Or how many square tests to achieve
Aluminum alloy window testing requirements are generally three test, detection of disturbed square calculation, is the specification requirements, this year began to aluminum alloy window detection has a clear provision, the general testing agencies can only do plant aluminum alloy window detection, 09 years Six months require energy-saving aluminum alloy windows and plastic windows to the national testing unit to detect. Online can be found. Send the window to the minimum standard size specifications in the 1500 cm X1500 cm third gear, the detection of watertight performance, gas and water performance, engage in wind pressure performance (energy-saving type to do the performance of four). Do not generally detect the door. I do not know if you can understand.
