Oil of sandalwood — Determination of santalols content (in the form of their trimethylsilyl derivati...
A small quantity of the oil is analyzed under specified conditions. The santalols content is determined by using the internal standard method after their transformation into the corresponding trimethylsilyl ethers. Polyethylene glycol 20 000 is used as stationary phase.
Reinforced plastics based on unsaturated polyester resins — Determination of residual styrene monome...
The residual styrene monomer content in reinforced plastics based on unsaturated polyester (UP) resins is an important criterion in evaluating the degree of cure of UP resins in the polymerized state. The determination is carried out by extraction of the residual monomer styrene from the UP resin in the polymerized state using dichloromethane and subsequent gaschromatographic analysis of the…
Plastics — Homopolymer and copolymer resins of vinyl chloride — Determination of residual vinyl chlo...
Dissolution or suspension of a test portion in a suitable solvent, for example N,N-demethylacetamide, N,N-dimethylformamide, tetrahydrofurane or dichloroethane, free of any impurity with the same chromatographic retention time as vinyl chloride under the conditions of test. Determination of the vinyl chloride monomer content by gas chromatography using the "head space" sampling method…
Copper alloys — Determination of nickel content — Titrimetric method
The method is applicable to contents of nickel as an alloying element in all types of copper alloys listed in International Standards. ISO 4743 specifies principle, reagents, apparatus, procedure, expression of results and test report.
Guidelines for the presentation of International Standards dealing with the design of structures
The different approaches to the drafting of International Standards resulted in a lack of uniformity in the technical content, and in the layout and sequence of the subject matter, of such documents. This Technical Report has, therefore, been prepared to create guidelines for the presentation of International Standards dealing with the design of structures.
Copper and copper alloys — Determination of tin content — Spectrometric method
The method is applicable to the determination of tin contents between 0.005 and 0.5 % (m/m) in all types of copper and copper alloys listed in International Standards. A method applicable to the determination of tin contents below 0.005 % (m/m) is in preparation. ISO 4751 specifies principle, reagents, apparatus, procedure, preparation of calibration graph, expression of results and test report.
Copper and copper alloys — Determination of chromium content — Flame atomic absorption spectrometric...
The method is applicable to the determination of chromium contents between 0.003 and 2.0 % (m/m). ISO 4744 specifies principle, reagents, apparatus, sampling, procedure, expression of results and test report. An International Standard dealing with the sampling of copper and copper alloys is in preparation.
The method is applicable to products of cadmium-containing copper alloys listed in International Standards having cadmium contents between 0,0005 and 2,0 % (m/m). Specifies principle, reagents, apparatus, sampling, procedure, expression of results and test report.
Copper alloys — Determination of chromium content — Titrimetric method
The method is used for the determination of the total chromium content of copper-chromium alloys listed in International Standards. It is applicable to products having chromium contents between 0,10 and 2,0 % (m/m). Specifies principle, reagents, apparatus, procedure, expression of results and test report.
Copper and copper alloys — Determination of antimony content — Rhodamine B spectrometric method
The method is applicable to antimony contents between 0.001 and 0.1 % (m/m) in all types of copper and copper alloys listed in International Standards. The range of application may be extended by appropriate modification of the mass of the test portion, the extraction volume and the cell path length. Specific proposals to cover lower and higher concentrations are in preparation. ISO 5956…
