Standard Test Method for Zinc Analysis of Floor Polishes and Floor Polish Polymers By Flame Atomic Absorption (A.A.)

SIGNIFICANCE AND USE
2.1 This test method is generally accepted for the preparation of floor polish and floor polish polymers for the analysis of total zinc content. Knowing the total zinc content of a floor finish or polymer can aid in determining the proper disposal method of used or unwanted product.
SCOPE
1.1 This laboratory test method covers the analysis of floor polishes and floor polish polymers for total zinc content.  
1.2 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.  
1.3 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.
