The constant airflow formed by the arch inhalation needs to pass through the cigarette at the end point according to the standard smoke airflow method. The ventilation of each part of the cigarette should be measured separately, and the required ventilation can be calculated.

Note: The tester only needs to pay attention to the increase in the test path of the air flow test. The test volume will be compared with the reading. 6.5 The instrument adopts a total air flow controller to ensure the test conditions. The full error of the total air flow should not exceed 0,10ml./, Note: The air flow rate must be determined by the air flow test method. The critical flow hole H is usually used to determine the air flow rate. 6.6 The test air flow rate should not cause uncertainty in the air flow rate (see 2). Sampling
