[0002] There is no clear term definition of "fire-resistant window" in China's standard system. It is a common name for building exterior windows with fire integrity in the current window industry. The so-called "fire-resistant window" is a new product that has been gradually put into use with the implementation of the "Code for Fire Protection Design of Buildings" (GB50016-2014); according to the requirements of this code, windows with fire integrity need to be tested in accordance with the provisions of the "Test Method for Fire Resistance of Glazed Elements" (GB / T12513-2006) and meet the requirements of corresponding fire integrity of 0.5h or 1.0h; however, whether such windows must have an automatic closing function is not clearly defined in the code, which also leads to ambiguity; in specific practices, for such windows, that is, non-insulated glazed elements (with movable sashes), the fire inspection department requires that movable window sashes be installed with window sash opening and closing control devices and be tested in accordance with the "Test Method for Fire Resistance of Glazed Elements" (GB / T12513-2006) and the "Fire Windows" (GB16809-2008).
