EN 10216-1 Seamless steel tubes for pressure purposes - Technical delivery conditions - Part 1: Non-alloy steel tubes with specified room temperature properties.

EN 10216-1压力用无缝钢管——交货技术条件——第1部分：具有规定室温性能的非合金钢管。

1.Scope范围

This European Standard specifies the technical delivery conditions for two qualities TR1 and TR2 of seamless tubes of circular cross section with specified room temperature properties made of non-alloy quality steel.

本欧洲标准规定了由非合金优质钢制成的具有指定室温性能的圆形横截面无缝管TR1和TR2的两种质量的交货技术条件。

NOTE:Once this standard is published in the Official Journal of the European Union (OJEU) under Directive 97/23/EC, presumption of conformity to the Essential Safety Requirements (ESR) of Directive 97/23/EC is limited to technical data of materials in this standard 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 the Pressure Equipment Directive are satisfied,needs to be done by the designer or manufacturer of the pressure equipment, taking also into account the subsequent manufacturing processes which may affect properties of the base materials.

注：一旦本标准根据指令97/23/EC在欧盟官方公报（OJEU）上发布，对符合指令97/23/EC基本安全要求（ESR）的推定仅限于本标准中材料的技术数据，并不推定材料对特定设备项目的充分性。因此，压力设备的设计者或制造商需要根据该特定设备的设计要求对本材料标准中规定的技术数据进行评估，以验证是否满足《压力设备指令》的ESR，同时考虑到可能影响基材性能的后续制造工艺。
