(Practice)Standard Practice for Evaluation of Automotive Polish
Standard Practice for Evaluation of Automotive Polish
SIGNIFICANCE AND USE
4.1 This practice is intended to define the properties to be tested, the apparatus to use, and the comparisons of product performance. It is recognized that considerable discretion exists among formulators and marketers of automotive polish on what properties or performance characteristics are most important for their products. This practice is flexible enough to honor this fact within the confines of the automotive polish definition.
4.2 The methods of this practice are subjective and empirical in order to conform to the basic practices of the industry and to allow flexibility in testing.
SCOPE
1.1 This practice covers testing properties and apparatus used in evaluating the performance of automotive polishes. This practice is applicable to products that are commonly referred to as car/auto wax, cleaner wax, polish, etc.
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this 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.
