4.5 Static Load

  4.5.1 The following levels of loading should be applied uniformly, as far as practicable, along the top edge of the vertical specimen or surface of the horizontal specimen:

- bulkheads: 7.0 kN/m of the width,
- decks: 3.5 kN/m2 of the area.

 The load may be applied hydraulically, mechanically or by the use of weights.

  4.5.2 The loading equipment should be able to simulate the conditions of loading, as appropriate, for the test construction. The loading equipment should also be capable of maintaining the test load at a constant value (to within ± 5% of the required value) without changing its distribution for the duration of the load-bearing capacity period; it should not significantly influence the heat transfer through the specimen nor impede the use of the thermocouple insulating pads; it should not interfere with the measurement of surface temperature and/or deformation and should permit general observation of the unexposed face.

  4.5.3 The total area of the contact points between the loading equipment and the test specimen surface should not exceed 10% of the total area of the surface of a horizontal test specimen. The equipment should be capable of following the maximum deformation and the rate of deformation of the test specimen.

  4.5.4 The test load should be applied at least 15 min before the commencement of the heating period.
