First weigh the lighter without refueling, then refuel the tank to saturation and weigh it, then put it in a (70±2)°C indirect heating thermostat, keep it warm for 2 hours, then take it out and weigh it. The calculation formula is as follows: Scattering rate (%) -
Where: G--weight of lighter without refueling·g; G--weight of lighter after refueling to saturation, g; G--weight of lighter after heating and keeping warm, g. 6.3.3 Test of the gap between the steel wheel and the flint tube and the gap between the upper and lower shells G2-G3

After it is firmly attached, slowly pull off the adhesive tape to check whether the paint film falls off.
