淮安市建筑構(gòu)件及材料*測試中心:
UL 263建筑構(gòu)件和材料-涵蓋范圍:
- These fire tests are applicable to assemblies of masonry units and to composite assemblies of structural materials for building, including bearing and other walls and partitions, columns, girders, beams, slabs and composite slab and beam assemblies for floors and roofs, they are also applicable to other assemblies and structural units that constitute permanent integral parts of a finished building.
- The classifications for building construction and materials are intended to register performance during the period of fire exposure and are not intended to be interpreted as having determined their acceptability for use after fire exposure.
- These requirements are intended to evaluate the length of time that the types of assemblies specified in1.1 will contain a fire or retain their structural integrity, or both, dependent upon the type of assembly involved, during a predetermined test exposure. the test evaluates the assembly's resistance to teat. and in some instances to a hose stream. while carrying an applied load, if the assembly is load bearing.
- Under these requirements a specimen is subjected to a standard fire exposure controlled to achieve specified temperatures throughout a specified time period. In some instances ,the fire exposure may be followed by the application of a specified standard fire hose stream. This exposure by itself may not be representative of all fire conditions; conditions may vary with changes in the amount, nature, and distribution of fire loading, ventilation, compartment size and configuration, and heat sink characteristics of the compartment. These requirements provide a relative measure of fire performance of comparable assemblies under these specified fire exposure conditions. Any variation from the construction or conditions that are tested such as size. method of assembly, and materials ,may substantially change the performance characteristics of the assembly.
UL 263建筑構(gòu)件和材料-標(biāo)準(zhǔn)概述:

CAN/ULC-S127建筑材料和構(gòu)件的*測試-標(biāo)準(zhǔn)名稱:
CAN/ULC-S127:standard corner wall method of test for flammability characteristics of Non-melting foam plastic building materials.
CAN/ULC-S127:墻角法測定非融化泡沫塑料建筑材料的可燃性特性
CAN/ULC-S127建筑材料和構(gòu)件的*測試-標(biāo)準(zhǔn)范圍:
該可燃性測試方法適用于暴露于火源中不熔化的某些小密度絕緣材料(參考附錄A)。它是根據(jù)火焰蔓延分類來評估泡沫塑料的可燃性,在建筑材料或構(gòu)件的表面燃燒特性的測試方法,需要使用計算公式FSV = 92.5 d/t,公式中”d”& “t”為必要參數(shù).
本測試的目的是將材料安裝在*測試用的墻角配置中暴露于火源,確定材料的燃燒特性。
