BS EN 15254-5 defines rules for extended applications, provides guidance, and, where appropriate, defines procedures, for variations of certain parameters and factors associated with the design of internal and external non-loadbearing walls constructed of metal sandwich panels and that have been tested in accordance with EN 1364-1, which could generate a classification in accordance with EN 13501-2.
EN 15254-5 applies for self-supporting, double skin metal-faced sandwich panels having an insulating core bonded to both facings as defined in EN 14509.
BS EN 15254-5 on the extended application of results from fire resistance tests for non-loadbearing walls is useful for:
Extended application is a prediction of the expected fire resistance of fire-resistant metal faced sandwich panels. It may be based on interpolation between or extrapolation from test data.
BS EN 15254-5 provides you with rules, testing procedures, guidance and calculation methods for extended application of results from fire resistance tests for non-loadbearing walls of metal sandwich panel construction. The fire-resistant metal-faced sandwich panels after extension will achieve the required fire performance to be tested according to EN 1364-1.
This will help you to extend the span length for test results according to EN 1364-1.
BS EN 15254-5:2018 supersedes BS EN 15254-5:2009, which is withdrawn.
