The standard of this new door and window testing equipment GB/T7106-2019 (Detection method for airtightness, watertightness and wind pressure resistance of external doors and windows of buildings) [test item] is used for the detection of the physical three properties of doors and windows, namely air tightness, water tightness and wind pressure resistance.

【Applicable Standard】GB/T7106 "Testing Methods for Airtight, Watertight and Wind Pressure Resistance of Exterior Doors and Windows of Buildings"

【Product features】The physical performance testing equipment for doors and windows is the second generation of new doors and windows three performance testing equipment developed by our company according to the new standard draft for review, which has the characteristics of simple clamping of specimens and automatic control of the test.

The new national standard GB/T 7106-2019 three performance testing equipment for doors and Windows is used to detect the airtight performance, watertight performance and wind pressure resistance of building doors and Windows, and quantify the performance parameters.

The test function of the equipment meets the test requirements of the current test standard (GB/T 7106-2008) and the new national standard (GB/T 7106-2019, implementation date November 1, 2020) at the same time.

Variable volume buckle box significance:

1. Improve the traffic response rate.

2. Improve the accuracy of flow sampling.

3. It makes it possible to test the flow rate of low pressure gradient.

Advantages of variable buckle box technology:

1. Effectively reduce the length of the sealing contact gap between the buckle box and the static pressure box, increase the ability of the buckle box to collect permeability, and reduce the leakage probability of the buckle box.

2. The maximum degree ensures the consistency between the contact area of the static pressure box of the specimen and the contact area around the buckle box, and avoids the additional permeability caused by the partial sealing of the non-specimen.

3. The new clamping method highly simulates the construction and installation method of the specimen under actual working conditions, and does not produce stress-type deformation.

4. Full modulus sealed partition, suitable for most market practical application specimens.

2. According to (meet) the standard

GB/T 7106-2008 "Classification and Testing Methods for Airtight, Watertight, Wind Pressure Resistance of External Doors and Windows of Buildings".

GB/T 7106-2019 "Testing Methods for Airtight, Watertight and Wind Pressure Resistance of External Doors and Windows of Buildings" will be implemented on November 1, 2020

GB/T3143-2015
