GB/T 9978.2-2019 Fire Resistance Tests—Elements of building construction—Part 2:Guidance on measuring uniformity of furnace exposure on test samples
Abstract
This part of GB/T 9978 specifies a test method for measuring the uniformity of the fire exposure of specimens during fire resistance tests in a fire resistance test furnace in accordance with the provisions of GB/T 9978.1. This part provides the types and placement locations of measurement instruments for parameters such as the temperature, air velocity, and oxygen content near the surface of the simulated specimens. The interior of the simulated specimens is a cold-bent steel frame, and the fire-exposed surface of the specimens is made of gypsum board.
This part does not include performance requirements for fire resistance test furnaces.
