scope:

This part of IEC 60 is applicable to complete Measuring Systems, and to their components, used for the measurement of high-voltages and currents during tests with direct voltage, alternating voltage, lightning and switching Impulse voltages and for tests with Impulse currents, or with combinations of them as specified in IEC 60-1.

The limits on measurement uncertainties stated in this International Standard apply to test levels states in IEC 71-1. The principles of this International Standard apply also to higher levels but the uncertainty may be greater.

This standard:

- defines the terms used,

- states the requirements which the Measuring Systems shall meet,

- describes the methods for approving a Measuring System and checking its components,

- describes the procedure by which the user will show that a Measuring System meets the requirements of this standard.
