  • ISO 181-1981 - 中外标准 - - 1981/12 - 废止
    Specification of a method for determination of the relative flammability characteristics of small specimens of rigid plastics. Assessment of the flammability after bringing its free end into contact with a silicon carbide rod electrically heated to 955 °C, for a specified period of time. The result is expressed as the average burning time and the average destroyed length.
  • ISO 4590-1981 - 中外标准 - - 1981/12 - 作废
    Specifies a general method ba measurement first of geometrical volume and of the air impenetrable volume of test specimens. This method provides for correcting the apparent open cell volume by taking into account the surface cell opened by cutting during specimen preparation. Two alternative methods and corresponding apparatus are specified for the measurement of the impenetrable volume. The results are to be used for comparison purposes only.
  • ISO 1922-1981 - 中外标准 - - 1981/11 - 作废
    The method is based on the application of a shear stress to a test specimen of defined shape by means of metal supports bonded to the specimen. The adhesive used to fix the metal supports to the test specimen shall be such that shear strength and modulus of the adhesive film are significantly greater than that of the cellular material under test.
  • ISO 3915-1981 - 中外标准 - - 1981/11 - 现行
    Specifies the requirements for the laboratory testing of the resistivity of specially prepared specimens of plastics made conductive by the incorporation of carbon black. The test is suitable for materials having a resistivity of less than 104 Ohm x m. A stable d.c. current is passed between electrodes at the ends of a test piece. A schematic diagram of the test circuit is given. The voltage drop between the two potential electrodes, set on the test piece while the current flows, is measured with an electrometer. The resistance of the portion of the test piece between the potential electrodes is independent of contact resistances.

    Specification of the characteristics and the choice of the measuring equipment and procedure for determination of the linear dimensions of sheets, blocks or test specimens of ceelular material (flexible and rigid). Depending on the range of the dimensions to be measured different measuring instruments are recommended.
