ISO 14554-2-2000 焊接质量要求 金属材料的电阻焊接 第2部分：基本质量要求.pdf

ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). 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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3.
Draft International Standards adopted by the technical committees are circulated to the member bodies for voting.
Publication as an International Standard requires approval by at least 75 % of member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this part of ISO 14554 may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.
International Standard ISO 14554-2 was prepared by the European Committee for Standardization (CEN) in collaboration with ISO Technical Committee TC 44, Welding and allied processes, Subcommittee SC 10, Unification of requirements in the field of metal welding, in accordance with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement).
Throughout the text of this standard, read "...this European Standard..." to mean "...this International Standard...".
ISO 14554 consists of the following parts, under the general title Quality requirements for welding — Resistance welding of metallic materials:
— Part 1: Comprehensive quality requirements
— Part 2: Elementary quality requirements
Annex A of this part of ISO 14554 is for information only.
Annex ZA provides a list of corresponding International and European Standards for which equivalents are not given in the text.
