适用范围：This part of ISO 834 specifies test procedures for determining the fire resistance of non-loadbearing ceiling elements which possess fire resistance independent of any building element above them, when exposed to heating from below the ceiling. It is applicable to self-supporting ceilings and to ceilings suspended from, or fixed directly to, a supporting construction.The application of this test to other untested forms of construction is acceptable when the construction complies with the direct field of application as given in this part of ISO 834 or when subjected to an extended application analysis in accordance with ISO/TR 12470t1l Since ISO/TR 12470 gives only general guidelines, specific extended application analyses are to be performed only by persons expert in fire-resistant constructions.This part of ISO 834 is not applicable to ceilings used as a horizontal fire barrier for the protection of a loadbearing element above, in which case performance is assessed as an integral part of the complete assembly using ISO 834-5.
