UL 1784 門組件的空氣泄漏試驗(yàn) – 適用范圍
本標(biāo)準(zhǔn)要求包括調(diào)查通過(guò)門組件和其他開(kāi)口式保護(hù)裝置（以下也稱為測(cè)試樣品）泄漏的空氣，這些保護(hù)裝置安裝在有意控制空氣泄漏的墻壁開(kāi)口中。
測(cè)試的目的是僅確定在閉合位置的測(cè)試樣品對(duì)整個(gè)開(kāi)口保護(hù)層表面施加規(guī)定的氣壓差所引起的漏氣的能力。
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.
