Scope: This standard specifies the test methods for evaluating the compatibility of standard elastomers with hydraulic fluids. The standard elastomers are manufactured according to the specified formula and process, and are used for basic comparison of fluids. This standard provides the formulations, mixing procedures and vulcanization procedures of five kinds of elastomeric compounds: a) nitrile rubber (NBR1 and NBR2); b) fluororubber (FKM2); c) EPDM rubber (EPDM1); d) Hydrogenated nitrile rubber (HNBR1). This procedure evaluates the effects of mineral-based hydraulic fluids, flame-retardant hydraulic fluids, and biodegradable hydraulic fluids on elastomers by measuring the physical properties of corresponding test elastomer standard specimens before and after immersion under controlled conditions. This standard does not provide the actual use of the elastomer material formulations, if necessary, the actual use of elastomers can be tested using these compatibility procedures.
