Electrostatics -- Part 4-7: Standard test methods for specific applications – Ionization (IEC 61340-4-7:2017) (english version)
This part of IEC 61340 contains test methods and procedures for the assessment and selection of devices and systems for the ionization of air (ionizers). This document presents measurement techniques for determining offset voltage (ion balance) and time for voltage reduction (charge neutralization) for ionizers under specified conditions. This document does not cover measurements of electromagnetic interference (EMI) or the use of ionizers in connection with weapons, flammable or explosive objects or electrically detonated explosive devices.
