BS EN 1297 is a European standard that discusses bitumen, plastic and rubber sheets for roof waterproofing. The main objective of BS EN 1297 is to ensure bitumen sheets that play a positive role in maintaining the structural integrity and protection of structures
BS EN 1297 specifies the method for exposure of factory made bitumen or plastic or rubber sheets for roof waterproofing to combined effects of long term exposure by UV radiation, elevated temperature and water as means of artificial ageing.
BS EN 1297 on artificial ageing of flexible sheets for roof waterproofing is useful for:
An artificial ageing test is used to determine the long-term effects of different stress levels in a shorter amount of time. As test specimens, flexible bitumen, plastic, or rubber sheets are cut from the product sample and exposed to an instrument with fluorescent UV lamps at prescribed irradiance, black standard temperature (BST), relative humidity, and cyclic water spraying. Artificial ageing tests are used to measure resistance to this exposure.
In this regard, BS EN 1297 provides the requirements for apparatus, sampling and preparation of test specimens and test procedure to be applied as a method for artificial ageing to all types of flexible sheets for roof waterproofing.
Thus, if you are a manufacturer of flexible sheets for roof waterproofing, complying with BS EN 1297 can help demonstrate the performance and durability of your product, ensuring that they are fit for purpose, and can withstand extreme environmental stresses.
