BS EN 61000-4-2:200961000-4-2 IEC:2008 7 ELECTROMAGNETIC COMPATIBILITY (EMC) Part 4-2: Testing and measurement techniques Electrostatic discharge immunity test 1 Scope This part of IEC 61000 relates to the immunity requirements and test methods for electrical and electronic equipment subjected to
39、static electricity discharges, from operators directly, and from personnel to adjacent objects. It additionally defines ranges of test levels which relate to different environmental and installation conditions and establishes test procedures. The object of this standard is to establish a common and
40、reproducible basis for evaluating the performance of electrical and electronic equipment when subjected to electrostatic discharges. In addition, it includes electrostatic discharges which may occur from personnel to objects near vital equipment. This standard defines: typical waveform of the discha
41、rge current; range of test levels; test equipment; test setup; test procedure; calibration procedure; measurement uncertainty. This standard gives specifications for test performed in “laboratories“ and “post-installation tests“ performed on equipment in the final installation. This standard does no
42、t intend to specify the tests to be applied to particular apparatus or systems. Its main aim is to give a general basic reference to all concerned product committees of the IEC. The product committees (or users and manufacturers of equipment) remain responsible for the appropriate choice of the test
43、s and the severity level to be applied to their equipment. In order not to impede the task of coordination and standardization, the product committees or users and manufacturers are strongly recommended to consider (in their future work or revision of old standards) the adoption of the relevant immu
44、nity tests specified in this standard. 2 Normative references The following referenced documents are indispensable for the application of this document.
