American National Standard for Acoustics - Measurement of Airborne Noise Emitted by Information Technology and Telecommunications Equipment - Part 2: Declaration of Noise Emission Levels.
美国声学国家标准.信息技术和电信设备发出的空气噪声的测量.第2部分:噪声发射水平的声明
This Standard specifies procedure and requirements of the verification of noise emission levels of
information technology and telecommunications equipment. Hitherto, a wide variety of methods have
been applied by individual manufacturers and users to satisfy particular equipment or application
needs. These diverse practices have, in many cases, made comparison of noise emission difficult.
This Standard unifies the procedure and requirements that make the declared noise emission levels
consistent for information technology and telecommunications equipment.This Standard is technically identical to parts of ECMA-109 (2010).
