Standard Test Method for Furanic Compounds in Electrical Insulating Liquids by High- Performance Liquid Chromatography (HPLC)

1.1 This test method covers the extraction from test specimens and detection of products of the degradation of cellulosic materials such as paper, pressboard, and cotton materials typically found as insulating materials in electrical equipment. These degradation products are furanic compounds, commonly referred to as furan-like, furanoid, furans, or substituted furan compounds. This test method allows either liquid/liquid or solid phase extraction (SPE) of the furanic compounds from the sample matrix followed by analysis for specific furanic compounds by HPLC.

1.2 The individual furanic compounds that may be identified and quantified include the following:
