Potassium hydroxide for industrial use — Determination of carbon dioxide content — Titrimetric metho...
Applicable to products having CO2 contents of more than 0.01 % (m/m). Three cases are envisaged. The product containing neither sulphides nor chlorates or containing sulphides or chlorates. The principle in presence of neither sulphides nor chlorates consists in liberation of carbon dioxide in a flow of gas and absorption in an excess of standard volumetric barium hydroxide solution. Titration of…
Liquid halogenated hydrocarbons for industrial use — Sampling
These methods are applicable to products not contaminated by an axtraneous phase (for example, water). Accidental pollution is also considered. Three cases are considered: small containers, large containers and continuous sampling. The procedure consists in formation of a blended bulk sample, representing the whole of the batch, by mixing several samples. The number and the method of taking of…

Dissolution of a test portion taken from the laboratory sample, previosly ground and sifted. Addition of formaldehyde to transform any ammonium ions present into hexamethylenetetramine and of the disodium salt of ethylenediamin tetra-acetic acid to complex any extraneous cations present which could cause excessive errors. These additions have no detrimental effect on the precision or…
