IS 2297 : 2025 Gear Lubricants, Compounded - Specification
| ICS 75.100; 21.200 | PCD 25 |
1 SCOPE
1.1 This standard prescribes the requirements, methods of sampling and test for the gear lubricants intended for use in worm gear drives.
1.2 The lubricant shall conform to one of the eleven viscosity grades as distinguished by the prescribed viscosity limits given in Table 1.
1.3 These lubricants are primarily intended for use in enclosed and semi-enclosed worm gears operating under such conditions of load, temperature and sliding speed for which straight mineral oils are not adequate and EP (extreme pressure) type oils are not called for. These are, however, NOT SUITABLE for lubrication of hypoid gears. The lubricants covered by this standard are equivalent to the service designation API-GL-2.
