Abstract A method and an apparatus for the determination of the filling capacity of tobacco and the hardness of cigarettes are described. Tobacco (R) in a container (30) is compressed by a test plunger (8) driven in a pre-set manner by a motor (18), such that the force exerted on the tobacco (R) is measured and passed to a computer (44) as is the measured length of the tobacco column. After the end of the compression movement the test plunger (8) rests in its end position for a relaxation period, and the force acting on the tobacco (R) is measured at pre-set time intervals and passed on to the computer (44). The temperature and the moisture of the tobacco (R) are determined in the apparatus during the implementation of the method, and these allow the measured values to be adjusted to reflect standard conditions. The apparatus for determining the hardness of cigarettes differs from the apparatus for the determination of the filling capacity of tobacco only in the construction of the test plunger and the sample holder. Both methods proceed in the same way. (Figure 2)
