DIN EN ISO 11553-3:2012-01

This part of ISO 11553 describes the requirements for 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 11553-1 and ISO 11553-2. It specifies the safety requirements relating to those 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 11553 applies to those laser processing machines and hand-held laser processing devices included in the scope of ISO 11553-1 and ISO 11553-2. Noise emission characteristics include emission sound pressure levels at work stations and where required the sound power level. Declared noise emission values permit comparison of laser processing machines and hand-held laser processing devices on the market. The use of this noise test code 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 measuring method used. Noise measurements specified by this part of ISO 11553 are carried out by the engineering method (accuracy grade 2).
