摘要:: 本文结合世界典型质量案例，从产品认知领域、标准执行情况和不合格品处置三个角度对我国高速铁路道岔制造和服役阶段的质量状态进行思考。分析认为：（1）我国高速铁路道岔服役十多年来，陆续反馈的质量信息有利于不断拓展认知领域和优化道岔设计；（2）高速铁路道岔标准是行业内道岔理论设计和实践经验的宝贵总结，是保障道岔产品质量的基本准则；（3）产品质量不符合规定是否影响使用应由产品设计或标准制定单位及用户判断；（4）从长远考虑，杜绝不合格品对促进道岔行业制造水准的整体提升和精品质量意识的转型是有利的，对进一步保障道岔产品质量是有利的。

Abstract:: Combining with the classical quality cases around the world, this paper analyzes the quality conditions of high-speed railway turnouts in China in fabrication and service from three aspects: product cognition, compliance, and disposal of nonconforming products. The results show that: (1) The quality feedback about the high-speed railway turnouts from time to time in more than ten years of their services in China is conducive to expanding the cognition and optimizing the design of turnouts. (2) The high-speed railway turnout standard is a valuable summary of the theoretical design and engineering practice of turnouts in the industry, and it is the basic criterion to ensure the quality of turnout products. (3) It is the responsibility of the product designers or the standard makers and the users to judge whether the nonconforming products affect the use. (4) From a long-term perspective, eliminating nonconforming products is beneficial to promote the overall improvement of fabrication standards and the transformation of quality consciousness of high-quality products in turnout industry, and to further guarantee the quality of turnout products.
