(Test Method)Standard Test Method for Calcium or Zinc in Paint Driers by EDTA Method
Standard Test Method for Calcium or Zinc in Paint Driers by EDTA Method
SIGNIFICANCE AND USE
4.1 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.
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.
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

7.1 Take a small sample of liquid drier from bulk using the procedures in Practice E300 appropriate for the size of the container:
Section 19 for tanks and tank cars or Section 23 for drums and cans.
NOTE 1—Liquid driers are normally homogeneous so that only simple physical tests, such as specific gravity or solids content, on top and bottom
samples from tanks, are required to confirm that separation has not occurred. Agitate drums in accordance with
