High-voltage test techniques for low-voltage equipment - Part 1: Definitions, test and procedure requirements
1 Scope
1.1 Subject content
This standard specifies the general requirements regarding test procedures and test objects, methods for generation and measurement of test voltages and currents, test procedures, methods for the assessment of test results, criteria for acceptance, and terms related to the test.
1.2 Application scope
This standard is applicable to the following tests on equipment having a rated voltage of not more than 1kV a.c, or 1.5kV d.c.:
a) dielectric tests with direct voltage;
b) dielectric tests with alternating voltage;
c) dielectric tests with impulse voltage;
d) tests with impulse current;
e) tests with combinations of the above.
