reflect progress in science, technology and systems. to maintain their currency, all standards are periodically reviewed, and new editions are published. between editions, amendments may be issued. standards may also be withdrawn. it is important that readers assure themselves they are using a current standard, which should include any amendments which may have been published since the standard was purchased.detailed information about joint australian/new zealand standards can be found by visiting the standards web shop at .au or standards new zealand web site at www.standards.co.nz and looking up the relevant standard in the on-line catalogue.alternatively, both organizations publish an annual printed catalogue with full details of all current standards. for more frequent listings or notification of revisions, amendments and withdrawals, standards australia and standards new zealand offer a number of update options. for information about these services, users should contact their respective national standards organization.we also welcome suggestions for improvement in our standards, and especially encourage readers to notify us immediately of any apparent inaccuracies or ambiguities. please address your comments to the chief executive of either standards australia or standards new zealand at the address shown on the back cover.the standard is downloaded from standard

was prepared by the joint standards australia/standards new zealand committee, welding consumables, to supersede as 1167.11993, welding and brazing filler metals, part 1: filler metal for brazing and braze welding.the objective of this standard is to specify requirements for brazing filler metal.the main changes in this edition have been driven by the increasing international concern at the risks of cadmium exposure and strategies at the global and australian levels, and were aimed at cadmium minimization. hence, the deletion of nine alloys containing cadmium (a4 to a7, a9 to a12 and a17) and the addition of six cadmium free alloys (a18 to a23) in table 1.other significant technical changes included the following:(a) deletion of alloys with very little usage (a1, a3, a13, a14 and b5).(b)reduction of cadmium impurity levels, in tables 1 and 2, from 0.05 to 0.01%.(c) updating of melting ranges to show true liquidus values, and addition of indicativebrazing temperature ranges in table 2.(d)deletion of alloy r4343 from table 4, and updating beryllium content from 0.0008%to 0.0003% to align with iso standards.in addition, appendix a has been fully revised to update references to current equivalenten, aws and iso standards.mechanical properties of brazed joints are not covered in this standard but will generally be found in the relevant application standards.the standard is downloaded from standard sharingthe term informative has been used in this standard to define the application of the appendix to which it applies. an informative appendix is only for information and

brazing and braze welding processes. it includes requirements for chemical composition and analysis, packing and marking. in addition, a standard form of colour coding designed to be mutually acceptable to manufacturers and users has been recommended for identification purposes.note: in this standard, the term brazing is used to imply both processes.2 referenced documentsthe following

american, and isoequivalents. standards a.au5 identificationindividual items of filler metal shall be identified by either embossing or colour coding. where colour coding is used, the colours employed should follow the colour guidance given in tables 1 to 4.6 form and sizespecification of the required form and size is a matter for the purchaser at the time of placing the order. if required, filler rods may be supplied coated with a suitable brazing flux.7 packingbrazing filler metals shall be packed to guard against damage and deterioration during transportation, handling and storage.8 general safety warningsa label shall be attached or a statement displayed with at least the following warning:protect yourself and others. read and understand this label.fumes and gases can be dangerous to your health.heat rays (infra red radiation from flame or hot metal) can injure eyes.warning:read and understand the materials safety data sheets on file with your employer and your employers safety practices.keep your head out of the fumes.use enough natural ventilation, or exhaust ventilation at the fume source, or both, to keep fumes and gases from the breathing zone and the general area.wear correct eye, ear and body protection.see as 1674.1, as 1674.2, wtia technical note 7 and wtia fume minimization guidelines, or our fillermetal suppliers recommendations for further information.do not
