IEC 61340-4-7 Ed. 1.0 en:2010

IEC 61340-4-7:2010(E) provides test methods and procedures for evaluating and selecting air ionization equipment and systems (ionizers). This standard establishes measurement techniques, under specified conditions, to determine offset voltage (ion balance) and discharge (charge neutralization) time for ionizers. This standard does not include measurements of electromagnetic interference (EMI), or uses of ionizers in connection with ordnance, flammables, explosive items or electrically initiated explosive devices.
