No.	Test project	Test method	Test requirements
1	gloss	Glossmeter (60 °)	≥50
2	hardness	pencil hardness	≥8H
3	adhesion	Hundred grid method	≤ Level 2
4	acid resistance	Soaking in 5% acetic acid solution for 24 hours	The coating has no abnormalities
5	alkali resistance	Soak in 5% sodium carbonate solution for 24 hours	The coating has no abnormalities
6	salt tolerance	5% saline water micro boiling for 24 hours	The coating has no abnormalities
7	LGA abrasion resistance	The bottom of the pot is divided into 4 areas, and 3 of them are protected with special tape. Steel balls, white corundum, and water are added, and the total amount is determined according to the diameter of the pot bottom. Shake on a shaker. Every 15 minutes of shaking, peel off the protective tape of one area in sequence for a total of 45 minutes.	≤ 3 points
8	heat resistance	Insulate at 300 ℃ for half an hour, then immerse in water for rapid cooling, and ensure that the coating has no abnormalities such as cracking or peeling	≥ 10 cycles
9	Non sticky	Keep at 350 ℃ for half an hour, then fry 10 eggs at 180-190 ℃ for one testing cycle	≥ 5 cycles
