1 Scope
This method indicates the tendency of a lubricating oil to deteriorate on oxidation
under specified conditions. A measure of the deterioration is obtained by comparison
of the viscosity and carbon residue before and after oxidation.
The test is not suitable for additive-type oils (other than those containing ashless
additives) or those which form solid products or lose more than 10% by evaporation
during the test.
WARNING This part of BS 2000 calls for the use of substances and/or procedures that can be injurious to health if adequate precautions are not taken. It refers only to technical suitability and does not absolve the user from legal obligations relating to health and safety at any stage.
