BS EN 13674-1:2011+A1:2017规定了46 kg/m和更大线性质量的Vignole铁路钢轨，用于常规铁路 以及高速铁路轨道的使用。规定了九个珠光体钢等级，硬度范围为200 HBW至440 HBW，包括非 热处理非合金钢、非热处理合金钢、热处理非合金钢和热处理 合金钢。本标准规定了23种钢轨断面。规定了两类钢轨平直度，对平直度、表面平整度和弯曲度的要求不同 皇冠侧面图。规定了两类轮廓公差。交叉引用:ISO 6892-1:2009 Ed 1ISO 12108:2012ISO 6506-1:2005 Ed 2ISO 1099:2017ISO 4968ISO 14284:1996（R06）EN ISO 14284（ISO 14284:1996 AS）EN ISO 6506- 1（ISO 6506-1:2014）ASEN 10163-1:2004ASTM E399-12e3CEN/TR 10261:2013EN 10276-1:2000EN ISO 6892-1（ISO 6892-1:2016）EN 10027-2:2015ISO 9001:2008EN ISO 9001（ISO 9001:2015）ASEN 10027-1:2016包含以下内容:2017年11月修订

BS EN 13674-1:2011+A1:2017 specifies Vignole railway rails of 46 kg/m and greater linear mass, for conventional and high speed railway track usage.Nine pearlitic steel grades are specified covering a hardness range of 200 HBW to 440 HBW and include non heat treated non alloy steels, non heat treated alloy steels, and heat treated non alloy steels and heat treated alloy steels.There are 23 rail profiles specified in this standard.Two classes of rail straightness are specified, differing in requirements for straightness, surface flatness and crown profile. Two classes of profile tolerances are specified.Cross References:ISO 6892-1:2009 Ed 1ISO 12108:2012ISO 6506-1:2005 Ed 2ISO 1099:2017ISO 4968ISO 14284:1996 (R06)EN ISO 14284 (ISO 14284:1996 AS)EN ISO 6506-1 (ISO 6506-1:2014) ASEN 10163-1:2004ASTM E399 - 12e3CEN/TR 10261:2013EN 10276-1:2000EN ISO 6892-1 (ISO 6892-1:2016)EN 10027-2:2015ISO 9001:2008EN ISO 9001 (ISO 9001:2015) ASEN 10027-1:2016Incorporates the following:Amendment, November 2017
