适用范围：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. This standard applies to a wide range of thermoplastics materials, for example: Polyethylene (PE), Polypropylene (PP), Polyvinyl Chloride (PVC) and Polyvinylidene Fluoride (PVDF). Annex A gives minimum properties for specific grades of these materials. The use of other thermoplastics is permitted, provided that their creep properties exceed the minimum values given in annex A for the known materials. Properties should be determined in accordance with the relevant ISO and EN standards. This allows the introduction of thermoplastics with improved properties as appropriate data becomes available.
