3 Overview
The Tobacco Special Moisture Resistance Standard Rod is a standard appliance used on tobacco special resistance testers. Tobacco special resistance standard
The rod test is based on the gas flow rate of (17.5 ± 0.3) mL/s, the special resistance rod for tobacco in the gas path
The measurement of the pressure difference at the end is performed, and the verification value of the standard rod for the special suction resistance of tobacco is calculated.
The verification device is mainly composed of a dedicated constant current generating device, a special fixture and a differential pressure gauge. Dedicated constant current generation
The piston can be driven or the critical flow hole can be driven.
4 terms
The following terms apply to this verification procedure.
4.1 Tobacco resistance of the special resistance coefficient of tobacco
Under standard conditions, when a steady flow of 17.5 mL/s flows through the tobacco-specific resistance standard rod,
The pressure difference between the two ends is the suction resistance of the tobacco special resistance resistance standard rod.
4.2 Piston drive
The piston moves in a high-precision perforated cylindrical cylinder at a constant speed, driven by a high-precision motor, from the ambient atmosphere.
The air is pumped to form a gas flow with a stable volume flow.
4.3 Critical flow hole drive
A pressure difference is formed at both ends of the critical flow hole, and the gas forms a gas flow through the flow hole under the pressure difference, when the pressure
When the difference reaches the critical flow hole critical pressure condition, the flow hole produces a constant flow of air (tobacco-specific critical flow)
The pores, under critical pressure conditions, produced a constant flow of 17.5 mL/s.
