Foreword
This standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces GB/T 15227-2007 "Test methods for airtight, watertight and wind pressure resistance of building curtain walls", and GB/T 15227-
Compared with.2007, the main technical changes are as follows.
--- Adjust the standard structure, add general requirements, detection principles and detection devices (see Chapter 4, Chapter 5, Chapter 6);
--- Increase the testing requirements for open curtain walls (see 4.4);
--- Increase the detection requirements for double-layer curtain walls (see 4.5, 7.8);
--- Increasing the detection method for additional air permeability when testing for airtightness (see 8.4.1);
--- Engineering detection methods to increase airtight performance (see 8.2);
--- Increase the air-tightness performance test air flow measurement system calibration method (see Appendix A);
--- Increase the watertight performance detection method of the sprinkler system (see Appendix B);
--- Adjust the safety test method for wind pressure resistance test (see 10.2.1.5 and 10.2.2.5, 4.3.4.6 of the.2007 version);
--- Adjust the safety test assessment of wind pressure resistance test (see 10.3.2.1.3, 10.3.2.2.3 and 10.3.2.2.4,.2007 version
4.3.5.2.3).
This standard was proposed by the Ministry of Housing and Urban-Rural Development of the People's Republic of China.
This standard is under the jurisdiction of the National Technical Committee for Standardization of Curtain Wall Doors and Windows (SAC/TC448).

3 terms and definitions
The terms and definitions defined in GB/T 34327 and the following apply to this document.
3.1
Standard condition
Test with air temperature of 293K (20 ° C), atmospheric pressure of 101.3kPa (760mmHg), and air density of 1.202kg/m3
condition.
3.2
Pressuredifference
The absolute air pressure difference between the indoor and outdoor surfaces of the test piece.
Note. When the pressure on the outdoor surface is higher than the pressure on the indoor surface, the pressure difference is positive; otherwise it is negative.
3.3
