Description of ASTM-D3969 2012ASTM D3969 - 01(2012)Standard Test Method for Zirconium in Paint Driers by EDTA MethodActive Standard ASTM D3969 | Developed by Subcommittee: D01.21 Book of Standards Volume: 06.01 ASTM D3969Significance and Use 4.1 The amount of zirconium drier used in oxidizing-type coatings significantly affects their drying properties. This test method may be used to confirm the stated content of a pure liquid zirconium drier manufactured for use by the coatings industry. 1. Scope 1.1 This test method covers the titrimetric determination of zirconium in zirconium driers used in the coatings industry and utilizes the disodium salt of ethylenediaminetetraacetic acid dihydrate (EDTA). 1.2 This test method is limited to the determination of the zirconium content of a liquid zirconium drier that does not contain other drier elements. The test method is not applicable to drier blends and does not differentiate hafnium from zirconium. 1.3 All cations that can be titrated with EDTA in acid media interfere and must not be present in the sample. 1.4 This test method has been tested for concentrations of 6 and 12?% zirconium, but there is no reason to believe that it is not suitable for higher or lower zirconium concentrations, provided specimen size is adjusted proportionately. 1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.6 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.
