ESD: IEC 61000-4-2, MIL-STD-461 CS118, ISO 10605, et. al.
Several standards cover ESD testing in similar ways. This article gives an overview plus places to look for additional guidance and alternate discharge models.
ANSI C63.16: “Guide for Electrostatic Discharge Test Methodologies and Acceptance Criteria for Electronic Equipment”
This is a guidance document for ESD testing that helps the users of IEC 61000-4-2 (as well as ISO 10605 and MIL-STD-461 CS118)
MIL-STD-461: “Requirements for the Control of Electromagnetic Interference Characteristics of Subsystems and Equipment”
MIL-STD-461 is one of the core EMC standards, having evolved with military applications since WWII. It is widely used in the aerospace and defense sectors.
