Description / Abstract:
This part of ISO/IEC 11553 describes the requirements to deal
with noise hazards and specifies all the information necessary to
carry out efficiently and under standardized conditions the
determination, declaration and verification of airborne noise
emission from laser processing machines and hand-held laser
processing devices within the scope of ISO/IEC 11553-1 and ISO/IEC
11553-2. It specifies the safety requirements relating to noise
hazards. It specifies noise measurement methods, installation and
operating conditions to be used for the test, together with the
information to be supplied by manufacturers of such equipment.
This part of ISO/IEC 11553 applies to those laser processing
machines and hand-held laser processing devices included in the
scope of ISO/IEC 11553-1 and ISO/IEC 11553-2.
Noise emission characteristics include emission sound pressure
levels at work stations and the sound power level. Declared noise
emission values permit comparison of laser processing machines and
handheld laser processing devices on the market.
The use of this noise test code (see Annex A) ensures the
reproducibility of the determination of the characteristic noise
emission values within specific limits. These limits are determined
by the accuracy grade of the noise emission measuring method used.
Noise emission measurements specified by this part of ISO/IEC 11553
meet the requirements of an engineering method (accuracy grade
2).
