This Malaysian Standard is applicable to the test equipment used for dielectric tests on low-voltage equipment. It covers tests with direct, alternating or impulse voltage, impulse current, and tests with a combination of impulse voltage and impulse current. Verification procedures necessary for ensuring that the dielectric tests comply with the voltage, or current, requirements stated in part 1 of this standard in shape and magnitude are stated. The test equipment comprises a voltage and/or current generator and a measuring system.
This standard covers test equipment in which the measuring system is protected against external interference and coupling by appropriate screening, for example a continuous conducting shield. Therefore, simple comparison tests are sufficient to ensure valid
results. Test equipment having measuring systems composed of non-screened components and/or connected by long leads is not covered in this standard. In this case guidance can be obtained from IEC 60-2
