ASTM D5636/D5636M-94 (R2017) PDF Download

The ASTM D5636/D5636M-94 (R2017) standard aims to simulate the behavior of roofing and waterproofing felts or sheet materials during the unrolling process under actual field conditions. The purpose of this test method is to provide insight into the physical properties of these materials and measure their relative behavior during low temperature unrolling in a laboratory setting.

It is important to note that the data obtained from this test method does not allow for service life prediction or the assessment of the material's ability to be installed at the tested temperature. While the temperature at the time of unrolling is believed to impact the performance of roofing and waterproofing membranes, the direct correlation between the test data and actual performance is unknown and dependent on the specific materials and exposure.

In terms of scope, this standard covers the testing and analysis of surface cracking resulting from low temperature unrolling of roofing materials composed of bituminous impregnated felts and reinforced polymer modified bituminous sheet materials. These products may have various surfacing materials on one side.
