This new door and window testing equipment complies with the standard GB/T7106-2019(Testing Methods for Air Tightness, Water Tightness and Wind Pressure Resistance of Building Exterior Doors and Windows) [Testing Items] and is used for the testing of the three physical properties of doors and Windows, namely air tightness, water tightness and wind pressure resistance.
【 Applicable Standard 】GB/T7106 "Testing Methods for Air Tightness, Water Tightness and Wind Pressure Resistance of Building Exterior Doors and Windows"
【 Product Features 】 The physical performance testing equipment for doors and Windows is the second-generation new type of three-property testing equipment for doors and Windows developed by our company based on the new standard draft for review. It features simple specimen clamping and full automatic control of the test.
The new national standard GB/T 7106-2019 door and window three-property testing equipment is used to test the air tightness, water tightness and wind pressure resistance of building exterior doors and Windows, and quantitatively test performance parameters.
The equipment's testing functions simultaneously meet the testing requirements of the current test standard (GB/T 7106-2008) and the new national standard (GB/T 7106-2019, implemented on November 1, 2020).

The meaning of variable volume box lock:
1. Improve the flow response rate.
2. Improve the accuracy of flow sampling.
3. Make low-pressure gradient flow testing possible.

Advantages of variable lock box technology
1. Effectively reduce the length of the sealing contact gap between the box buckle and the static pressure box, increase the box buckle's ability to collect seepage, and reduce the probability of box buckle leakage.
2. Ensure the consistency of the contact area between the static pressure box part of the specimen and the contact area around the box to the greatest extent possible, and avoid additional seepage caused by the sealing of non-specimen parts.
3. The brand-new clamping method highly simulates the construction and installation method of the test piece under actual working conditions, without causing stress-type deformation.
4. Fully modular sealed partition, suitable for most practical application specimens in the market.
