IEC 61300-1:2016 provides general information and guidance for the basic test and measurement procedures defined in the IEC 61300-2 and IEC 61300-3 series for interconnecting devices and passive components. This standard should be used in combination with the relevant specification which will define the tests to be used, the required degree of severity for each of them, their sequence, if relevant, and the permissible performance limits. In the event of conflict between this basic standard and the relevant specification, the latter will take precedence. This fourth edition cancels and replaces the third edition published in 2011. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: reconsideration of the terms and definitions; addition of Clause 4.
