Such fluids should only be filled into systems designed for their use and where recommended by the equipment manufacturer. Regular maintenance of these fluids is important. Detailed information on their maintenance, handling and associated safety procedures is given in IEC 60978 or can be obtained from the suppliers of these fluids.
4 Composition These products are organic phosphate esters with the organic constituents consisting entirely of aryl or substituted aryl groups. The composition of commercial fluids is complex and several different chemical types are available. Additives may be incorporated to improve stability and to reduce foaming. Use of viscosity index improvers is not permitted. Fluids may be dyed for identification purposes, if required. 5 Sampling Sampling shall be carried out on delivery in accordance with the relevant procedures described in 6.2 and 6.3 of ISO 3170. Additional information on sampling is given in IEC 60978. 6 Required characteristics The appearance of the fluid shall be clear and free from visible foreign matter when a representative sample of the fluid is examined at ambient temperature by transmitted visible light using a clear glass container of approximately 100 mm diameter. Fluids complying with this standard shall meet the limiting values in Table 1 when tested in accordance with the specified methods. 7 Precision and interpretation of test results Most of the methods of test specified in Table 1 contain a statement of the precision, i.e. repeatability and reproducibility to be expected from them. In case of dispute, the procedure described in ISO 4259 which uses precision data in the interpretation of test results, shall be used.
