标准范围
ISO 10502:2012规定了飞机液压、燃油和润滑油系统中使用的聚四氟乙烯(PTFE)软管组件的要求,其温度在-55°C(-67°F)和232°C(450°F)之间(对于I类组件),以及-55°C(-67°F)和135°C(275°F)之间(对于II类组件),标称压力高达10500 kPa(1523 psi)(105巴)。软管组件也适用于在航空航天气动系统中相同的温度和压力限制下使用,其中允许一些气体通过PTFE衬里壁扩散。ISO 10502:2012涵盖了以下等级的软管组件:·I类:配有耐腐蚀钢或钛零件配件的软管组件[232°C(450°F)];·II类:配有耐腐蚀钢和铝配件[135°C(275°F)]、DN12及以上的软管组件。
ISO 10502:2012 specifies requirements for polytetrafluoroethylene (PTFE) hose assemblies for use in aircraft hydraulic, fuel and lubricating oil systems at temperatures between -55 °C (-67 °F) and 232 °C (450 °F) for Class I assemblies and between -55 °C (-67 °F) and 135 °C (275 °F) for Class II assemblies, and at nominal pressures up to 10 500 kPa (1 523 psi) (105 bar). The hose assemblies are also suitable for use within the same temperature and pressure limitations in aerospace pneumatic systems where some gaseous diffusion through the wall of the PTFE liner is tolerated.ISO 10502:2012 covers hose assemblies of the following classes:· class I: hose assemblies with fitting of corrosion-resistant steel or titanium parts [232 °C (450 °F)];· class II: hose assemblies with fitting of corrosion-resistant steel and aluminium parts [135 °C (275 °F)], DN12 and larger.
