scope:

This part 2 of the Standard defines the immunity requirements and test methods for equipment which must withstand electrostatic discharges, from operators directly, and to adjacent objects. Several severity levels are defined which relate to different environmental and installation conditions. These requirements are primarily developed for, and are applicable to, industrial-process measurement and control instrumentation. Most aspects of the standard, such as simulation parameters and test set-ups, may apply to other equipment, yet other aspects such as severity levels and performance criteria may not apply to other equipment. This document is intended to be identified as a basic EMC publication, in acccordance with IEC Guide 107. The object of this Part 2 is to establish a common reference for evaluating the performance of industrial-process measurement and control instrumentation when subjected to electrostatic discharges. In addition, it includes electrostatic discharges which may occur from personnel to objects near vital instrumentation.
