Standard Test Method for Phosphorus in Lubricating Oils and Additives by Quinoline Phosphomolybdate Method
The following bibliographic material is provided to assist you with your purchasing decision:
Scope
1.1 This test method covers the determination of 0.005 to 10.0 mass % phosphorus in unused lubricating oil and additive concentrates. There is no reason to doubt its applicability to filtered, used lubricating oils, but no systematic study of this application has been made.
1.2 The test method is applicable to samples containing any of the phosphorus compounds in normal use.
Note 1—This test method extends the scope of the previous version of IP 149 and replaces IP 148 and the previous version of IP 149 as a referee method.
1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. For specific hazard statements, see 6.9.
Significance and Use
Knowledge of the phosphorus content, and thus the phosphorus-containing additives, in a lubricating oil or additive can be used to predict performance characteristics.
