3.4 Data to be submitted

  3.4.1 In order for the analysis to be carried out, the following information should be submitted:

  • .1 detailed drawings of the door, the door frame and the closure and locking devices including the indications of clearances and interferences;

  • .2 test report of the prototype used to extrapolate the results.

  • In this respect, additional instrumentation should consist of two sets of three 1.6 mm diameter thermocouples fitted through the thickness of the leaf, at depths of 1/3 t, 1/2 t, 2/3 t. Such sets should be fitted, on the upper part of the door, within a circle of 100 mm in diameter whose centre is 150 mm aside of the surface thermocouples fitted in the centre of the top quarters;

  • .3 mechanical characteristics of all materials used for the construction of the door and its insulation:

    • .3.1 Young’s module;

    • .3.2 yield strength; and

    • .3.3 density; and

  • .4 thermal properties:

    • .4.1 thermal expansion coefficient;

    • .4.2 thermal conductivity; and

    • .4.3 specific heat.

  3.4.2 Since all these properties are temperature dependent, it is necessary that the required data be given as a function of the temperature range foreseen for the fire tests. Where it is not possible to obtain experimental data, an engineering evaluation should be submitted with the supporting considerations for the proposed curves of variation of mechanical and thermal characteristics as a function of the temperature in the considered range.
