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…

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…

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.

Specifies two methods for dry fertilizers only: the machine-tapping method and the hand-tapping method. Its principle is pouring the fertilizer from a specified funnel into a specified measuring cylinder of known volume, tapping the cylinder by means of a tapping machine or the walls of the cylinder by hand, and weighing the contents of the cylinder. If the fertilizer has absorbed moisture during…

The method is applicable to solid, but not powder fertilizers, dry only. It is not suitable for fertilizers which contain a large proportion of particles exceeding 5 mm in diameter. Its principle is pouring the fertilizer from a specified funnel into a specified measuring cylinder of known volume and weighing the contents of the cylinder. If the fertilizer has absorbed moisture during transport…

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…

The method specified is based on extraction by methanol, purification and enzymatic desulfatation, determination using reversed-phase chromatography. Does not determine glucosinolates which are substituted on the glucose molecule. A rapid method for the determination of glucosinolates content using X-ray fluorescence spectrometry is the subject of ISO 9167-2.

Defines the requirements for type BFOC/2,5 connector sets. Type BFOC/2,5 is a sub-family of single position optical connector sets. They are characterized by a bayonet coupling mechanism and a cylindrical ferrule of 2,5 mm typical diameter. The sub-family includes plug-adapter-plug and plug-socket configurations. The contents of the corrigendum of May 1996 have been included in this copy.

Under normal conditions of use, it does not apply to oilseeds which do not yield oil which is completely liquid at 20 °C (e.g. shea, palm, illipe, cocoa, etc.). The method has been successfully tested on the following oilseeds: rapeseed, soya, sunflower seed and groundnuts. The reference method for the determination of the oil content of oilseeds is specified in ISO 659.

Applies to the terminal markings for the main circuits of valve device stacks and assemblies and of factory assembled integrated convertor equipment. The terminal markings refer to stacks, assemblies and equipment comprising semiconductor valve devices. Specifies a logical alphanumeric marking system for the identification of the external terminals of the main power circuits in a stack, valve…
