Acetic acid for industrial use — Method of test — Part 2: Determination of acetic acid content — Tit...
The principle consists in titration of a test portion with standard volumetric sodium hydroxide solution, using phenolphthalein as indicator. Calculation of the acid content, making allowance for any formic acid present, determined separately (see ISO 753/3). This International Standard has also been approved by the International Union of Pure and Applied Chemistry (IUPAC). International…

Butadiene for industrial use — Determination of hydrocarbon impurities — gas chromatographic method
Covers a method based on the selection of a gas chromatography column allowing the separation of the impurities to be determined. A gaseous test portion is passed through this column and the peaks obtained are detected by flame ionization and compared with those derived from an external standard. Columns and operating conditions having been found suitable for such a test are indicated in Annex A…
