ISO/TC 45/SC 1 Rubber and plastics hoses and hose assemblies
International Standard
This part of ISO 8066 specifies the requirements for rubber or thermoplastic hoses and hose assemblies used for
circulating liquid and gaseous R134a (tetrafluoroethane) in the air-conditioning systems of automobiles. The hoses
and hose assemblies are designed in such a way as to restrict losses of refrigerant and contamination of the
system. The operational temperature range is _ 40 °C to +125 °C.
Due to the critical relationship between the hose and coupling for this application, a requirement that the coupling
to be used in service be used for testing is laid down.
