The suitable calorimeter is composed as follows (see the enclosure hereto attached):

a) - Container of dissolution, composed of: an insulated flask (1) (i.e. Dewar flask)

placed in a thermo - insulated case (2) inside a container (3) of isolated material (i.e.

wood, plastic) or submerged in a thermostatic bath regulated at: ± 0.2°C;

- an insulating cap (4) (i.e. cork or plastic) with holes suitable for the location of the ther-

mometer ( 5), the stirrer and the funnel (7) used to put the specimen into the case (2).

The calorimeter's insulation (9) must ensure that the coefficient of thermal loses k (de-

termined in accordance with the instructions at point 6.3) is smaller of 0,06 Kelvin for 15

minutes for each Kelvin degree above the environment temperature.
