ASTM D117-02 石油电绝缘油取样试验方法和规范的标准指南

1.1 This guide describes methods of testing and specifications for electrical insulating oils of petroleum origin intended for use in electrical cables, transformers, oil circuit breakers, and other electrical apparatus where the oils are used as insulating, or heat transfer media, or both.1.2 The purpose of this guide is to outline the applicability of the available test methods. Where more than one is available for measuring a given property, their relative advantages are described, along with an indication of laboratory convenience, precision, (95 % confidence limits), and applicability to specific types of electrical insulating oils.1.3 This guide is classified into the following categories: Sampling Practices, Physical Tests, Electrical Tests, Chemical Tests, and Specifications. Within each test category, the test methods are listed alphabetically by property measured.

BS EN 50353:2001 绝缘油.用显微镜计数法测定纤维污染物

This European Standard specifies two methods for determining the fibre contamination of mineral insulating oil used in electrotechnical equipment, based on filtering a sample of oil and examining and counting the number of fibres on the surface of the filter using an optical microscope. Fibres down to 100 μm in length can be sized and counted by these methods. The methods are applicable both to unused oils and to oils in service. The method specified in the main text is applicable to oil samples taken from barrelled oil or from electrotechnical equipment in service, in which the fibre concentration is expected to be relatively high. The alternative method specified in annex A is applicable to samples taken from new oil in bulk containers, or from large transformers which have not been operated much since they were filled, in which the fibre concentration is expected to be relatively low. NOTE These methods are also suitable for other insulating liquids such as silicones and synthetic esters.
