Test methods of air permeability, watertightness, wind load resistance performance for building external windows and doors 1 Scope This standard specifies the terms and definitions, test principle, test device and test preparation of air permeability, watertightness and wind load resistance performance of building external windows and doors, air permeability performance test, watertightness test, wind load resistance performance test, repeated air permeability performance test, repeated watertightness performance test and test reports. This standard is applicable to the laboratory test of air permeability, watertightness and wind load resistance performance of building external windows and doors. The test objects are only restricted to windows and doors or windows and doors with attached frames, and do not involve the joint parts between the windows and doors and other structures such as building walls. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. GB/T 5823 Terminology for building windows and doors GB/T 31433 General specification for building curtain walls, windows and doors GB 50009 Load code for the design of building structures GB 50178 Standard of climatic regionalization for architecture 3 Terms and definitions For the purposes of this document, the terms and definitions given in GB/T 5823 and the following apply. 3.1 external windows and doors the general term of external windows and doors of buildings 3.2 pressure difference the difference between the absolute air pressures on the interior and external surfaces of the external windows and doors Note: When the pressure on the outdoor surface is higher than that on the indoor surface, the pressure difference is positive; on the contrary, it is negative. 3.3 air permeability performance the ability of external windows and doors to prevent air permeability when the openable part is normally locked 3.3.1 standard condition test conditions with an air temperature of 293K (20℃), an atmospheric pressure of 101.3 kPa (760 mmHg), and an air density of 1.202 kg/m3 3.3.2 volume of air leakage the volume of air passing through the test body per unit time 3.3.3 volume of extraneous air leakage the volume of air leakage other than the volume of air leakage of external windows and doors themselves in the measuring area of the collective box 3.3.4 total volume of air leakage the sum of the volume of air leakage through the external windows and doors themselves and the volume of extraneous air leakage 3.3.5 collective box fastened box a box body connected with the opening of the pressure box and used for collecting and measuring the volume of air leakage and volume of extraneous air leakage permeating into or leaking out of the external windows and doors 3.3.6 openable joint length the sum of the lengths of the interior joints of the openable parts on external windows and doors Note: The measured value of indoor surface shall prevail. 3.3.7 volume of air flow through the unit joint length of the opening part
