This International Standard specifies procedures for the evaluation of pressure drop flow characteristics of hydraulic filters and may serve as the basis for agreement between filter manufacturers and users. This standard also stipulates the measurement method of the pressure drop produced by the filter-related components (including the housing, the filter element and the bypass valve installed in the housing) under different flow rates and viscosities. This standard is applicable to all kinds of hydraulic filters using hydraulic pressure as the working medium. Hydraulic filters using other liquids as the working medium can refer to this standard.
