本标准规定了电气绝缘油中多氯联苯(PCBs)含量的气相色谱测定方法。本标准适用于被单一Aroclor或Aroclors混合物污染的电气绝缘油中PCBs的测定,还适用于askarels电气绝缘油混合物中PCB的测定,但不适用于来自其他污染源的PCBs的测定。一些含有卤化烃之类的电气绝缘油会干扰PCBs的测定,因此在没有进行预处理之前不能采用本标准进行测定。

4.1 The oxidation stability test of mineral transformer oils is a method for assessing the amount of sludge and acid products formed in a transformer oil when the oil is tested under prescribed conditions. Good oxidation stability is necessary in order to maximize the service life of the oil by minimizing the formation of sludge and acid. Oils that meet the requirements specified for this test in Specification D3487 tend to minimize electrical conduction, ensure acceptable heat transfer, and preserve system life. There is no proven correlation between performance in this test and performance in service, since the test does not model the whole insulation system (oil, paper, enamel, wire). However, the test can be used as a control test for evaluating oxidation inhibitors and to check the consistency of oxidation stability of production oils. 1.1 This test method determines the resistance of mineral transformer oils to oxidation under prescribed accelerated aging conditions. Oxidation stability is measured by the propensity of oils to form sludge and acid products during oxidation. This test method is applicable to new oils, both uninhibited and inhibited, but is not well defined for used or reclaimed oils. Note 1—A shorter duration oxidation test for evaluation of inhibited oils is available in Test Method D2112.Note 2—For those interested in the measurement of volatile acidity, reference is made to IEC Method 61125.8201;2 1.2 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.
