Physical Requirements7.1 UniformityA thoroughly stirred sample shall show noseparation of solvent or settling that cannot be overcome bymoderate stirring after standing for 72 h at ro
14、om temperature ina closed container. (See Test Methods D 6511, Section 5 onUniformity.)7.2 WorkabilityThe cement shall be of a consistency thatwill spread readily and permit troweling smooth coatings, 2 to6mm(116 to14 in.) thick, on prepared roofing, saturated felt,and metal surfaces at ambient temp
15、eratures above 10C (50F).7.3 Behavior at 60C (140F)The cement shall show noevidence of blistering, and sag or slide shall be no greater than6mm(14 in.). (See Test Methods D 6511, Section 12 onBehavior at 60C (140F).)7.4 Pliability at 0C (32F)There shall be no cracking orseparation of the cement from
16、 the metal. (See Test MethodsD 6511, Section 13 on Pliability at 0C (32F).)7.5 Adhesion to Damp, Wet, or Underwater SurfacesTheaverage of three test samples shall be greater than 80 %adhesion for compliance with Class II requirements. (See TestMethods D 6511, Section 17 on Adhesion to Damp, Wet, orU
17、nderwater Surfaces.)8. Sampling8.1 Sample the material from the original containers imme-diately after stirring to a uniform consistency in accordancewith Section 4, Sampling, of Test Methods D 6511. Restirsamples to ensure uniformity immediately before withdrawingportions for individual tests.9. Te
