本欧洲标准规定了表1规定的可焊接细晶粒钢制成的压力设备的平板产品要求。 注1:根据EN ISO 643测试，精细晶粒钢被理解为铁素体晶粒尺寸为6或更细的钢。 EN 10028-1:2017的要求和定义也适用。 注2:根据“2014/68/EU指令”，在欧盟官方公报（OJEU）发布此欧洲标准之后，符合2014/68/EU指令的基本安全要求（ESR）的推定仅限于材料的技术数据本欧洲标准（第1部分和系列的其他相关部分），并且不将材料的适当性推定到特定设备项目。因此，需要对本材料标准中规定的技术数据对本设备的设计要求进行评估，以验证2014/68/EU指令的ESR是否得到满足。

This European Standard specifies requirements for flat products for pressure equipment made of weldable fine grain steels as specified in Table 1. NOTE 1 Fine grain steels are understood as steels with a ferritic grain size of 6 or finer when tested in accordance with EN ISO 643. The requirements and definitions of EN 10028-1:2017 also apply. NOTE 2 Once this European Standard is published in the EU Official Journal (OJEU) under Directive 2014/68/EU, presumption of conformity to the Essential Safety Requirements (ESRs) of Directive 2014/68/EU is limited to technical data of materials in this European Standard (Part 1 and the other relevant part of the series) and does not presume adequacy of the material to a specific item of equipment. Consequently, the assessment of the technical data stated in this material standard against the design requirements of this specific item of equipment to verify that the ESRs of Directive 2014/68/EU are satisfied, needs to be done.
