Acoustics. Declared noise emission values of information technology and telecommunications equipment1 Scope This document is applicable to information technology and telecommunications equipment. It specifies: a) for a batch of equipment, the method for determining the following values: the declared mean A weighted sound power level, LWA,m; the declared mean A weighted emission sound pressure level, LpA,m; the statistical adder for verification, Kv; the statistical upper limit A weighted sound power level, LWA,c; b) how acoustical and product

vibrations

and procedures to evaluate conformity for checking the quality of steel strip sheath

in particular with the adiabatic compression test for oxygen regulators

The advantage of this test method is that the alignment procedure between a launch fibre and the OCB is not necessary
