Door Industry Journal - Winter 2019

117 THE door industry journal winter 2019 2 Also online at: www.dijonline.co.uk Locks & Building Hardware The ANSI standards which refer to door closers are: • ANSI/BHMA A156.4-2013: Door Controls - Closers • ANSI/BHMA A156.8-2015: Door controls - Overhead Stops and Holders • ANSI/BHMA A156.15-2015: Closer Holder, Electromagnetic and Electromechanical • BHMA A156.17-2004 (R2010): Self Closing Hinges and Pivots Relcross sell a comprehensive range of heavy-duty ANSI grade hardware that is specified in high traffic, high impact settings including prisons, hospitals, schools, shopping malls and other public buildings across the UK. ANSI standard products have to be retested to EN standards in order to receive a CE Mark and be placed on the market in the UK. In general this does not pose a problem since quality ANSI approved products generally only ever need a small tweak at best to pass the EN tests. One of the key differences between an ANSI and EN certified door closer is in the material used in its construction. LCN ANSI-grade closers feature cast iron cylinders and forged steel working components. Cast iron is not only strong, hard and reliable, it is compatible with high-grade steel components and is highly resistant to wear from millions of opening and closing cycles. ANSI standards are reviewed periodically by ANSI and BHMA and in general change happens at a faster pace than with EN standards. Even so, the market innovation often outstrips these reviews as technology, manufacturing expertise and materials improvements are phased in by manufacturers As the UK’s principal distributor of ANSI standard hardware in the UK, Relcross offers a free technical specification and advisory service to assist you in the correct choice of equipment. Substantial stocks of most products are held and the Relcross team of trained specifiers will discuss problems, offer guidance, make recommendations and, most importantly, help on site if difficulties should occur.
