The use of type C lubricating oils is recommended in particular for circulation and splash lubricatio
9、n. Type C lubricating oils can also be used as hydraulic oils and general purpose lubricating oils or engine oils. Where the requirements for the resistance to ageing and/or corrosion protection are higher, type CL lubricating oils in accordance with DIN 51517-2 are to be used. In cases where the re
10、quirements for the anti-wear protection in the mixed friction zone are higher, type CLP lubricating oils in accordance with DIN 51517-3 are preferred. When using type C lubricating oils for machine tools, DIN 8659-2 also needs to be taken into account. 2 Normative references The following documents,

DIN 51517-1:2014-02 8 Annex A (normative) Read-across guidelines for the application to different ISO viscosity grades (ISO VG) The read-across guideline
33、s shall specify which properties listed in Table A.1 (minimum requirements) are to be determined explicitly for the different ISO viscosity grades (ISO VG) of this standard and where an extrapolation/interpolation (read-across) is permitted. Depending on the respective property, a read-across may be
34、 permitted or not. If a read-across is permitted, Table A.1 specifies which ISO viscosity grade is to be tested. In principle, this may be the lowest, the highest or the best-selling ISO viscosity grade of a lubricating oil series. Table A.1 shows the read-across procedure. Read-across according to
35、Table A.1 is only applicable within a homologous series of lubricants of different ISO viscosity grades (ISO VG). Lubricants of a homologous series within the meaning of this definition are made up of base stock combinations of the same base stock types. Variations of the base stock components shall
36、 only be admissible within the respective API group. The addition of additives to a homologous series within the meaning of this definition shall be identical for all ISO viscosity grades. As a departure from this, only quantitative adjustments of the foam and pour point depressant additives used sh
37、all be admissible. Identical components within the meaning of this definition are base stocks and additives that have been manufactured or bought by the lubricating oil manufacturer in accordance with identical specifications and registered under identical CAS or REACH numbers. In the case of identi
38、cal components originating from different sources or batches, it is the lubricating oil manufacturers responsibility to ensure equal performance by suitable quality assurance measures and to document it.
