Title Acoustics - Measurement of airborne noise emitted by information technology and telecommunication equipment
Original title Acoustique - Mesurage du bruit aérien émis par les équipements liés aux technologies de l'information et aux télécommunications [in French]
Bibliographic information International Organization for Standardization (ISO), Case postale 56, 1211 Genève 20, Switzerland, 2nd ed., 1999. v, 61p. Illus. 7 ref.
Abstract This international standard specifies procedures for measuring and reporting the noise emission of information technology and telecommunication equipment. It is considered part of a "noise test code" for this type of equipment, and is based on basic noise emission standards ISO 3741, ISO 3744, ISO 3745 and ISO 11201 (see also CIS 97-636). The basic emission quantity is the A-weighted sound power level which may be induced for comparing equipment of the same type but from different manufacturers, or comparing different equipment. Replaces CIS 88-2055.
