1、Designation: D 1669 07Standard Practice forPreparation of Test Panels for Accelerated and OutdoorWeathering of Bituminous Coatings1This standard is issued under the fixed designation D 1669; the number immediately following the designation indicates the year oforiginal adoption or, in the case of re
2、vision, the year of last 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 practice covers a procedure for the preparation ofaccelerated and outdoor weathering test pa
3、nels 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 SI units are to be regarded asstandard.1.3 This standard does not purport to address all of thesafety concerns, if any, associat
4、ed 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. (WarningMercury has been designated by EPA and many state agenciesas a hazardous material that can caus
5、e central nervous system,kidney, and liver damage. Mercury, or its vapor, may behazardous to health and corrosive to materials.

7、 Method for Penetration of Bituminous MaterialsE1 Specification for ASTM Liquid-in-Glass Thermometers3. Summary of Practice3.1 Heated bituminous material is poured onto a clean,heated, and masked aluminum panel. Care is taken to removeair bubbles. The bitumen is leveled in a press before solidify-in
8、g, and the coated panel is then cooled, cleaned, and measuredfor uniform thickness.4. Significance and Use4.1 This practice for preparation of test panels greatlyincreases the likelihood of achieving reproducible results insubsequent testing.5. Apparatus5.1 PanelA supporting metal panel on which the
9、 bitumi-nous coating is applied. It shall meet the following require-ments:5.1.1 Metal, Aluminum or Aluminum Alloy, as described inTable 2 of Specification B 209 under Alloy 3003-H14.35.1.2 FinishMill finish and process cleaned.5.1.3 Dimensions:5.1.3.1 Thickness0.64 to 1.90 mm (0.025 to 0.075 in.).5

Flatness shall be measured on
11、a true flat surface1This practice is under the jurisdiction ofASTM Committee D08 on Roofing andWaterproofing and is the direct responsibility of Subcommittee D08.02 on PreparedRoofings, Shingles and Siding Materials.Current edition approved Sept. 15, 2007.

Preparation of Metal Panels6.1 HandlingHandle the panel by the edges only and donot allow fingers to contact the face to be coated. Do
29、 notunwrap the panels until the day on which they are to be coated.This is to prevent oxidation and contamination of the face. Donot reuse the test panels.6.2 Precalibration and ClassificationMeasure the thick-ness of all panels at six representative points and classify theminto groups of identical
30、thickness.6.3 MarkingMark or drill the panels before or aftercoating, preferably afterwards. If marked or drilled beforecoating, take care to see that these operations do not alter theflatness of the panel by distortion or by leaving burrs.(WarningStamping identification numbers by means ofsteel die
31、s should be done with extreme caution to avoiddistortion of the panel or shattering of the coating.) Thepreferred method of marking is by scratching the previouslycoated panel with a hardened steel stylus. It is permitted tomark either the back of the panel or on the face at one end. The4The sole so
