The following documents are essential to the application of this document. For the dated
documents, only the versions with the dates indicated are applicable to this document;
for the undated documents, only the latest version (including all the amendments) is
applicable to this standard.

3 Terms and definitions
The terms and definitions, which are defined in GB/T 34327, as well as the following
terms and definitions, apply to this document.
3.1
Standard condition
The test conditions where the air temperature is 293 K (20 °C), the atmospheric
pressure is 101.3 kPa (760 mm Hg), the air density is 1.202 kg/m3.
3.2
Pressure difference
The absolute air pressure difference -- between the indoor and outdoor surfaces of
the specimen.
Note. When the surface pressure on the outdoor is higher than the surface pressure on the
indoor, the pressure difference is positive; otherwise, it is negative.
3.3
Air permeability performance
The ability of the specimen to prevent air leakage, when the openable part is closed.
3.4
Watertightness performance
When the openable part is in a closed state, the specimen's ability to prevent
rainwater from leaking indoor, under the simultaneous action of wind and rain.
3.5
Wind load resistance performance
When the openable part is in a closed state, under the action of wind pressure, the
deformation of the main stress-bearing components of the specimen does not exceed
the allowable value and no structural damage or functional impairment occurs.
3.6
Grade testing
Testing, which is carried out to determine the performance level of the specimen.
3.7
Engineering testing
Testing, which is conducted to determine whether the specimen meets the
performance requirements of the engineering design.
4 General requirements
4.1 The grading and index values of air permeability, watertightness, wind pressure
resistance performance of building curtain walls shall comply with the requirements of
GB/T 31433.
4.2 The testing shall be carried out, under the condition that the ambient temperature is
not lower than 5 °C.
4.3 The order of grade testing should be carried out, in the order of air permeability and
wind pressure deformation resistance p1, watertightness and wind pressure resistance
repeated pressurization p2, design wind load standard value of wind pressure resistance
product p3, design wind load value of wind pressure resistance product pmax.
4.5 The air permeability performance of a double-layer curtain wall is graded, based on
its overall air permeability performance index. The watertightness performance of a
double-layer curtain wall is graded, based on the watertightness performance index of
the first layer of curtain wall, which has watertight requirements. For the wind pressure
resistance of a double-layer curtain wall, the inner layer and outer layer are tested and
graded, respectively.
4.6 Watertight performance testing is divided into stable pressurization method and
fluctuating pressurization method. For engineering testing in tropical storm and
typhoon areas, the fluctuating pressure method shall be used.
4.7 Necessary safety protection measures shall be taken during testing.
Note. Safety protection includes protection of personnel and protection of instruments and
equipment.
5 Testing principle
Install the full-scale specimen on the pressure box. Use the pressure supply device to
form a stable pressure difference or a pressure difference that fluctuates according to a
certain period, on both sides of the specimen, to simulate the state of the specimen when
it is subjected to different wind loads.

qfg
8.4.3 Determination of total volume of air leakage qz
Testing after removing the sealing measures added to the specimen. The testing
procedure is the same as 8.4.1.2.
8.5 Processing of testing data
8.5.1 Processing of grade testing data
8.5.1.4 Under the action of 100 Pa pressure difference, the volume of air leakage qA'
per unit area is calculated, according to formula (6).
8.5.2 Processing of engineering testing data
8.5.2.1 Calculate the overall air leakage volume (including the openable part) qs and the
air leakage volume of the openable part of the specimen qk, under the standard state and
