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…
Chromate conversion coatings on electroplated zinc and cadmium coatings
Specifies requirements relating to coatings intended to give protection against corrosion. Finishes for giving particular colours only or specifically to improve paint adhesion are not covered by this International Standard. Gives furhermore the method of application of chromate conversion coatings and a classification.
Cinematography — Projection reels/spools 75 to 312 mm diameter for 8 mm Type S motion-picture film —...
This International Standard specifies the dimensions for 8 mm Type S motion-picture projection reels/spools of 75 to 312 mm diameter (with the exception of the 75 mm Type No. 7) that are interchangeable on all types of reel-to-reel projection equipment. NOTE - The No. 7 reel (75 mm), although temporarily recognized, will be superseded by that specified in ISO 6033. lt is recommended that new…
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…

Propylene 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. Uses two types of columns, one for the determination of methane, ethane and acetylene (adsorption…
