Standard Practice for Determining the Steady State Thermal Transmittance of Steel Door and Frame Assemblies
测定钢制门和框架组件稳态热传导率的标准实施规程
本规程的目的是建立标准试样尺寸、试验条件和评级系统,以确定可操作钢制门和框架组件的热传导率。
The purpose of this practice is to establish a standard test specimen size, test conditions and a rating system for determining the thermal transmittance of operable steel door and frame assemblies.
