标准范围

ISO 4263-1:2003规定了一种测定防锈和抗氧化矿物油老化性能的方法，该矿物油的密度小于水，用作汽轮机油（ISO 6743-5的TSA、TGA、TSE、TGE类、液压油（ISO 6743-4的HL、HM、HR、HV、HG类）和循环油（ISO 6743-6的CKB类）。含有合成成分的油可以通过该程序进行测试，但目前还没有此类液体的精度说明。本试验方法在规范中广泛使用，在比较易受水污染的油的氧化稳定性时被认为是有价值的。然而，由于大量的现场服务应用，该测试结果与实际服务性能之间的相关性可能会有显著差异，最好根据经验进行判断。

ISO 4263-1:2003 specifies a method for the determination of the ageing behaviour of rust- and oxidation- inhibited mineral oils having a density less than that of water, used as turbine oils (categories TSA, TGA, TSE, TGE of ISO 6743-5, hydraulic oils (categories HL, HM, HR, HV, HG of ISO 6743-4), and circulating oils (category CKB of ISO 6743-6). Oils containing synthetic components can be tested by this procedure, but no precision statement is available yet for such fluids.This test method is widely used in specifications and is considered of value in comparing the oxidation stability of oils that are prone to contamination with water. However, because of the large number of individual field service applications, the correlation between the results of this test and actual service performance can vary markedly, and is best judged on experience.
