Hexafluorosilicic acid for industrial use — Determination of available fluorine content — Potentiome...
Covers a method consisting in separating the fluorine from a test portion by distillation in the presence of perchloric acid, followed by potentiometric titration of the distillate with lanthanum nitrate solution using a fluoride ion-selective electrode. Is applicable to products having total available fluorine contents in the range between 15 and 35 % (m/m).
Timber structures — Joints made with mechanical fasteners — General principles for the determination...
Applies to joints made with mechanical fasteners used in statically loaded timber structures. Covers the conditioning of test specimens and explains the apparatus to be used for measuring the geometry of the test specimens, their moisture content and other characteristics. Details the loading procedure and specifies the details to be included in the test report.
Road vehicles — World manufacturer identifier (WMI) code
Specifies the content and structure of an identifier in order to establish, on a world-wide basis, the identification of road vehicle manufacturers. This identifier is the first section of the vehicle identification number (VIN) described in ISO 3779. Applies to motor vehicles, trailers, motorcycles, and mopeds as defined in ISO 3833. This second edition cancels and replaces the first edition (…
Rubber latex — Styrene-butadiene — Determination of bound styrene content
Specifies a method for the determination of the bound styrene content of styrene-butadiene rubber (SBR) latices. Applicable to hot emulsion polymerized SBR latices having a bound styrene content of up to 55 % and to cold emulsion polymerized SBR latices having a bound styrene content between 18 and 40 %. This second edition cancels and replaces the first edition (1975).
Packaging — Sacks — Conditioning for testing — Part 1: Paper sacks
The principle consists in exposure of empty sacks to a conditioning atmosphere so that a state of temperature and moisture content equilibrium is reached between the sacks and this atmosphere. Conditioning atmospheres ar described by a table. Equipment, procedure and test report are specified.
Chlorofluorinated hydrocarbons — Determination of water content — Gravimetric method
Covers a method applicable to products having water contents in the range between 2 and 100 mg/kg. Uses a principle consisting in the passage of a vaporized test portion through two weighed absoprtion tubes containing a phosphorus(V) oxide absorption mixture, and calculation of the water content from the increase in mass of the absorption tubes.
