BS EN 16771:2016定义了铝热剂的实验室试验和批准要求 使用车间条件下产生的焊缝的焊接工艺。它适用于EN 14811中所述的相同型材和钢材的新槽钢轨的连接 等级本标准不包括结构型材和机加工型材的焊接。遵守本标准的要求本身并不能确保 轨道和交通特定条件下的焊接工艺。本标准不包括不同钢轨段、磨损钢轨或不同钢轨之间的焊缝 分数。除明确要求外，本标准还要求第4条中详述的项目 记录在案。为了符合本标准，重要的是 应满足要求和记录的项目。 交叉引用:EN 14811EN ISO 6506-1ISO 6506-1EN ISO 6507-1ISO 6507-1EN ISO 9712ISO 9712EN ISO 7500-1ISO 7500-1购买本文件时可使用的所有现行修订版均包含在购买本文件中。

BS EN 16771:2016 defines the laboratory tests and requirements for approval of an aluminothermic welding process using welds produced in workshop conditions.It applies to the joining of new, grooved rails as described in EN 14811 of the same profile and steel grade. Welding of construction profiles and machined profiles are not covered in this standard.Compliance with the requirements of this standard does not in itself ensure the suitability of a welding process for specific conditions of track and traffic.The standard does not cover welds made between different rail sections, worn rails or different rail grades.In addition to the definitive requirements, this standard also requires the items detailed in Clause 4 to be documented. For compliance with this standard, it is important that both the definitive requirements and the documented items be satisfied.Cross References:EN 14811EN ISO 6506-1ISO 6506-1EN ISO 6507-1ISO 6507-1EN ISO 9712ISO 9712EN ISO 7500-1ISO 7500-1All current amendments available at time of purchase are included with the purchase of this document.
