18、all apply to this specification.3.2 Definitions of Terms Specific to This Standard:3.2.1 radiation control coating (RCC), na radiation control coating is a material that is designed to have a high solarreflectance (above 0.8) and a high infrared emittance (above 0.8) for long wavelength radiation.3.

19、2.2 solar reflectance, nsolar reflectance is the fraction of incident solar radiation that is reflected.4. Significance and Use4.1 It is recognized that the solar reflectance of RCCs will be reduced by soiling, which is caused by the accumulation of dirt,dust and other contaminants on the surface. T

20、he soiling, on the roof, will differ from location to location and from environmentto environment. It is possible that soiling rates are affected by the slope of the surface, the roughness of the surface, thecharacteristics of the dust in the air, the dust content of the air and the degree of growth

21、 of mildew and other organisms on thesurface. Low slopes, rough surfaces, dusty air and persistent moisture and conditions of high humidity are all conducive to soiling.At this time there are insufficient observations available to predict the amount of soiling for a given locale or the effect of the

22、 soilingon solar reflectance. Nor have any test procedures been developed to determine the ease with which the RCCs can be cleaned andthe degree to which the solar reflectance can be restored. It is suggested that users examine the potential for soiling at theapplication site and determine if the cl

23、eaning methods suggested by the manufacturer are likely to be adequate to maintain solarreflectance at an acceptable level, for the type of soiling expected5.
