本文件规定了由非合金优质钢制成的具有规定室温性能的圆形截面电焊管和埋弧焊管的TR1和TR2质量交货技术条件。 注1:质量TR2旨在支持欧盟指令2014/68/EU的基本要求 具有规定室温特性的压力设备的温度（见表5）。 注2:一旦本标准在《欧盟官方公报》（OJEU）上发布，对符合2014/68/EU指令基本安全要求（ESR）的推定仅限于本标准中材料的技术数据，并不假定材料适用于特定压力设备。 因此，本材料标准中规定的技术数据与特定设备设计要求的对比评估，以验证是否满足压力设备指令的ESRs，需要由压力设备的设计师或制造商进行，还应考虑可能影响基材性能的任何后续加工程序。交叉引用:EN ISO 4885CEN/TR 10261EN 10027-1EN ISO 14284EN 10266EN 10220EN ISO 148-1:2016EN 10027-2EN 10020EN ISO 10893-2:2011EN 10204:2004EN ISO 10893-3:2011EN ISO 8493:2004EN ISO 2566-1:1999EN ISO 6892-1:2016ISO 11484:2009EN ISO 377:2017EN ISO 5173: 2010EN 10168:2004EN ISO 10893-7:2011EN ISO 10893-1:2011EN ISO 10893-11:2011EN ISO 17639:2013EN 10021:2006EN ISO 10893-10:2011EN ISO 8492:2013EN ISO 14174:2012EN ISO 10893-6:2011EN ISO 9712:2012购买本文件时提供的所有当前修订版均包括在内。

This document specifies the technical delivery conditions for qualities TR1 and TR2 of electric welded and submerged arc welded tubes of circular cross section, with specified room temperature properties, made from non-alloy quality steel. NOTE 1 Quality TR2 is intended to support the essential requirements of EU Directive 2014/68/EU in respect of pressure equipment with specified room temperature properties (see Table 5). NOTE 2 Once this standard is published in the Official Journal of the European Union (OJEU), presumption of conformity to the Essential Safety Requirements (ESR) of Directive 2014/68/EU is limited to the technical data for the materials in this standard and does not presume adequacy of the material for a specific item of pressure equipment. Consequently, the assessment of the technical data stated in this material standard against the design requirements of a 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 any subsequent processing procedures which may affect properties of the base materials.Cross References:EN ISO 4885CEN/TR 10261EN 10027-1EN ISO 14284EN 10266EN 10220EN ISO 148-1:2016EN 10027-2EN 10020EN ISO 10893-2:2011EN 10204:2004EN ISO 10893-3:2011EN ISO 8493:2004EN ISO 2566-1:1999EN ISO 6892-1:2016ISO 11484:2009EN ISO 377:2017EN ISO 5173:2010EN 10168:2004EN ISO 10893-7:2011EN ISO 10893-1:2011EN ISO 10893-11:2011EN ISO 17639:2013EN 10021:2006EN ISO 10893-10:2011EN ISO 8492:2013EN ISO 14174:2012EN ISO 10893-6:2011EN ISO 9712:2012All current amendments available at time of purchase are included with the purchase of this document.
