T/QCKT 003-2011 Aluminum-made air conditioning pipes and components for automobiles
Basic Information
Scope
Scope: This standard specifies the technical requirements, test methods, inspection rules, marking, packaging, transportation, and storage for aluminum air conditioning pipes and assemblies used to transport liquid or gaseous refrigerants in automotive air conditioning systems. This standard applies to aluminum air conditioning pipes and assemblies used to transport liquid or gaseous refrigerants in automotive air conditioning systems. The design of aluminum air conditioning pipes should minimize refrigerant leakage and environmental pollution, and they should be suitable for use in a temperature range of -40°C to +125°C. Main technical contents: dimensions, inner and outer diameters of aluminum pipes, wall thickness of aluminum pipes, surface quality, leakage amount, air tightness, high temperature resistance, low temperature resistance, bursting pressure, pressure resistance, internal surface cleanliness, pulse fatigue resistance, and corrosion resistance.
