Tobacco and tobacco products — Determination of alkaloid content — Spectrometric method
Specifies a reference method for the determination of alkaloids, expressed as nicotine. The method is applicable to unmanufactured tobacco, manufactured tobacco and tobacco products. It is based on submission of the sample to steam distillation, spectrometric measurement of the absorption of the distillate and calculation of the percentage content of nicotine.
Air cargo equipment — Base-restrained certified containers exclusively for the lower deck of high-ca...
Covers the design, fabrication, performance and testing requirements for the containers. Basic functions of containers are the unitization of baggage, cargo or mail during ground handling and transportation, and the restraint of its contents in flight.
Rubber — Determination of total sulfur content — Part 1: Oxygen combustion flask method
Is applicable to NR, CR, SBR, BR, IR, IIR, EPDM, NBR, and ebonite (see ISO 1629). The principle of the method is oxidation by ignition in an atmosphere of oxygen in the presence of hydrogen peroxide, conversion of sulfur to sulfuric acid, and determination of the sulfate by titration with barium perchlorate. The method is applicable for the determination of all the sulfur present in a rubber or…
Rubber — Determination of total sulfur content — Part 2: Sodium peroxide fusion method
Is applicable to NR, CR, SBR, BR, IR, IIR, EPDM, NBR, and ebonite (see ISO 1629). The principle of the method is oxidation with sodium peroxide, conversion of sulfur to sulfate ions, and determination of the sulfate by gravimetric analysis as barium sulfate. The method is applicable for the determination of all the sulfur present in a rubber or rubber product, including that contained in barium…
Safety of household and similar electrical appliances - Part 2: Particular requirements for dishwash...
Deals with the safety of electric dishwashers for household use which are intended for washing and rinsing dishes, cutlery and other utensils, their rated voltage being not more then 250 V for single-phase appliances and 480 V for other appliances. The contents of the interpretation sheet of June 1996 and the corrigendum of July 1999 have been included in this copy.
Fertilizers — Determination of bulk density (loose) of fine-grained fertilizers
The method is applicable to fertilizers, dry only, which contain a large proportion of particles of diameters less than 0,5 mm. Its principle is pouring the fertilizer from a specified filling device into a specified measuring cylinder of known volume and weighing the contents of the cylinder. If the fertilizer has absorbed moisture during transport or storage, it is necessary to dry it in an…
