If it is still rejected, this Item shall be judged as rejected. 5.5.9 Other formulations of products They shall be tested according to the test methods in relevant national standards. 5.6 Smoke dust The smoke dust shall be tested according to the method specified in GB/T 28015. 5.7 Minimum effective period of liquid vaporizer It is tested in the temperature of (23±3)℃, with relative humidity of (65±15)%, and no strong convection air. (Test angle) unscrew the bottle cap of the liquid vaporizer, conduct the test by electrifying continuously (the liquid bottle is connected with a matching electric heater), and perform visual inspection until reaching the indicated minimum effective period, and observe whether the liquid contained in the bottle is in contact with the core rod to ensure that the product can be used longer than the minimum effective period. Test at least 3 bottles in parallel, and take the average of the effective period.
