UL 1784 门组件的空气泄漏试验 – 适用范围
本标准要求包括调查通过门组件和其他开口式保护装置（以下也称为测试样品）泄漏的空气，这些保护装置安装在有意控制空气泄漏的墙壁开口中。
测试的目的是仅确定在闭合位置的测试样品对整个开口保护层表面施加规定的气压差所引起的漏气的能力。
These requirements cover the investigation of air leakage through door assemblies and other opening protectives (hereafter also referred to as test sample) installed in wall openings where air leakage is intended to be controlled.
The purpose of the test is to determine only the resistance of a test sample, in the closed position, to air leakage resulting from a specified air pressure difference applied across the surface of the entire opening protective.
