DIN ISO 8525:2013-01

This test standard describes, with reference to ISO 230-5, the mechanical and acoustical specifications necessary for a reproducible test method for the determination of airborne noise emitted by metal-cutting machines and related auxiliary equipment (from 230-5). The purpose of this International Standard is to facilitate the obtainment of comparable and reproducible test results on the noise emission of similar machines. The results of the tests can be used for comparison, acceptance, maintenance or any other purpose. This International Standard specifies, in particular, operating conditions for the measurement of noise emitted by metal cutting machines. Any cutting processes are excluded here. These operating conditions are strictly the same for the determination of both sound power levels and emission sound pressure levels at a workplace or other specified positions. The standard applies to all kinds of turning machines, including numerical control (NC) turning machines and turning centres as well as all kinds of milling machines, including NC milling machines and machining centres.
