Magnesium alloys — Determination of thorium — Part 2: Titrimetric method
The method is applicable to products having thorium contents between 0,2 and 5,0 % (m/m). Specifies principle, reagents, apparatus, sampling, procedure, expression of results and test report.
Road vehicles — World parts manufacturer identifier (WPMI) code
Specifies the content and structure of an identifier in order to establish, on a world-wide basis, the identification of the manufacturers of parts for road vehicles; this identifier may serve, at the manufacturer's option, as a substitute or an addition for various national or international systems which already exist. Applies only to manufacturers of parts to be used on road vehicles as…
Magnesium alloys — Determination of thorium — Part 1: Gravimetric method
The method is applicable to products having thorium contents between 0,2 and 5,0 % (m/m). Specifies principle, reagents, apparatus, sampling, procedure, expression of results and test report.
Carbonaceous materials for the production of aluminium — Pitch for electrodes — Determination of con...
Specifies a gravimetric method, the principle of which consists in weighing the fraction of a test portion of pitch which is insoluble in toluene after boiling for a specified period.
The Standard specifies certain characteristics of the oil. The oil shall be clear and almost colourless to pale yellow, the odour characteristic, recalling cineole. The relative density at 20/20 °C has to ly between 0,906 and 0,925 and the refractive index at 20 °C between 1,4590 and 1,4670. The optical rotation shall range from 0 to + 10 . 1 volume of the oil shall not require more than 5…
Maize — Determination of moisture content (on milled grains and on whole grains)
A section one specifies the reference method. It consists in grinding of sample, if necessery, after pre-conditioning, if required, then drying of a test portion at a temperature between 130 and 133 C under conditions which enable a result to be obtained which is in agreement with that obtained by the absolute method ( prescribed in an annex). A section two specifies the routine method on whole…
Boric acid, boric oxide, disodium tetraborates and crude sodium borates for industrial use — Determi...
Specifies a method applicable to products in which the nickel content being determined exceeds 0,1 mg/kg. The principle of determination is based on dissolution of a test portion, formation of the coloured nickel furil -dioxime complex, extraction with chloroform and photometric measurement at a wavelength of about 435 nm.
Crude sodium borates for industrial use — Determination of alkali-soluble copper and manganese conte...
Describes a method applicable to products in which the alkalisoluble copper and manganese contents excess 0,25 and 0,5 mg/kg, respectively. The principle consists in successively determining the manganese and copper contents of the two coloured complexes obtained during the analysis, followed by photometric measurements at wavelengths of about 435 nm and 450 nm, respectively.
Crude sodium borates for industrial use — Determination of carbonate content — Gravimetric method
Covers a method based on reaction of the carbonate in a test portion with hydrochloric acid, absorption of the released carbon dioxide in soda asbestos and measurement of the increase in mass.
