适用范围

4.1 The useful life of photovoltaic modules may depend on their ability to withstand periodic exposure to high wind forces, cyclic loads induced by specific site conditions or shipment methods, high loads caused by accumulated snow and ice on the module surface, and twisting deflections caused by mounting to non-planar surfaces or structures. The effects on the module may be physical or electrical, or both. Most importantly, the effects may compromise the safety of the module, particularly in high voltage applications, or where the public may be exposed to broken glass or other debris.

4.2 These test methods describe procedures for mounting the test specimen, conducting the prescribed mechanical tests, and reporting the effects of the testing.

4.2.1 The mounting and fastening method shall comply with the manufacturer's recommendations as closely as possible. If slots or multiple mounting holes are provided on the module frame for optional mounting point capability, the worst-case mounting positions shall be selected in order to subject the module to the maximum stresses.

4.2.2 If an unframed module is being tested, the module shall be mounted in strict accordance with the manufacturer's instructions using the recommended attachment clips, brackets, fasteners or other hardware, and tightened to the specified torque.

4.2.3 The test specimen is mounted on a test base in a planar manner (unless specified otherwise), simulating a field mounting arrangement in order to ensure that modules are tested in a configuration that is representative of their use in the field.

4.2.4 During the twist test, the module is mounted in a manner simulating a non-planar field mounting where one of the fastening points is displaced to create an intentional twist of 1.2°.

4.3 Data obtained during testing may be used to evaluate and compare the effects of the simulated environments on the test specimens. These test methods require analysis of both visible effects and electrical performance effects.

4.3.1 Effects on modules may vary from no changes to significant changes. Some physical changes in the module may be visible even though there are no apparent electrical performance changes. Conversely, electrical performance changes may occur with no visible change in the module.

4.3.2 All conditions of measurement, effects of the test exposure, and any deviations from these test methods must be described in the report so that an assessment of their significance can be made.

4.4 If these test methods are being performed as part of a combined sequence with other mechanical or nonmechanical tests, the results of the final electrical test (7.2) and visual inspection (7.3) from one test may be used as the initial electrical test and visual inspection for the next test; duplication of these tests is unnecessary unless so specified.
