Anotácia

These test methods cover procedures for sampling and testing prefabricated, reinforced, polymer-modified bituminous sheet materials designed for single- or multiple-ply application in roofing and waterproofing membranes. From each shipment or fraction thereof, select at random a number of rolls equal to one half the cube root of the total number of rolls in the lot. If the calculated number is fractional, express it as the next highest whole number. The load strain (tensile elongation and strain energy) properties shall be tested to meet the requirements prescribed. The tensile tear strength, moisture content, and water absorption of polymer-modified bituminous sheets shall be tested to meet the requirements prescribed. The dimensional stability, low-temperature flexibility, heat conditioning, and accelerated weathering of the polymer-modified bituminous sheets shall be tested to meet the requirements prescribed. The granule embedment, compound stability, coating thickness, low temperature unrolling, and precision and bias of the polymer-modified bituminous sheet materials shall be tested to meet the requirements prescribed.
