Composite standard rod for cigarette and filter rod metering, comprehensive test system and test method

The invention provides a composite standard rod for cigarette and filter rod metering. The composite standard rod comprises a draw resistance/ventilation laminar flow module, a cylindrical shell, a standard circumferential outer circular ring, a hardness measuring circular ring and a non-contact communication module, an axial through hole is formed in the cylindrical shell, and air holes are formed in the two ends of the cylindrical shell respectively. The suction resistance/ventilation laminar flow module is hermetically filled in the axial through hole through the peripheral surface, an axially through capillary tube is arranged in the suction resistance/ventilation laminar flow module, the side part of the suction resistance/ventilation laminar flow module is provided with a ventilation hole communicated with the capillary tube, and the cylindrical shell is provided with a corresponding annular air passage corresponding to the ventilation hole; the standard circumferential outer circular ring and the hardn
