ASTM D1524 Standard Test Method for Visual Examination of Used Electrical Insulating Oils of Petroleum Origin in the Field
ASTM D1524用過(guò)石油制電絕緣油現(xiàn)場(chǎng)目測(cè)檢查標(biāo)準(zhǔn)試驗(yàn)方法
By use of this test method the color and condition of a test specimen of oil may be estimated during a field inspection, thus assisting in the decision as to whether or not the sample should be sent to a central laboratory for full evaluation. Cloudiness, particles of insulation, products of metal corrosion, or other undesirable suspended materials, as well as any unusual change in color may be detected. For precise determination of color in the laboratory, Test Method should be used.
1. Scope
1.1 This test method for visual examination is applicable to mineral oils of petroleum origin that have been used in transformers, oil circuit breakers, or other electrical apparatus as insulating or cooling media, or both.
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered 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.
