英文名称：Rubber and plastics hoses and hose assemblies for automotive air conditioning — Specification — Part 3: Refrigerant 1234yf

标准范围
This document specifies the requirements for rubber or thermoplastic hoses and hose assemblies
used for circulating liquid and gaseous R1234yf (tetrafluoropropene) 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 has been laid down.
