This document specifies procedures for measuring and reporting the noise emission of information technology and telecommunications equipment.
This document 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, ISO 9295 and ISO 11201.
The basic emission quantity is the A-weighted sound power level, which can be used for comparing equipment of the same type but from different manufacturers, or for comparing different equipment.
