标准范围

ISO 3949:2009规定了三种织物增强热塑性塑料软管和标称尺寸为3,2至25的软管组件的要求。根据导电性要求，每种类型分为两类。它们适用于在0°C至+60°C温度范围内使用ISO 6743-4中定义的水基液压油HFC、HFAE、HFAS和HFB，以及在-40°C至+100°C温度范围内使用ISO 6743-4中定义的油基液压油HH、HL、HM、HR和HV。ISO 3949:2009不包括端部配件的要求。它仅限于软管和软管组件的性能。

ISO 3949:2009 specifies requirements for three types of textile-reinforced thermoplastics hose and hose assembly of nominal size from 3,2 to 25. Each type is divided into two classes dependent on electrical conductivity requirements. They are suitable for use with water-based hydraulic fluids HFC, HFAE, HFAS and HFB as defined in ISO 6743？4 at temperatures ranging from 0 °C to +60 °C and oil-based hydraulic fluids HH, HL, HM, HR and HV as defined in ISO 6743-4 at temperatures ranging from -40 °C to +100 °C.ISO 3949:2009 does not include requirements for end fittings. It is limited to the performance of hoses and hose assemblies.
