1 国际、国外液压标准化发展动向和行业现行标准水平国际标准化组织第131技术委员会(ISO/TC131)近几年的工作重点在于元件可靠性技术、污染控制技术和测量技术等方面,并且已经或正在组织制订大量的试验方法标准。比如:有关液压泵、液压阀(包括电液伺服阀)的污染敏感度测定方法;液压元件清洁度评定方法;密封装置密封性能评定方法;系统和元件产生压力脉动值的测定和噪声的测定方法;液
1 International and Overseas Hydraulic Standardization Development Trends and Industry Current Standards Standards The 131st Technical Committee of ISO (ISO / TC131) has been focusing on component reliability technology, pollution control technology and measurement technology in recent years and has been or is Organize a large number of test method standards. For example: hydraulic pumps, hydraulic valves (including electro-hydraulic servo valve) pollution susceptibility testing methods; hydraulic components cleanliness assessment methods; seal sealing performance evaluation methods; system and components to measure the pressure pulsation and noise measurement method ;liquid
