Test code for machine tools — Part 5: Determination of the noise emission

1.1 General

This part of ISO 230 specifies methods for testing the noise of stationary floor-mounted machine tools and related

auxiliary equipment directly on the shop floor. The purpose of the measurements is to obtain noise-emission data

for machine tools.

The data obtained may be used for the purpose of declaration and verification of airborne noise emission from

machine tools as specified in ISO 4871, and also for the comparison of the performance of different units of a given

family of machine tools or equipment, under defined environmental conditions and standardized mounting and

operating conditions.

For the purposes of this part of ISO 230, "auxiliary equipment" means hydraulic power packs, chip conveyors,

coolant-oil mist extractors, heat exchangers, refrigerators, etc. Noise emitted by centrally operated auxiliary

equipment, connected to several machine tools, shall be considered as background noise.

General instructions are given for the installation and operation of the machine under test and for the choice of

microphone positions for the work station and for other specified positions. More detailed instructions can be found

in specific noise-test standards
