Significance and Use
4.1 Knowledge of the phosphorus content, and thus the phosphorus-containing additives, in a lubricating oil or additive can be used to predict performance characteristics.

1. 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. 1.3 This test method is free from most interferences because the high insolubility of the quinoline phosphomolybdate precipitate leads to constant composition and freedom from most adsorbed or occluded impurities, especially from cations which would otherwise interfere in the subsequent titration of the precipitate. 1.4 Barium, calcium, magnesium, zinc, iron, aluminum, alkali salts, citric acid and citrates, chromium up to 18 times the phosphorus content, and titanium up to 3.5 times do not interfere with the test method. 1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.6 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.
