1 Scope

This standard specifies the dew point of insulating glass for building windows and doors, curtain walls, gas barrier layer thickness, inert gas content, wave curvature, Surface stress field detection methods. This standard applies to the construction of windows and doors, curtain wall with insulating glass on-site testing. Among them, the surface stress on-site testing methods applicable to the float Tempered glass made of glass, the test surface is float glass immersion tin surface; inert gas content of the field detection methods for inflatable hollow glass.

3 Terms and definitions

The following terms and definitions apply to this document. 3.1 Inert gas content In a fixed gas chamber, the inert gas volume ratio. Note. The inert gas content of the current stage content, non-initial content.

4 dew point

4.1 detection principle The low temperature characteristics of the dry ice will be used to cool the cold end of the adjustable temperature dew point meter. By controlling the distance between the dry ice and the cold end, the temperature of the cold end will be continuous Controllable. On-site inspection, the cold end of the hollow glass surface with full contact, the cold end of the hollow glass surface to cool the local cooling. When gradually reduced Cold-side temperature reaches the specified temperature and contact with the surface of the insulating glass to achieve the specified time, observe the hollow glass cavity is connected Touch parts condensation or frosting. 4.2 detection equipment 4.2.1 Adjustable temperature dew point meter or other testing instruments that meet the requirements. Detection equipment temperature measurement range of -60 ℃ ~ 0 ℃, accuracy is ± 1 ℃. 4.2.2 Adjustable temperature dew point meter. The cold end, the temperature guide block, the barrel, the outer barrel, adjusting ring, spring, dial indicator and other components, the structure of the instrument shown in Figure 1 Show. The diameter of the cold side contact with the glass should be 25 mm.
