GB/T 20025.3-2025 Rubber and plastics hoses and hose assemblies for automotive air conditioning—Specification—Part 3:Refrigerant 1234yf
Abstract
This document specifies the requirements for rubber or thermoplastic hoses and hose assemblies used to circulate the liquid and gas R1234yf (tetrafluoroethylene) in automotive air conditioning systems. The design of the hoses and hose assemblies is capable of limiting refrigerant loss and system contamination. The operating temperature range is -40°C to +125°C.
Since the connection between the hoses and fittings is crucial in applications, the requirements stipulate that the fittings used in the test should be the same as those used in actual operation.
