Specifies limits for harmonic current emissions applicable to electrical and electronic equipment having an input current up to and including 16 A per phase, and intended to be connected to public low-voltage distribution systems. The tests according to this standard are type tests. Test conditions for particular equipment are given in annex C. For systems with nominal voltages less than 220 V (…
Electromagnetic compatibility (EMC) - Part 4-27: Testing and measurement techniques - Unbalance, imm...
Considers immunity tests for electric and/or electronic equipment (apparatus and system) in its electromagnetic environment. Only conducted phenomena are considered, including immunity tests for equipment connected to public and industrial networks. Establishes a reference for evaluating the immunity of electrical and electronic equipment when subjected to unbalanced power supply voltage. Applies…
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…
