Title:Hose Assembly, Polytetrafluoroethylene (Ptfe), Up to 232 Degrees C and 10 500 Kpa Procurement Specification, Metric (Iso/Dis 10502)
Issuing Committee:G-3, Aerospace Couplings, Fittings, Hose, Tubing Assemblies
Scope: This Metric Aerospace Standard (MA) covers the requirements for polytetrafluoroethylene (PTFE) hose assemblies for use in aerospace hydraulic, fuel, and lubricating oil systems at temperatures between -55掳C and 232掳C for Class I assemblies, -55掳C and 135掳C for Class II assemblies, and at nominal pressures up to 10 500 kPa (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 can be tolerated.The use of these hose assemblies in pneumatic storage systems is not recommended. In addition, installations in which the limits specified herein are exceeded, or in which the application is not covered specifically by this standard, for example oxygen, shall be subject to the approval of the purchaser.【英文标准名称】:Portablefireextinguishers-Part1:Description,durationofoperation,classAandBfiretest;GermanversionEN3-1:1996
