Information technology equipment – Radio disturbance characteristics – Limits and methods of measurement

CISPR 22 (EN55022) has been replaced by CISPR 32 (EN55032)

A Joint Australian/New Zealand Standard prepared by the Joint Technical Committee TE-003, Electromagnetic Interference, which incorporates the Special International Committee on Radio Interference (CISPR).

The standard applies to information technology equipment (ITE) as defined in section 3.1.

Procedures are given in AS/NZS CISPR 22 for the measurement of the levels of spurious signals generated by the information technology equipment (ITE) and limits are specified for the frequency range 9 kHz to 400 GHz for both Class A and Class B equipment. No measurements need be performed at frequencies where no limits are specified.

The intention of this publication is to establish uniform requirements for the radio disturbance level of the equipment contained in the scope, to fix limits of disturbance, to describe methods of measurement and to standardize operating conditions and interpretation of results.

Information technology equipment (ITE), as would be tested for AS/NZS CISPR 22, includes computer hardware and software, operating systems, web-based information and applications, telephones and other telecommunications products, video equipment and multimedia products, information kiosks, and office products such as photocopiers and fax machines.

To deal with the problem of electromagnetic interference to radio communications, the Australian Communications Authority (ACA) and the Radio Spectrum Management Group (RSM) of the New Zealand Ministry of Economic Development have introduced the trans-Tasman electromagnetic compatibility (EMC) regulatory arrangements.

The trans-Tasman EMC arrangements consist of a set of technical standards and common regulatory processes for products supplied to the Australian and New Zealand markets.

The AS/NZS CISPR 22 EMC regulations apply to suppliers of a wide range of electrical and electronic products in Australia and New Zealand.
