	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)
Bending after heating			The coating has no visible cracks or peeling off, allowing the color to
		–	become darker (test temperature: 180±3℃)
			The coating has no visible cracks or peeling off (test temperature: ≤-15～
Bending at low temperatures		–	-18℃)
Hydrolysis resistance of paint			There is no migration of the coating, no adhesion between the hose and
layer		–	the paper and the hose test piece, and no discoloration of the paper.
Shelf life		–	12 months
