THE British Association of Reinforcement (BAR) has warned construction clients and contractors to check that their prefabricated reinforcement has been welded by a fabricator who is fully certified to the new CARES Technical Appendices 11 and 12. The warning follows industry tip-offs that some fabricators are promoting their welded reinforcement as CARES approved when, in fact, they are not fully approved.The new CARES technical appendices cover welding to the International Standard ISO 17660 and the new British Standard BS 8548: 2017 Guidance for arc welding of reinforcing steel. The previous appendices and the associated BS 7123:1989 Specification for metal arc welding for concrete reinforcement have been withdrawn.
