Scope

Covers a method permitting measurement of temperature differences of 0,5 °C. Should not be considered as an analytical method, but as a test for identification and indication of the purity of a product. Is based on evaporation by boiling of a known volume of the product under test and measurement of the temperatures corresponding to the evaporation of 5 and 95 % of the initial volume of the liquid.
