6、格由一種增加到五種;—刪除了有關工藝方面的要求，增加了鑄件和焊接質量以及安全性能方面的要求，并規(guī)定進行逐臺檢驗;—取消了容積效率計算和高溫密封性能檢查;—將保壓性能由抽樣檢驗改為逐臺檢驗;—在型式檢驗項目中增加了超載檢驗。本標準由鐵道部標準計量研究所提出并歸口。本標準起草單位:哈爾濱鐵路局、鐵道科學研究院鐵道建筑研究所、牡丹江鐵路機具配件有限責任公司(原林口液壓起撥道器廠)。本標準主要起草人:程勉海、付廷龍、宋慧京、韓忠福。本標準于1987年首次發(fā)布，本次為第一次修訂。www.bzfxw.comTB/If1925-2003液壓起撥道器通用技術條件，范圍本標準規(guī)定了液壓起撥道器(以下簡稱起撥道
7、器)的有關術語和定義、型號編制、主要參數(shù)及安全使用限界、要求、試驗方法、檢驗規(guī)則、標志和包裝。本標準適用于鐵路軌道作業(yè)用的液壓起撥道器。2規(guī)范性引用文件下列文件中的條款通過本標準的引用而成為本標準的條款。凡是注日期的引用文件，其隨后所有的修改單(不包括勘誤的內容)或修訂版均不適用于本標準，然而，鼓勵根據(jù)本標準達成協(xié)議的各方研究是否可使用這些文件的最新版本。凡是不注日期的引用文件，其最新版本適用于本標準。GB/
