Brief introduction

New standard for physical performance and three property testing of doors and windowsdeviceMeets the requirements of the national standard GB/T7106-2019 "Test Methods for Air tightness, Water tightness, and Wind Load Resistance of Building External Doors and Windows", and is suitable for testing the air tightness, water tightness, and wind load resistance of building doors and windows.The three properties testing machine for doors and windows is mainly used to test the wind pressure resistance, air permeability and rain water permeability of external windows made of various materials, french window with external door function, external doors of buildings, curtain walls, etc. It is particularly suitable for testing the water tightness, air tightness, and wind pressure resistance performance of doors, windows, curtain walls, production enterprises, construction engineering quality inspection centers, product quality supervision and inspection institutes, and building science research institutes.
