1、Designation: D 3207 92 (Reapproved 2002)Standard Test Method forDetergent Resistance of Floor Polish Films1This standard is issued under the fixed designation D 3207; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last

2、 revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 This test method covers a bench procedure for measur-ing the detergent resistance properties of floor polishes.1.2 This s

3、tandard 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 limitations prior to use.2.
