    Abstract - (Show below) - (Hide below)

    IEC 60763-2:2007 gives methods of test applicable for the material classified in IEC 60763-1. This edition includes the following significant technical changes with respect to the previous edition:
    The standard has generally been revised editorially and brought into line with IEC 60641-2;
    The test method for the determination of the internal ply strength has been replaced with an alternative method; and
    The test method for the determination of the thermal resistance has been enlarged in its scope.
