All NABIC safety valves were originally designed and tested in accordance with the requirements of BS 6759 and are now compliant with BS EN 1SO 4126-1:2013. Boilers and pressure vessels, designed to BS specifications, usually require the fitting of a safety valve which complies with BS EN 1SO 4126-1:2013. NABIC valves are also designed to meet Pressure Equipment Directive guidelines - PED 97/23/EC and Article 13 of 2014/68/EU.
