Road vehicles — Low-speed serial data communication — Part 3: Vehicle area network (VAN)
Specifies the data link layer and the physical layer of the VAN, a communications network up to 125 kbit/s, for road vehicle application. The VAN is an access-method oriented multimaster-multislave which allows optimized request/response management by special method of handling a remote transmission request (retaining access to the medium to allow insertion of a response). Defines the general…

Iron ores — Determination of copper content — Part 1: 2,2'-Biquinolyl spectrophotometric method
The principle of the method specified is decomposition of the test portion by treatment with hydrochloric, nitric and perchloric acids, dehydration of silica, dilution and filtration, ignition of the residue, treatment with hydrofluoric and sulfuric acids, fusion with sodium carbonate, dissolution of the cooled melt in the filtrate, reduction of copper(II) to form the red-violet complex of copper…
Soil quality — Determination of mineral oil content — Method by infrared spectrometry and gas chroma...
Specifies two methods for the quantitative determination of mineral oil content in soil by IR spectrometry (method A) and gas chromatography (method B). Method A is applicable to mineral oil contents above 20 mg/kg on a dry matter basis, method B to those above 100 mg/kg. Petrol cannot be determined quantitatively with these methods, due to loss of volatile compounds during sample pretreatment.…
Iron ores — Determination of hygroscopic moisture in analytical samples — Gravimetric and Karl Fisch...
Specifies two methods for the determination of 0,05 % (m/m) to 6 % (m/m) of hygroscopic moisture content in test samples. Either method is used where the analytical value of the constituent to be calculated to a dry sample basis is higher than 10 % (m/m) in the following types of ores: processed ores containing metallic iron (direct reduced iron), natural or processed ores in which the sulfur…
The principle of the method specified is dissolving a test portion in hydrochloric and nitric acids and dilution of the solution to a known volume, introducing a known volume of the solution into an electrothermal atomizer of an atomic absorption spectrometer, measuring the atomic absorption of the 217,6 nm spectral resonance line energy emitted by an antimony lamp. The method is applicable to…
Steel and iron — Determination of manganese content — Flame atomic absorption spectrometric method
The principle of the method specified is dissolving a test portion in hydrochloric and nitric acids followed by evaporation with perchloric acid until white fumes appear, spraying the solution into an air-acetylene flame, spectrometrically measuring the atomic absorption of the 279,5 nm spectral line emitted by a manganese hollow cathode lamp. The method is applicable to manganese contents…
