ISO 20763:2004规定了通过叶片式液压泵的性能测定液压流体钢对钢抗磨性能的程序。ISO 20763:2004涵盖了一系列液压油，包括无水和水性，适用于高速滑动接触的应用，如叶片泵中的接触。 对于HM和HV类矿物油以及HFD类耐火流体，该方法适用于ISO 3448中规定的粘度等级ISO VG 32、ISO VG 46和ISO VG 68。在不同的规定条件下，该方法适用于ISO 12922中规定的HFA、HFB和HFC类相同粘度等级的含水耐火液压油。

ISO 20763:2004 specifies procedures for the determination of steel-on-steel anti-wear properties of hydraulic fluids by means of performance in a vane-type hydraulic pump. ISO 20763:2004 covers a range of hydraulic fluids, both anhydrous and aqueous, intended for applications where high-speed sliding contacts, such as those found in a vane pump, are encountered. For mineral oils of categories HM and HV, and fire-resistant fluids of category HFD, the method is applicable to viscosity classes ISO VG 32, ISO VG 46 and ISO VG 68, as specified in ISO 3448. Under different specified conditions, the method is applicable to aqueous fire-resistant hydraulic fluids in categories HFA, HFB and HFC, as specified in ISO 12922, within the same viscosity classes.
