GB/T 4132 insulation materials and related terms

3 Terms and definitions

The following terms and definitions as defined in GB/T 4132 apply to this document.

4 Principle

The method adopts a large-sized sample consistent with the external wall insulation engineering construction practice, uses special equipment to generate negative pressure, and external wall insulation Wind suction is applied to the surface of the system to test the wind pressure at the time of sample failure by a specified number of loading cycles.

5 Test equipment

Negative pressure tank. capable of generating a negative pressure that meets the test requirements. The opening size should be larger than the sample size. Should have sufficient depth to ensure that the exterior wall The external insulation system sample may be deformed within a range that allows the pressure applied to the external insulation system to be kept constant. The negative pressure box is installed around The specimen of the external thermal insulation system was tested on the frame.
