Standard Test Method for Lead in Paint Driers by EDTA Method (Withdrawn 2016)

Scope

1.1 This test method covers a titrimetric determination of lead in liquid paint driers that can be dissolved in glacial acetic acid and utilizes the disodium salt of ethylenediaminetetraacetic acid dihydrate (EDTA).

1.2 This test method is not applicable to drier blends. If driers other than cobalt are present, they may interfere by reacting with EDTA under the conditions used for analysis.

1.3 All cations that can be titrated with EDTA in alkaline media interfere and must not be present in the sample.

1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

1.5 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.

Significance and Use

The amount of lead drier used in oxidizing-type coatings significantly affects their drying properties. This test method may be used to confirm the stated lead content of pure liquid lead drier soluble in glacial acetic acid and manufactured for use by the coatings industry.
