This standard applies to methods that use a blower to create a pressure difference between the inside and outside of a building to test the airtightness of buildings and parts of buildings that are mainly used for residential purposes. Notes 1. A house in this standard refers to a single dwelling unit such as a detached house, an apartment complex, or a tenement house. This standard can also be applied to general buildings. 2. Methods for creating a pressure difference between the inside and outside of a building include pressurizing or reducing the pressure inside a building, and these methods are called the pressurization method and the depressurization method, respectively.
