GB/T 20023-2005 "Rubber and/or plastics hoses and hose assemblies for airless spraying" specifies the technical requirements for four types of hoses and hose assemblies used in airless spraying, applicable to solvent-based paint spraying scenarios. They are classified based on design working pressure (20MPa or 36MPa) and operating temperature (-20°C to 50°C or -20°C to 80°C). Key performance indicators that require testing include burst pressure, ultraviolet resistance, and interlayer adhesion strength. Testing requires instruments such as static hydraulic test machines, ultraviolet aging chambers, and tensile testing machines to ensure the safety and stability of spraying operations.
