2Scope / Description

In the case of anhydous salts, the weighing of the test portion is carried out directly into platinum crucible. Transfering of the crucible in a muffle furnace, maintained at (900 +- 50) ?C. In case of hydrated sals, the weighing is also carried out directly; the test porion is previously heated in the flame of a Bunsen burner. Covering and placing of the crucible so that the Bunsen flame plys on its lid. Subsequent transfer of the covered crucible to the muffle furnace.
