Quick Overview
Coru172 Black Flame Retardant Rubber is a Black 70° Shore EDPM flame retardant rubber sheeting. Warrington Fire UK has independently tested this product to European Railway standard for fire safety EN45545 HL3. It has very good resistance to ozone, along with a good resistance to dilute acids and bases. It also has low smoke release and low toxicity. Unlike most other flame-retardant rubber, the material is also halogen-free.
EN45545 is the European Standard for fire safety, protecting staff and passengers against onboard fires in rail vehicles. The HL3 rating is the highest hazard level that is certified for railway safety. It applies to manufacturers of all rail transport, including high-speed and regional trains as well as Metros and trams.
Received a Class 2 rating on BS 476 part 7: Surface Spread Flame Test. For a material to receive a Class 2 rating, the spread of flame must be no greater than 215mm in the first one and a half minutes of the test, with an overall spread of no more than 455m.
