IEC 61000-4-1-2006 pdf Electromagnetic compatibility (EMC) – Part 4-1: Testing and measurement techniques – Overview of IEC 61000-4 series

With regard to the variety of equipment and environmental conditions to be considered, it is difficult to indicate exact rules concerning the selection of tests. This selection is primarily the responsibility of the product committee concerned (based on their experience). In special cases, this can be fixed by agreement between the manufacturer and the user. In all cases, knowledge of the electromagnetic environment (the IEC 61000-2 series, especially IEC 61000-2-5) and awareness of the statistical aspects explained in IEC 61000-1-1 will be helpful.
Test according to IEC 61 000-4-2 (Electrostatic discharge immunity test) In general, the electrostatic discharge test is applicable to all equipment which is used in an environment where electrostatic discharges may occur. Direct and indirect discharges shall be considered. Exclusions may include equipment limited for use in ESD-controlled environmental conditions and non-electrical or electronic products.
IEC 61 000-4-7 (General guide on harmonics and interharmonics measurements and instrumentation, for power supply systems and equipment connected thereto) This technical report defines the measurement method of harmonics and interharmonics. It compares the characteristics of an analogue measuring equipment and of a digital measuring equipment. It provides also the accuracy awaited and the test set-up. It is applicable to voltage or current measurements in the d.c. frequency range up to 2 500 Hz, especially with regard to the emission requirements according to IEC 61 000-3-2, IEC 61 000-3-4, IEC 61 000-3-6, IEC 61 000-3-1 2 and IEC 61 000-4-30.
Test according to IEC 61 000-4-1 1 (Voltage dips, short interruptions and voltage variations immunity test) This document defines the test methods to evaluate the immunity of an equipment connected to the LV system, to voltage dips, short interruptions and voltage variations. This test is applicable to equipment with a rated input current of less than 1 6 A per phase, connected to a.c. mains. The standard describes also different levels of tests, four performance criteria, the operating condition when the equipment is tested and the test set- up. It is a basic standard which can be used as a tool for the product committees which are defining their own EMC immunity standard.
