EN 1363-1 Fire resistance tests –Part 1: General RequirementsThe purpose of the method described in the European standard is to determine the behavior of a construction when subjected to a defined heat load and pressure.
The method provides the ability to quantify the capacity of an element, or a construction, to withstand high temperatures using functional requirements such as carrying capacity, density and thermal insulation to provide a few. The method provides the general requirements for fire resistance testing and is usually used in conjunction with other product-specific test standards. In this method, the default fire curve is defined.
Testing can be used for type approval and CE marking for designs where a product standard or a European Technical Approval Guideline (ETAg) is available.
Brief description of the method
The test itself takes place in a furnace which has an opening on which the test object is mounted. The furnaces at RISE Fire Research have a 3 x 3 m opening for testing vertical structures such as walls or fire doors and 5 x 3 opening for testing horizontal structures such as tile floors or ceilings. The furnace is then heated according to a defined time-temperature curve which represents a real fire where you get an overrun.
The method describes how the construction is to be mounted and how to position and mount the measuring equipment to be used.
The standard also sets out the requirements for accuracy of the measurements made and the instruments used. This may be, e.g. thermocouples, pressure sensors and deformation meters. The method also describes various types of connecting structures, as walls in which the test object, such as a fire door, must be mounted. Furthermore, the standard describes how to verify that the tested design complies with the drawing.
One common procedure is that the customer submits two test items, of which one is selected for testing and the other one is used for checking and verifying the design. Another important aspect described in the standard is how different designs should be conditioned before testing, ie how long they are to be stored in a certain climate. Finally, the standard contains instructions on what the test report should contain.
