IEC 61000-4-5-2017 pdf free.Electromagnetic compatility (EMC) – Part 4-5: Testing and mea surement techniques一Surge immunity test.
The object of this standard is to establish a common reference for evaluating the immunity of electrical and electronic equipment when subjected to surges. The test method documented in this part of IEC 61000 describes a consistent method to assess the immunity of an equipment or system against a defined phenomenon.
NOTE As described in IEC Guide 107. this is a basic EMC publication for use by product committees of the IEC. As also stated in Guide 107, the IEC product committees are responsible for determining whether this immunity test standard is applied or not, and if applied, they are responsible for determining the appropriate test levels and performance criteria. TC 77 and its sub-committees are prepared to co-operate with product committees in the evaluation of the value of particular immunity test levels for their products.
This standard defines:
— a range of test levels;
— test equipment;
— test setups;
— test procedures.
The task of the described laboratory test is to find the reaction of the equipment under test (EUT) under specified operational conditions to surge voltages caused by switching and lightning effects.
It is not intended to test the capability of the EUT’s insulation to withstand high-voltage stress. Direct injections of lightning currents, i.e. direct lightning strikes, are not considered in this standard.

3 Terms, definitions and abbreviations
3.1 Terms and definitions
For the purposes of this document, the terms and definitions given in lEG 60050 as well as the following apply.
3.1.1 avalanche device diode, gas tube arrestor, or other component that is designed to break down and conduct at a specified voltage
3.1.2 calibration set of operations which establishes, by reference to standards, the relationship which exists, under specified conditions, between an indication and a result of a measurement
Note 1 to entry: This term is based on the uncertainty approach.
Note 2 to entry: The relationship between the indications and the results of measurement can be expressed, in principle, by a calibration diagram.
