ISO 14554-2:20 13规定了在以下一项或多项中证明制造商或分包商生产满足指定质量要求的焊接结构的能力的要求:a)相关方之间的合同;b)应用标准;c)监管要求。
ISO 14554-2:20 13中包含的要求可以全部采用,如果不适用于相关结构,制造商可以选择性地删除这些要求。它们通过提供以下具体要求,为焊接控制提供了灵活的框架:1)情况1?合同中的电阻焊要求制造商或分包商拥有ISO 9001[1]以外的质量体系,并且记录在案的焊接控制对最终结构的整体完整性不太重要;2)案例2?电阻焊作为制造商或分包商开发质量体系的指南;3)案例3?应用标准中使用电阻焊作为其要求的一部分或相关方之间的合同中的参考文献。
ISO 14554-2:20 13:i)独立于待制造的焊接结构的类型;ii)定义生产工厂和现场焊接的质量要求;iii)为描述制造商生产焊接结构以满足指定要求的能力提供指南;iv)也可以用作评估制造商焊接能力的基础。
有关选择和使用的一般指南,请参见ISO 3834?1,同时意识到仅对电阻焊规定了全面和基本的要求。附录给出了ISO 14554-2:20 13和ISO 14554中电阻焊具体质量要求的总结比较?1.
ISO 14554-2:2013 specifies requirements for the demonstration of the capability of a manufacturer or a sub-contractor to produce welded constructions, fulfilling specified quality requirements, in one or more of the following: a) a contract between involved parties; b) an application standard; c) a regulatory requirement.
The requirements contained within ISO 14554-2:2013 can be adopted in full or can be selectively deleted by the manufacturer if not applicable to the construction concerned. They provide a flexible framework for the control of welding by providing specific requirments for: 1) Case 1?resistance welding in contracts which require the manufacturer or sub-contractor to have a quality system other than ISO 9001[1] and where the documented welding control has a minor importance to the overall integrity of the final construction; 2) Case 2?resistance welding as guidance to a manufacturer or sub-contractor developing a quality system; 3) Case 3?references in application standards which use resistance welding as part of their requirements or in a contract between relevant parties.
ISO 14554-2:2013: i) is independent of the type of welded construction to be manufactured; ii) defines quality requirements for welding both in production plants and on site; iii) provides guidance for describing the capability of a manufacturer to produce welded constructions to meet specified requirements; iv) can also be used as a basis for assessing the manufacturer in respect to his welding capability.
For general guidelines for selection and use, see ISO 3834?1, while being aware that only comprehensive and elementary requirements are specified for resistance welding. An annex gives a summary comparison of specific quality requirements for resistance welding in ISO 14554-2:2013 and ISO 14554?1.
