标准范围

ISO 4263-2:2003规定了ISO 6743-4和ISO 12922中规定的HFC类液压油老化性能的测定方法。在高温下，氧气、水和金属催化剂的存在会加速老化，流体降解后pH值和不溶物含量会发生变化。ISO 4263的其他部分规定了测定矿物油老化性能的类似程序，以及液压和其他应用中使用的特定类别的耐火流体。

ISO 4263-2:2003 specifies a method for the determination of the ageing behaviour of hydraulic fluids of category HFC as defined in ISO 6743-4 and specified in ISO 12922. The ageing is accelerated by the presence of oxygen, water and metal catalysts at elevated temperature, and the degradation of the fluid is followed by changes in pH value and insolubles content. Other parts of ISO 4263 specify similar procedures for the determination of the ageing behaviour of mineral oils and specified categories of fire-resistant fluids used in hydraulic and other applications.
