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

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
