    Describes the procedure and the precautions to be taken in drawing representative samples of the substances for the purpose of their analyses. It also sets out, in Annex A, a diagrammatic representation of a system for the disposal of the portion of the sample not used in the analysis, and, in Annex B, the sequence of operations for filling a sample cylinder.

  • ISO 3696-1987 - 中外标准 - - 1987/4 - 现行
    Specifies the requirements for three grades for the analysis of inorganic chemicals. Not applicable to organic trace analysis, analysis of surface-active agents and biological or medical analysis. The material shall be a clear, colourless liquid as assessed by inspection. Classifies according to the content: free from dissolved or colloidal ionic and organic contaminants, very low inorganic, organic or colloidal contaminants and suitable for laboratory wet chemistry work. Specifies the pH and conductivity measurement, the limit tests for oxidizable matter and for reactive silica, the measurement of absorbance and the determination of residue after evaporation at 110 °C.

    Care should be taken that any test portion is representative of the sample with respect to the property or constituent to be determined. In case of compositions of the original mix any surface bloom should be incorporated, but for final bulk bloom should be removed. If test pieces are taken from manufacturer''s products, vulcanized rubber has to be separated from other possible components which should be done by mechanical means to avoid heat generation.
