FIRE RESISTANCE TEST IN ACCORDANCE WITH BS 476: PART 22: 1987 Fire Doorset consisting of a Jeld-Wen UK leaf, Softwood frame and the Astra 4000 series concealed jamb mounted door closer.
With so much debate about fire safety lately, culminating in recent statements from the Ministry of Housing, Communities & Local Government (MHCLG) outlining new testing requirements for fire doors, there is an increasing emphasis on the suitability of door hardware for use on fire doors. The Astra 4003 concealed door closer, is fully certified, CE marked in accordance with the Construction Products Regulation, and tested to 500000 cycles, complying with BS EN1154 European harmonised standard.
Fire testing of doors consistently shows the top of the door and frame to be the most vulnerable area with regard to smoke and flame penetration - as seen in the above video. In our experience, a jamb mounted device, installed around the middle of the door, is much less onerous in this respect, and therefore clearly the safer option
