1、Designation: D1669/D1669M 07 (Reapproved 2013)1Standard Practice forPreparation of Test Panels for Accelerated and OutdoorWeathering of Bituminous Coatings1This standard is issued under the fixed designation D1669/D1669M; the number immediately following the designation indicates theyear of original

2、 adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of lastreapproval. A superscript epsilon () indicates an editorial change since the last revision or reapproval.1NOTEUnits information was editorially corrected in July 2013.1. Scope1.1 This

3、practice covers a procedure for the preparation ofaccelerated and outdoor weathering test panels of bituminouscoatings. It is considered suitable for the preparation of filmthicknesses in the range from 0.25 to 2.54 mm 0.010 to 0.100in.1.2 The values stated in either SI units or inch-pound unitsare

4、to be regarded separately as standard. The values stated ineach system may not be exact equivalents; therefore, eachsystem shall be used independently of the other. Combiningvalues from the two systems may result in non-conformancewith the standard.1.3 This standard does not purport to address all o

5、f 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.
