This Australian Standard was prepared by Committee MT/5, Lead and Lead Alloys. It was approved on behalf of the Council of Standards Australia on 8 March 1991 and published on 13 May 1991.
The following interests are represented on Committee MT/5: Australian Lead Development Association Confederation of Australian Industry Metal Trades Industry Association of Australia Telecom Australia Additional interests participating in preparation of Standard: Aeronautical Research Laboratory, Salisbury Australian Tin Information Centre Electronics industry organizations Solder manufacturing organizations
Review of Australian Standards. To keep abreast of progress in industry, Australian Standards are subject to periodic review and are kept up to date by the issue of amendments or new editi ons as necessary. It is important therefore that Standards users ensure that they are in possession of the latest editi on, and any amendments thereto. Full details of all Australi an Standards and related publications will be found in the Standards Australia Catalogue of Publications; this information is supplemented each month by the magazine The Australian Standard, which subscribing members receive, and which gives detail s of new publi cati ons, new edit ions and amendments, and of withdrawn Standards. Suggesti ons for improvements to Australi an Standards, addressed to the head off ice of Standards Australi a, are welcomed. Noti fi cati on of any inaccuracy or ambiguity found in an Australian Standard should be made without delay in order that the matter may be investigated and appropriate action taken.

This Standard was prepared by the Standards Australia Committee on Lead and Lead Alloys under the direction of the Metals Standards Board, to supersede AS 1834.11986, Solder alloys. The revised Standard is technically the same as the previous edition except that it incorporates the two amendments. As the result of the inclusion of these amendments, a lead-free tin-copper alloy has been added for general use in plumbing applications, particularly for capillary fittings and for joining copper tube, and a lead-free tin-copper-silver alloy has been added for the joining of copper, ferrous and nickel alloys. Both alloys are for use in potable water systems. This Standard is one of a proposed series of Standards covering materials for soldering. Currently, the only other Standard in the series is AS 1834.21986, Flux-cored solders.

STANDARDS AUSTRALIA Australian Standard Material for soldering Part 1: Solder alloys
1 SCOPE This Standard specifies the chemical composition requirements for tin-lead and other tin-containing solder alloys supplied in the cast, wrought, paste, or powder form. It is not applicable to working solder baths which may be subject to other impurity requirements.
NOTES: 1 For the purpose of this Standard, wrought includes ri bbon, wir e, rod and preforms. 2 Advice and recommendations on informati on to be suppli ed by the purchaser at the ti me of enquiry and order are contained in Appendix A. 3 Typical propert ies and uses of solders specif ied in this Standard are given in Appendix B. 4 The contaminant li mits for working solder baths used for the solderi ng of pri nted board assemblies are given in AS 3508.1.
2 REFERENCED DOCUMENTS The following documents are referred to in this standard: AS 1671 Lead and lead alloys 1671.1 Part 1: Determination of antimony contentFlame atomic absorption spectrometric method 1671.2 Part 2: Determination of low concentrations of antimony in lead alloys containing not more than 2.5 percent arsenic and 0.10 percent copperTitrimetric method 1671.3 Part 3: Determination of high concentrations of antimony in lead alloys containing not more than 2.5 percent arsenic and 1.0 percent copperTitrimetric method 1671.4 Part 4: Determination of tin in antimonial leadFlame atomic absorption spectrometric method 2292 Methods for the analysis of solders 2292.1 Part 1: Determination of tin (volumetric method) 2292.2 Part 2: Determination of silver, bismuth, cadmium, copper, antimony, iron and zincFlame atomic absorption spectrometric method 2534 Lead and lead alloysSampling and preparation of samples for chemical analysis 3508 Printed board assemblies 3508.1 Part 1: Preparation, handling and assembly BS 3338 Methods for the sampling and analysis of tin and tin alloys 3338.12 Part 12: Methods for the sampling of solders ASTM B32 Specification for solder metal E46 Method for chemical analysis of lead- and tin-base solder 3 DESIGNATION The solder designation shall consist of the following components (a) the number of this Australian Standard, i.e. AS l834.1; (b) the nominal tin content, followed by the chemical symbol for tin; and (c) the nominal contents of any other alloy additions, each followed by the chemical symbol for the element. Example 1 AS 1834.1/70Sn. Example 2 AS 1834.1/30Sn/1.8Sb. Example 3 AS 1834.1/95Sn/5Sb.
NOTE: The lead content is not included in the designation.
4 CHEMICAL COMPOSITION 4.1 General The chemical composition of solder alloys shall meet the requirements of Table 1. 4.2 Methods of sampling and analysis Methods used for sampling for chemical analysis shall not be less accurate than those given in AS 2534, BS 3338.12, and ASTM B32. The methods of chemical analysis shall not be less accurate than those specified in AS 1671.1, AS 1671.2, AS 1671.3 and AS 1671.4, AS 2292.1 and AS 2292.2, BS 3338 and ASTM E46.
