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壓力用無縫鋼管——交貨技術條件——第1部分：具有規定室溫性能的非合金鋼管。

1.Scope範圍

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.

本歐洲標準規定了由非合金優質鋼製成的具有指定室溫性能的圓形橫截麵無縫管TR1和TR2的兩種質量的交貨技術條件。

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：一旦本標準根據指令97/23/EC在歐盟官方公報（OJEU）上發布，對符合指令97/23/EC基本安全要求（ESR）的推定僅限於本標準中材料的技術數據，並不推定材料對特定設備項目的充分性。因此，壓力設備的設計者或製造商需要根據該特定設備的設計要求對本材料標準中規定的技術數據進行評估，以驗證是否滿足《壓力設備指令》的ESR，同時考慮到可能影響基材性能的後續製造工藝。
