1.1 This test method covers the titrimetric determination of rare earth metals in liquid rare earth metal driers and utilizes the disodium salt of ethylenediaminetetraacetic acid dihydrate (EDTA).

1.2 This test method is limited to the determination of the rare earth metal content of a liquid rare earth metal drier that does not contain other drier elements. The method is not applicable to drier blends.

1.3 This test method has been tested in concentrations of 6% cerium and 6% rare earth metals, but there is no reason to believe that it is not suitable for higher or lower drier metal concentrations provided specimen size is adjusted accordingly.

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.
