    WK30948

    1. Scope

    1.1 This test method describes the determination of byproducts of cellulosic materials degradation found in electrical insulation systems that are immersed in insulating liquid. Such materials include paper, pressboard, wood, and cotton materials. This test method allows the analysis of methanol and ethanol from the sample matrix by headspace (HS)-gas chromatography(GC)-mass spectrometry (MS) or GC-flame ionization detection (FID). 1.2 This test method has been used to test for methanol and ethanol in mineral insulating oils and high fire-point electrical insulating oils of mineral origin. The applicability of this test method to other insulating liquids has not yet been determined. 1.3 Units--The values stated in SI units are to be regarded as the standard. No other units of measurement are included in this standard. 1.4 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.
