3 Sampling
Sampling of hydraulic fluids for the purposes of this International Standard shall be carried out in accordance with the appropriate procedure described in ISO 3170. A representative sample shall be evaluated.
Any drum, barrel, tanker, compartment or any type of container delivered to the end user may be sampled and analysed at the request of the purchaser.
4 Requirements 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 health 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 exists 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 used in cases of dispute.ISO 12922-2012 pdf free download.
