The work of preparing International Standards is normally carried out through ISO technical committees. 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, governmental 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 member bodies for voting. Publication as International Standard requires approval by at least two-thirds of the Member Bodies casting a vote. International Standard ISO 834-1 was prepared by Technical Committee ISO/TC 92, Fire safety, Subcommittee SC 2, Fire resistance. This first edition of ISO 834-1 cancels and replaces ISO 834:1975, together with Amendment 1:1979 and Amendment 2:1980, of which it constitutes a technical revision. The revision has been made because of the need for more accuracy and reproducibility in the test method. Its provisions are supplemented by the commentary material contained in part 3. ISO 834 consists of the following parts under the general title Fire-resistance tests - Elements of building construction: Part l: General requirements Part 3: Commentary on test method and test data application Part 4: Specific requirements for loadbearing vertical separating elements Part 5: Specific requirements for loadbearing horizontal separating elements Part 6: Specific requirements for loadbearing beams Part 7: Specific requirements for loadbearing columns Part 8: Specific requirements for non-loadbearing vertical separating elements Part 9: Specific requirements for non-loadbearing horizontal separating elements Part 1O: Method to determine the contribution of applied protection materials to structural metallic elements Part ll: Method to assess the contribution of applied protection materials to structural metallic elements ili
