NFPA 252  Standard Methods of Fire Tests of Door Assemblies

NFPA 252  門組件的防火試驗用標準方法

 

本標準規定了適用于防火門總成的標準化消防和軟管流試驗程序，旨在通過防火墻中的門孔阻止火災蔓延。本標準的目的是規定特定的火災以及防火門組件的軟管流試驗程序，以標準化確定此類組件在阻止火災（火焰、熱量、溫度、溫度、溫度和溫度）蔓延方面提供的防火等級的方法。

 

This standard prescribes standardized fire and hose stream test procedures that apply to fire door assemblies intended to be used to retard the spread of fire through door openings in fire-resistive walls ，The purpose of this standard is to prescribe specific fire

and hose stream test procedures for fire door assemblies in order to standardize a method for determining the degree of fire protection provided by such assemblies in retarding the spread of fire (flame, heat, and hot gases) through door open- ings in fire-resistive walls The degree of fire protection measured in units of time is not an absolute value because all possible actual fire scenar ios are not represented by the standard fire exposure described herein This standard allows different fire door assemblies to be pared with each other in order to evaluate their relative performance as measured against a standard fire exposure.
