C Tables showing examples of basic stresses as a
    function of the operating temperature TS, the time to
    failure t and the chemical resistance factor fCR
D Examples of basic stress curves with water for
    polyethylene pipes with a nominal stress sN = 8 MPa
E Examples of basic stress curves with water for
    polybutene pipes with a nominal stress sN = 8 MPa
