ASTM E 1462 Document Information:
Title
Standard Test Methods for Insulation Integrity and Ground Path Continuity of Photovoltaic Modules
ASTM International
Publication Date:
Oct 10, 2000
Scope:
These test methods cover procedures for (1) testing for current leakage between the electrical circuit of a photovoltaic module and its external components while a user-specified voltage is applied and (2) for testing for possible module insulation breakdown (dielectric voltage withstand test).
A procedure is described for measuring the insulation resistance between the electrical circuit of a photovoltaic module and its external components (insulation resistance test).
A procedure is provided for verifying that electrical continuity exists between the exposed external conductive surfaces of the module, such as the frame, structural members, or edge closures, and its grounding point (ground path continuity test).
This test method does not establish pass or fail levels. The determination of acceptable or unacceptable results is beyond the scope of this test method.
There is no similar or equivalent ISO standard.
This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
