Flexible Sheets for Waterproofing: Bitumen Sheets for Roof Waterproofing - Determination of Flexibility at Low Temperature
Also Known As:
BS EN 1109:2013 is a standard that specifies the method for determining the flexibility of bitumen sheets used for roof waterproofing at low temperatures. The test can be carried out on either the upper or lower face of the sheet, either at a predetermined temperature or at different temperature steps to determine the cold bending temperature, which is a limiting temperature. The purpose of this test is to confirm a minimum cold bending temperature for a product or to determine the specific cold bending temperature of a product after artificial aging.
In the case of sheets with the same bituminous compound on both sides and where the reinforcement is visually closer to the upper surface, the test is performed on the bottom face only. If the upper surface is covered with a non-woven or metal facing, the test is also performed on the bottom side only. However, if the upper surface is protected with a permanent light surface protection and the reinforcement is placed visually closer to the upper surface, the test is performed on the bottom side only.
