This European Standard specifies general rules (test procedures, test pieces) for the specification and approval of brazing procedures for all materials, metallic and non-metallic. It is anticipated that, where necessary, specific requirements for individual industries will be developed within this framework and detailed in the relevant application standard. The recommended format for the procedure approval certificate is given in annex B. It assumes that the brazing procedure specifications are used in production and, in the case of manual flame brazing, by competent brazers approved in accordance with EN 13133, where relevant.
