IEC 60060-2:2025 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 60060-2:2025 is applicable to complete measuring systems and to their components, used for the measurement of high voltages during laboratory and factory tests with direct voltage, alternating voltage and lightning and switching impulse voltages and combined and composite voltages as specified in IEC 60060-1. For measurements during on-site tests, see IEC 60060-3. The limits on uncertainties of measurements stated in this document apply to test levels stated in IEC 60071-1. The principles of this document apply also to higher levels but the uncertainty can be greater. This document: • defines the terms used; • describes methods to estimate the uncertainties of high-voltage measurements; • states the requirements that apply to measuring systems; • describes the methods for approving a measuring system and checking its components; • describes the procedures by which the user demonstrates that a measuring system meets the requirements of this document, including the limits set for the uncertainty of measurement. This fourth edition cancels and replaces the third edition published in 2010. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) The general layout and text has been updated and improved to make the standard easier to use. b) This document has been revised to align it with the fourth edition of IEC 60060-1. c) The treatment of measurement uncertainty estimation has been expanded. d) This document is now applicable to measuring systems used in testing at all standard insulation levels specified in IEC 60071-1. e) The measurement uncertainty requirement for the front time of the standard lighting impulse voltage has been changed from 10 % to 15 %, for testing at all standard insulation levels specified in IEC 60071-1. f) The parameter "time-to-peak" of the switching impulse defined in the third edition of IEC 60060-1:2010 has been replaced by "front time" in the fourth edition of IEC 60060-1. Necessary changes have been made in this document to accommodate this change in IEC 60060-1. g) Clause 10, Measurement of combined voltages and Clause 11, Measurement of composite voltages have been added. h) Clause B.1 has been significantly revised to align more closely with the provisions of Clause 5, including using the same nomenclature.
