1 Scope
This Standard specifies definitions of the terms used in this Standard, the requirements which the measuring systems shall meet, the methods for approving a measuring system and checking its components, and the procedure by which the user will show that a measuring system meets the requirements of this Standard.
This Standard 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.
