Rubber and plastics hoses and hose assemblies for automotive air conditioning. Specification - Refrigerant 134a Ingestion-build-47553 By using BS EN 61249-2-301 Scope 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
