Th
20、is International Standard does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this International Standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. 1
21、 Scope This International Standard specifies the minimum requirements of unused fire-resistant and less-flammable hydraulic fluids for hydrostatic and hydrodynamic systems in general industrial applications. It is not intended for use in aerospace or power-generation applications, where different re
22、quirements apply. It provides guidance for suppliers and end users of these less hazardous fluids and to the manufacturers of hydraulic equipment in which they are used. Of the categories covered by ISO 6743-4, which classifies the different types of fluids used in hydraulic applications, only the f
23、ollowing are detailed in this International Standard: HFAE, HFAS, HFB, HFC, HFDR and HFDU. Types HFAE, HFAS, HFB, HFC and HFDR are “fire-resistant” fluids as defined by ISO 5598. Most HFDU fluids, while displaying an improvement in combustion behaviour over mineral oil, fall outside this definition
24、and are more appropriately considered “less-flammable” fluids. NOTE For the purposes of this International Standard, the terms “% (m/m)” and “% (V/V)” are used to represent, respectively, the mass fraction and the volume faction of a material. 2 Normative references The following referenced document

43、for fire-resistant hydraulic fluids and less-flammable hydraulic fluids For the purposes of this International Standard, fluids shall be classified according to ISO 6743-4. Guidelines for their selection and use can be found in ISO 7745 and CEN/TR 14489. The latter also includes information on healt
44、h and safety requirements. Where applicable and when tested in accordance with the specified methods, fluids shall meet the limit values indicated in Table 1 (HFAE and HFAS fluids), Table 2 (HFB and HFC fluids) and Table 3 (HFDR and HFDU fluids). It should be noted that a significant variation exist
45、s in the level of fire resistance displayed by the different fluid types. The majority of test methods specified within Tables 1 to 3 contain a statement of precision (repeatability and reproducibility). ISO 4259, which covers the use of precision data in the interpretation of test results, shall be
