ASTM D2613-01(2006)

Standard Test Method for Calcium or Zinc in Paint Driers by EDTA Method

SIGNIFICANCE AND USE
This test method may be used to confirm the stated calcium or zinc content of pure liquid calcium or zinc driers soluble in toluene-alcohol and manufactured for use by the coatings industry.
SCOPE
1.1 This test method covers a titrimetric determination of calcium in liquid calcium driers and zinc in liquid zinc driers that can be dissolved in a toluene-alcohol mixture and utilizes the disodium salt of ethylenediaminetetraacetic acid dihydrate (EDTA).
1.2 This test method is not applicable to drier blends.
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 standard. No other units of measurement are included in this standard.
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.
