1、Designation: D6827 02 (Reapproved 2016)Standard Test Method forZinc Analysis of Floor Polishes and Floor Polish PolymersBy Flame Atomic Absorption (A.A.)1This standard is issued under the fixed designation D6827; the number immediately following the designation indicates the year oforiginal adoption
2、 or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This laboratory test method covers the analysis of floorpolishes and floor p
3、olish polymers for total zinc content.1.2 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory li
4、mitations prior to use.2. Significance and Use2.1 This test method is generally accepted for the prepara-tion of floor polish and floor polish polymers for the analysis oftotal zinc content. Knowing the total zinc content of a floorfinish or polymer can aid in determining the proper disposalmethod o

6、ocedure5.1 Sample Preparation:5.1.1 Before a sample can be run for total zinc, it must beprepared so that any insoluble zinc will be solubilized and notremoved by the filtering process. By preparing the sample inthe following way, the analysis will be much more accurate(testing total zinc instead of
7、 soluble zinc). The prep methodwill also lessen the chance of clogging the nebulizer of theatomic absorption unit with particulate matter.5.2 Prep Method:5.2.1 ImportantAll glassware used must be washed with1:1 nitric acid solution and rinsed with deionized water toeliminate contamination.5.2.2 Weig
