6、和定义;—调整了标准的编排结构，即将原标准第3章“试验方法和验收规则”分为“试验方法”和“检验规则”两章，将其中的技术要求集中于本标准的第6章“要求”内;—明确了按额定起道力和额定拨道力编写产品型号;—产品规格由一种增加到五种;—删除了有关工艺方面的要求，增加了铸件和焊接质量以及安全性能方面的要求，并规定进行逐台检验;—取消了容积效率计算和高温密封性能检查;—将保压性能由抽样检验改为逐台检验;—在型式检验项目中增加了超载检验。本标准由铁道部标准计量研究所提出并归口。本标准起草单位:哈尔滨铁路局、铁道科学研究院铁道建筑研究所、牡丹江铁路机具配

7、件有限责任公司(原林口液压起拨道器厂)。本标准主要起草人:程勉海、付廷龙、宋慧京、韩忠福。本标准于1987年首次发布，本次为第一次修订。TB/If1925-2003液压起拨道器通用技术条件，范围本标准规定了液压起拨道器(以下简称起拨道器)的有关术语和定义、型号编制、主要参数及安全使用限界、要求、试验方法、检验规则、标志和包装。本标准适用于铁路轨道作业用的液压起拨道器。2规范性引用文件下列文件中的条款通过本标准的引用而成为本标准的条款。凡是注日期的引用文件，其随后所有的修改单(不包括勘误的内容)或修订版均不适用于本标准，然而，鼓励根据本标准达
