IEEE ANSI C63.24-2021 pdf download – American National Standard— Recommended Practice for In Situ RF Immunity Evaluation of Electronic Devices and Systems.
An important function of this recommended practice is to specify a consistent test protocol to allow results to be obtained and compared within and across other similar installations. To facilitate comparison between organizations, it is important that the recommendations herein are followed, deviations are kept to a minimum, documentation is thorough, and the testing is performed as consistently as possible. Policies and procedures for mitigation of electromagnetic interference (EMI), including use or restriction of specific RF transceivers within specific areas, should be based on objective information, including that obtained by the use of this test method. With regard to purchase evaluation, confirming that devices conform to electromagnetic compatibility (EMC) standards through laboratory type-testing can provide some information. This recommended practice can be used to supplement that information with an evaluation of the actual installed equipment which is subject to a composite EM environment not readily constructed at a test laboratory. The intent of this recommended practice is to provide an evaluation method using available portable transmitters that does not require laboratory testing. It also does not set a recommended minimum level of immunity and instead provides guidance on best practices for mitigation of interference. 1.3 Word usage The word shall indicates mandatory requirements strictly to be followed in order to conform to the standard and from which no deviation is permitted (shall equals is required to). 4, 5 The word should indicates that among several possibilities one is recommended as particularly suitable, without mentioning or excluding others; or that a certain course of action is preferred but not necessarily required (should equals is recommended that). The word may is used to indicate a course of action permissible within the limits of the standard (may equals is permitted to).
