(Practice)Standard Practice for Preparation of Test Panels for Accelerated and Outdoor Weathering of Bituminous Coatings
Standard Practice for Preparation of Test Panels for Accelerated and Outdoor Weathering of Bituminous Coatings
SIGNIFICANCE AND USE
4.1 This practice for preparation of test panels greatly increases the likelihood of achieving reproducible results in subsequent testing.
SCOPE
1.1 This practice covers a procedure for the preparation of accelerated and outdoor weathering test panels of bituminous coatings. It is considered suitable for the preparation of film thicknesses in the range from 0.25 to 2.54 mm [0.010 to 0.100 in.].
1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the 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 and health practices and determine the applicability of regulatory limitations prior to use. (Warning—Mercury has been designated by EPA and many state agencies as a hazardous material that can cause central nervous system, kidney, and liver damage. Mercury, or its vapor, may be hazardous to health and corrosive to materials. Caution should be taken when handling mercury and mercury-containing products. See the applicable product Material Safety Data Sheet (MSDS) for details and EPA's website, http://www.epa.gov/mercury/faq.htm, for additional information. Users should be aware that selling mercury or mercury-containing products, or both, into your state may be prohibited by state law.)
