	Visual inspection	—	The indicator flag should not burn on any of the three specimens. Nor should the cotton be ignited by ignited or burning particles or by ignited drops.
Soldering heat resistance		—	Pass (Only for sleeve with nominal inner diameter ≤ 5 mm)
Volatile content	Low content level	%	—			≤1.0		≤0.7
	Other level					≤1.5		≤1.5
Bending after heating		—	The coating has no visible cracks or peeling off, allowing the color to become darker (test temperature: 180±3℃)
Bending at low temperatures		—	The coating has no visible cracks or peeling off (test temperature: ≤-70～5℃)
Hydrolysis resistance of paint layer		—	There is no migration of the coating, no adhesion between the hose and the paper and the hose test piece, and no discoloration of the paper.
Shelf life		—	6 months
