ASTM D5147/D5147M-18 PDF Download

The ASTM D5147/D5147M-18 standard provides procedures for sampling and testing prefabricated, reinforced, polymer-modified bituminous sheet materials used for roofing and waterproofing membranes. The standard covers a range of products that may have different surfacing materials on one side. The testing methods outlined in the standard help ensure that the materials meet certain property requirements.

The standard specifies that a random selection of rolls from each shipment or fraction thereof should be tested. The load strain (tensile elongation and strain energy) properties, tensile tear strength, moisture content, water absorption, dimensional stability, low-temperature flexibility, heat conditioning, accelerated weathering, granule embedment, compound stability, coating thickness, low temperature unrolling, and precision and bias of the polymer-modified bituminous sheets are all tested to determine if they meet the prescribed requirements.

It is important to note that not all tests are required for every product. The specific tests that need to be conducted depend on the product and are indicated in the corresponding product standards, which include Specifications D6162/D6162M, D6163/D6163M, D6164/D6164M, D6222/D6222M, D6223/D6223M, D6298/D6298M, and D6509/D6509M.
