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, health, and environmental 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.
ASTM D2613-01(2023) is the Standard Test Method for Calcium or Zinc in Paint Driers by the EDTA Method, developed by ASTM International. This standard specifies a titrimetric (wet chemical) procedure for determining calcium or zinc contents in liquid driers intended for use in the coatings industry. The method utilizes ethylenediaminetetraacetic acid (EDTA) as a titrant, and applies to pure liquid calcium or zinc driers that are soluble in a toluene-alcohol mixture. The test is not applicable to blends of driers or samples containing cations that also react with EDTA in alkaline media. The standard is integral for confirming the accuracy of the labeled metallic content in such driers and ensuring compliance with industry specifications.
