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.
