2.1 The mass of aerosol forming composition in
each type generator should be specified by the manufacturer.
2.2 The gross weight of each type generator should
be determined by weighing on a laboratory scale.
2.3 An average of five generators should be discharged
in an appropriate facility. After the generators have cooled, the
average net weight of the empty generators should be determined using
the same laboratory scale used in paragraph 2.2 above.
