UL 1897:Standard for Uplift Tests for Roof Covering Systems


Abstract 摘要
This test method provides a comparative measure of the uplift resistance for roofing systems by means of static differential pressure. The method does not necessarily simulate the actual dynamic uplift pressures encountered by roofing systems. Uplift pressures on a roofing system are dependent upon many factors such as wind gusts, building shape, edge configuration, and the terrain surrounding th
