1、Designation: D1669 07 (Reapproved 2013)Standard Practice forPreparation of Test Panels for Accelerated and OutdoorWeathering of Bituminous Coatings1This standard is issued under the fixed designation D1669; the number immediately following the designation indicates the year oforiginal adoption or, i
2、n the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This practice covers a procedure for the preparation ofaccelerated and outdoor wea
3、thering 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 SI units are to be regarded asstandard.1.3 This standard does not purport to address all of thesafety concerns, i
4、f 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. (WarningMercury has been designated by EPA and many state agenciesas a hazardous materia
5、l that can cause central nervous system,kidney, and liver damage. Mercury, or its vapor, may behazardous to health and corrosive to materials.

17、0, West Conshohocken, PA 19428-2959. United States15.1.6 StoragePanels shall be stored in a dry, well-ventilated place to prevent condensation and possible stainingor corrosion.5.2 PressThe press shall be capable of delivering a4500-kg (10 000-lb) thrust and be equipped for using platens152 by 152 m
18、m (6 by 6 in.) or larger platens.55.3 PlatensThe platens shall be 152 by 152 mm (6 by 6in.) or larger in size and suitable for use with the press. (Platenscan be purchased with the press.) It is preferable that bothplatens have thermostatically controlled units capable of heat-ing them to temperatur
19、es up to 260C (500F).5.4 Metal Spacers The metal spacers shall be 13 mm (12in.) wide and at least 152 mm (6 in.) long and of suitablethickness so that the proper thicknesses of bitumen films can beapplied.6To cover the range from 0.254 to 2.54 mm (0.010 to0.100 in.), the following supply of metal sp
20、acers is adequate:40.038 mm (0.0015 in.)40.051 mm (0.002 in.)40.076 mm (0.003 in.)40.127 mm (0.005 in.)40.229 mm (0.009 in.)40.254 mm (0.010 in.)40.305 mm (0.012 in.)40.330 mm (0.013 in.)40.081 mm (0.015 in.)5.5 Kraft Paper The kraft paper shall be from 64 to 191m (0.0025 to 0.0075 in.) in thickness
21、.5.6 Release Paper Silicone- or TFE-fluorocarbon-coatedrelease paper shall be cut to a size large enough to cover theplatens of the press. It must be easily removed at roomtemperature without damaging the bitumen film. (See Note 1.)NOTE 1Dextrin-coated paper is also allowed to be used as a releasepa

It must not leave a residue that cannot be removed by water.Asmalltank through which lukewarm water (below 27C (80F) is running shallbe used for removing dextrin-coated paper from finished panels.5.7 Heating Equipment:5.7.1 One gas or electrically heated oven capable of warm-ing the uncoated pa
23、nels, thermostatically controlled so atemperature range from 93 to 204C (200 to 400F) can bemaintained. A hot plate or any suitable plate-type heating unitcapable of thermostatically controlling the temperature be-tween 93 to 204C (200 and 400F) would be adequate.5.7.2 One gas or electrically heated
24、 hot plate or oven forheating the bitumen, controlled so that container temperatureswill not exceed 316C (600F).5.8 Melting ContainerA 17-kg (6-oz.) min. container ofsuitable size in which the bitumen can be melted, similar intype to that specified in Test Method D5.5.9 Thermometers:5.9.1 One ASTM P

Preparation of Metal Panels6.
30、1 HandlingHandle the panel by the edges only and donot allow fingers to contact the face to be coated. Do 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 Classification Me
31、asure the thick-ness of all panels at six representative points and classify theminto groups of identical 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 o
32、f the panel by distortion or by leaving burrs. (WarningStamping identification numbers by means of steeldies should be done with extreme caution to avoid distortion ofthe panel or shattering of the coating.) The preferred method ofmarking is by scratching the previously coated panel with ahardened s
33、teel stylus. It is permitted to mark either the back ofthe panel or on the face at one end. The masking tapesurrounding the coated portion of the panel will leave a clean,uncoated area suitable for marking when the tape is strippedoff.5The sole source of supply of the apparatus (Laboratory Model Car
