NFPA 251建筑結(jié)構(gòu)和材料耐火測試-簡介
NFPA251本標(biāo)準(zhǔn)提供了建筑構(gòu)件和構(gòu)件耐火性能的防火測試方法。本標(biāo)準(zhǔn)描述了評(píng)估組件類型包含火災(zāi)、保持其結(jié)構(gòu)完整性或展示兩種適當(dāng)連接的持續(xù)時(shí)間的方法。
This standard provides methods of fire tests for the fire-resistive properties of building members and assemblies, This standard describes methods to evaluate the dura tion for which the types of assemblies noted in 1.3.1 contain a fire, retain their structural integrity, or exhibit both proper ties, depending on the type of assembly involved during a pre-
determined test exposure.It is the intention of this standard that fire resistance ratings be based on performance during the period of expo sure and not be used to determine suitability for use after fire exposure The results of these tests are one factor in assessing fire performance of building construction and assemblies.
