BS EN 61340-4-7:2017 provides test methods and procedures for evaluating and selecting air ionization equipment and systems (ionizers).This document establishes measurement techniques, under specified conditions, to determine offset voltage (ion balance) and decay (charge neutralization) time for ionizers.This document does not include measurements of electromagnetic interference (EMI), or the use of ionizers in connection with ordnance, flammables, explosive items or electrically initiated explosive devices.As contained in this document, the test methods and test conditions can be used by manufacturers of ionizers to provide performance data describing their products. Users of ionizers are urged to modify the test methods and test conditions for their specific application in order to qualify ionizers for use, or to make periodic verifications of ionizer performance.The user will decide the extent of the data required for each application.Cross References:IEC TR 61340-5-2:2007IEC TR 61340-5-2:2007/COR1:2009CLC/TR 61340-5-2(IEC 61340-5-2:2007) ASESD TR20.20ANSI/ESD SP3.3ESD TR3.0-02-05All current amendments available at time of purchase are included with the purchase of this document.
