Process monitoring (measurements) shall be conducted in accordance with a compliance verification plan that identifies the technical requirements to be verified, the measurement limits and the frequency at which those verifications must occur. The compliance verification plan must document the test methods used for process monitoring and measurements. If the organization uses test methods that differ from the standards referenced in this standard, the organization must be able to show that the results achieved correlate with the referenced standards. Compliance verification records shall be established and maintained to provide evidence of conformity to the technical requirements. The test equipment selected shall be capable of making the measurements defined in the compliance verification plan.”
