ASTM WK38365

    New Test Methods for Ultraviolet Conditioning of Photovoltaic Modules or Mini-Modules Using a Fluorescent Ultraviolet (UV) Lamp Apparatus

    (What is a Work Item?)

    Developed by Subcommittee: E44.09 | Committee E44 | Contact Staff Manager


    1. Scope

    1.1 This practice covers specific procedures and test conditions for performing ultraviolet exposures on photovoltaic modules, mini-modules, or materials using fluorescent ultraviolet lamps in accordance with Practices G151 and G154. This practice covers test conditions that meet the requirements for UV pre-conditioning in initial qualification tests of photovoltaic modules or mini-modules as published in international standards. 1.2 Units - The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.3 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.

    The PV industry performs qualification tests according to IEC standards. One of the tests is a UV pre-conditioning test, which is listed in at least three standards. The requirements of each are inconsistent, and there is significant confusion in the industry regarding how to perform the test. In addition, industry uses these tests as a basis for weathering/durability testing. This standard will give guidance on performing the tests so that different laboratories obtain comparable results. In addition, it will provide guidance on performing ultraviolet and moisture durability (weathering) tests using the same techniques.
