Flexible sheets for waterproofing - Bitumen sheets for roof waterproofing - Determination of flexibility at low temperature

active, Most Current
Organization: CEN
Publication Date: 1 April 2013
Status: active
Page Count: 14
ICS Code (Binders. Sealing materials): 91.100.50
scope:

This European Standard specifies the determination of flexibility of bitumen sheets at low temperatures. The test can be carried out on the upper or lower face of the sheet either at a predetermined temperature or successively at different temperature steps to determine the cold bending temperature which represents a limiting temperature. Therefore, the test can be used to confirm a minimum cold bending temperature for a product or to determine the specific cold bending temperature for the product e.g. to determine the change of these properties as a result of artificial ageing.

In the case of sheets with the same bituminous compound on both sides and where the reinforcement is placed in the cross section 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 (e.g. tissue, fleece etc.) or metal facing, the test is performed on the bottom side only.

If the sheet on the upper surface is covered with permanent light surface protection and where the reinforcement is placed in the cross section visually closer to the upper surface, the test is performed on the bottom side only.
