IEC 61340-4-7-2017 静电--第4-7部分：对于特定用途的标准试验方法--电离 Electrostatics -- Part 4-7: Standard test methods for specific applications -- Ionization

This part of IEC 61340 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. CAUTION: Procedures and equipment described in this document can expose personnel to hazardous electrical and non-electrical conditions. Users of this document are responsible for selecting equipment that complies with applicable laws, regulatory codes and both external and internal policy. Users are cautioned that this document cannot replace or supersede any requirements for personnel safety.dition 2.0 2017-01 INTERNATIONAL STANDARD NORME INTERNATIONALE Electrostatics – Part 4-7: Standard test methods for specific applications – Ionization électrostatique – Partie 4-7: Méthodes d'essai normalisées pour des applications spécifiques – Ionisation IEC 61340-4-7:2017-01(en-fr) THIS PUBLICATION IS COPYRIGHT PROTECTED Copyright ？ 2017 IEC, Geneva, Switzerland All rights reserved.
