EN ISO 3834-2 requirements2.1 IntroductionEN ISO 3834-2 defines comprehensive quality requirements for fusion welding in workshopsand/or on site. Therefore compliance to the requirements of this part should provide the bestquality level achievable for the welding fabrication activities.2.2 Requirements review and technical reviewThe Manufacturer shall review the contractual and any other requirements together with anytechnical data relevant to the welding fabrication activities, in order to verify that the work content iswithin its capability to perform, that sufficient resources are available to achieve delivery schedulesand that documentation is clear and unambiguous. All information necessary to carry out themanufacturing operations shall be therefore available prior to the commencement of the work,otherwise it should be asked the purchaser2 to provide all the necessary data.Moreover the Manufacturer shall identify any variation between the final contract and previousquotations and notify the purchaser of any programme, cost or engineering changes that mayresult.EN ISO 3834-2 requirements2.1 IntroductionEN ISO 3834-2 defines comprehensive quality requirements for fusion welding in workshopsand/or on site.
