  • ISO 7231-1984 - 中外标准 - - 1984/12 - 作废
    The air flow value may be used to give an indication of the effects of formulation and production variables on the cellular structure. Describes the method with an apparatus either for negative or for positive pressure. Two figures show the test arrangement.
  • ISO 6943-1984 - 中外标准 - - 1984/12 - 作废
    Describes a method relating to fatigue under repeated deformations. Believed to be suitable for reasonably stable stress-strain properties. Materials to be tested must meet special criteria, otherwise experiment and interpretation may be difficult. Distinction should be made between this test and the flexometer tests of ISO 4666/1 to 3. Caution when relating standard test results to service performance. Annex with explanatory notes. One table and two figures.
  • ISO 7142-1984 - 中外标准 - - 1984/12 - 作废
    The test methods to be applied to an individual epoxy resin shall be agreed between the interested parties. IS also applicable to solutions made from epoxy resins; the methods described are not intended for epoxy esters. The determination of the hydroxyl value of these resins is given in the annex.
  • ISO 2577-1984 - 中外标准 - - 1984/12 - 作废
    Specification of a method of determining the moulding shrinkage and the post-shrinkage of moulded test specimens of thermossetting materials. Moulding is carried out under the conditions specified in ISO 295 or according to the relevant material specification. The mould shrinkage is given as a percentage of the corresponding dimensions of the mould. Post-shrinkage shall be determined after a specified heat of the test specimen. The change in length is reported as a percentage of the original length.
  • ISO 7279-1984 - 中外标准 - - 1984/11 - 废止
    Specification of socket inside diameters for insertion. Specification of two kinds of sockets (A and B) with different conicity corresponding two different methods of jointing.
  • ISO 7245-1984 - 中外标准 - - 1984/11 - 现行
    Specifies ABS-plastics for pipe applications, the properties chosen to designate ABS plastics for pipes are: acrylonitrile content, Vicat softening temperature, melt flow rate, impact strength and flexural modulus. Reference is made to ISO 2580.
