(Test Method)Standard Test Method for Powdering of Floor Polish Films
Standard Test Method for Powdering of Floor Polish Films
SIGNIFICANCE AND USE
4.1 This is a comparative test method. If this method does not indicate powdering, it is still possible that the product in actual use may powder. Reference polishes should be used for comparison.
SCOPE
1.1 This test method covers a bench procedure for the determination of the degree of powdering of floor polishes under ambient conditions as well as conditions of low relative humidity.
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.3 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.
1.4 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.
