28、s. 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 a
29、nd 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 accordance with IECGuide107. The object of this Part 2 is to establish a commo
30、n 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. 2 Normative reference The follo
31、wing standard contains provisions which, through reference in this text, constitute provisions of this International Standard. At the time of publication, the edition indicated was valid. All standards are subject to revision, and parties to agreements based on this International Standard are encour
32、aged to investigate the possibility of applying the most recent edition of the standard indicated below. Members of IEC and ISO maintain registers of currently valid International Standards. IEC 50(161):1990, International Electrotechnical Vocabulary Chapter 161: Electromagnetic compatibility. 3 Gen
33、eral This part relates to equipment, systems, sub-systems and peripherals which may be involved in static electricity discharges owing to environmental and installation conditions, such as low relative humidity, use of low conductivity (artificial fibre) carpets, vinyl garments, etc. which may exist
34、 in all locations classified in standards relevant to industrial process measuring and control instrumentation (for more detailed information, see clauseA.1 of Annex A). The tests described in this Part 2 are considered to be a first step in the direction of commonly used tests for the qualitative e
35、valuation of the performance of all electronic equipment as referred to in clause1. NOTEFrom the technical point of view the precise term for this phenomenon would be “static electricity discharge”. However, the term “electrostatic discharge” (ESD) is widely used in the technical world and in techni
36、cal literature. Therefore, it has been decided to retain the term ESD in the title of this Part 2. 4 Definitions/Terminology For the purposes of this International Standard, the following definitions apply. 4.1 degradation (of performance) an undesired departure in the operational performance of any
37、 device, equipment or system from its intended performance IEV161-01-19 NOTEThe term “degradation” can apply to temporary or permanent failure. 4.2 electromagnetic compatibility (EMC) the ability of an equipment or system to function satisfactorily in its electromagnetic environment without introduc

All lower levels must be sat
45、isfied. Details concerning the various parameters which may influence the voltage level to which the human body may be charged are given in clauseA.2 of Annex A. AnnexA.4 also contains examples of the application of the severity levels related to environmental (installation) classes. Contact dischar
46、ge is the preferred test method. Air discharges shall be used where contact discharge cannot be applied. Voltages for each test method are given inTable 1.a andTable 1.b. The voltages shown are different for each method due to the differing methods of test. It is not intended to imply that the test
47、severity is equivalent between test methods. Further information is given in clausesA.3, A.4 andA.5 of Annex A.
