    Abstract - (Show below) - (Hide below)

    This standard specifies a methodology for determination of the characteristic values necessary for the design of welded constructions for example vessels and tanks, ventilation ducting, containers and apparatus. It is assumed that due regard is paid to the standards and Codes of Practice listed in clause 2 as far as the choice of materials and their processing are concerned. The data is applicable for static loading. The relevant EN-Standards or ISO-Standards are applicable to the design calculations, dimensions, construction and testing of the various structures.
