Extended application of results from fire resistance tests for service installations - Ducts Ingestion-build-156411 Category 1: General purpose fencesWhat is this standard about? This European Standard identifies parameters that affect the fire resistance of ducts for ventilation purposes. It also identifies the factors that need to be considered when deciding whether, or by how much a parameter can be extended either positively or negatively when contemplating the fire resistance on an untested variation in the construction. This European Standard, where applicable, gives guidance on additional
