3、th ISO12224-1:1997. Together with BSEN12224-2 it supersedes BS441:1980, which will be withdrawn upon publication of BSEN12224-2. Methods of analysis for tin alloys are contained in BS3338. The UK participation in its preparation was entrusted by Technical Committee NFE/27, Tin and tin alloys, to Sub

4、committee NFE/27/4, Solders and soldering fluxes, which has the responsibility to: aid enquirers to understand the text; present to the responsible international/European committee any enquiries on the interpretation, or proposals for change, and keep theUKinterests informed; monitor related interna

5、tional and European developments and promulgate them in the UK. A list of organizations represented on this subcommittee can be obtained on request to its secretary. Cross-references Attention is drawn to the fact that CEN and CENELEC standards normally include an annex which lists normative referen

Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmenta

24、l and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Draft International Standards adopted by the technical committees are circulated to the membe
