Fire resistance tests according to European standards result in a Field of Direct Application (DIAP). This Field of Direct Application offers some variations on the tested construction. In addition to the DiAp, it is also possible to extend the Field of Application of the test results for many construction products based on European ExAp (Extended Application) standards. There are more possibilities, such as being allowed to build a construction higher than tested or to provide for instance a door with different hinges or different glass.

There are more possibilities, such as being allowed to build a construction higher than tested or to provide for instance a door with different hinges or different glass.
In doing so, Efectis offers a smart solution. By expanding the Field of Application, more possibilities are created based on fewer tests.
The outcome of an ExAp report can also be included in a classification. For products where CE marking is mandatory, the extended Field of Application is also used as input for the Declaration of Performance (DoP).
Efectis can issue Extended Application reports for test results based on the following standards: EN 1364-1, EN 1364-2, EN 1364-3, EN 1365-1, EN 1366-2, EN 1366-3, EN 1366-4 EN 1634-1 and EN 1634-3.

Fire testing (Resistance to Fire, Cladding) provides a direct field of application (DIAP) for the product or system assessed. However, testing each and every possible product variant would impose an unbearable cost and time outlay for manufacturers and assessors. Therefore, a set of standards has been issued to set the procedures for extending the field of application (EXAP) of construction products, or by assessment in lieu of fire testing where there is no specific standard for extended application; also called ‘desktop study’. However, the extension is not automatically guaranteed, but depends on the results of the analysis conducted on the test data made available by the sponsor/manufacturer. It is therefore compulsory to demonstrate data of at least one fire test.
Based on EXAP rules, greater variations are allowed in contrast to the DIAP rules which are limited to the particular product or design as tested. As a result, the EXAP rules practically allow manufacturers to reduce the total number of tests required. An additional advantage of the EXAP standards is the possibility of having the output classified and used as a Declaration of Performance (DoP).
Efectis actively participate in technical committees, collaborating in working groups with various industrial and academic partners for development or revision of both DIAP and EXAP standards.
Below standards and guidelines have been developed to facilitate above-mentioned services:
Efectis team of experts can provide extended field of application (EXAP) reports for extending the application of existing fire test data, based on
In the cases where there is no specific standard for the extended application, if possible, our experts can produce assessment reports in accordance with the principles in BS EN 15725 as required by Approved Document B Amendment 2020 Appendix B.
It is therefore advised that manufacturers to get in touch with our engaged and highly skilled personnel to discuss options for testing and possible future use of data for offering a tailored to the needs solution.
