本文件规定了最大允许压力PS等于或小于以下值的压力容器和压力容器零件的设计、材料、制造和试验要求: -当含有第1组或第2组中的气体或液体时为100巴 -仅含第2组液体时为1000巴。 壳体壁厚不超过60 mm，由铁素体或奥氏体球墨铸铁制成。壳体的厚度限制不适用于法兰、加强件、凸台等的厚度。 注1:奥氏体球墨铸铁牌号主要用于高温和低温应用及其耐腐蚀性能。 注2:表5.1-1和表5.1-2列出了球墨铸铁的允许等级。使用条件见第4条。 本文件（EN 13445-6）不包括铁素体和奥氏体等级的片状石墨铸铁等级，断后伸长率等于或小于15%，明确排除在外。EN 15776中给出了使用断后伸长率等于或小于15%的铸铁的要求。

This document specifies requirements for the design, materials, manufacturing and testing of pressure vessels and pressure vessel parts intended for use with a maximum allowable pressure, PS, equal or less than: - 100 bar when containing gases or liquids in group 1 or 2 - 1000 bar when containing liquids in group 2 only. and shell wall thicknesses not exceeding 60 mm, which are constructed of ferritic or austenitic spheroidal graphite cast iron. The thickness limitation of the shell does not apply to thickness of flanges, reinforcements, bosses etc. NOTE 1 Austenitic spheroidal graphite cast iron grades are principally used for high and low temperature applications and for their corrosion resistance properties. NOTE 2 The allowable grades of spheroidal graphite cast iron are listed in Tables 5.1-1 and 5.1-2. Service conditions are given in Clause 4. This document, EN 13445-6, does not include lamellar graphite cast iron grades for ferritic and austenitic grades with, with an elongation after fracture equal or less than 15 % which are explicitly excluded. Requirements for the use of cast irons with an elongation after fracture equal or less than 15 % are given in EN 15776.
