Mechanical performance requirements for plastic windows
Not more than 50N
Under the action of 500N force, the residual deformation The shape should not be greater than 3mm, the specimen should not be damaged, and the use function can be maintained. Under the action of 300N force, residual deformation that does not affect the use is allowed, and the specimen is not allowed to break, and the use function can be maintained.
Under the action of 200N force, the specimen is not allowed to be damaged, and residual deformation that affects the use function is not allowed. The switching speed is 10-20 times/min. After not less than 10,000 switches, the specimen and hardware should not be damaged, and its fixings and glass moldings should not loosen. www.bzxz.net
The switching speed is 15m/min, and the switching should not be less than 10,000 times. The specimen and hardware should not be damaged. After 10 consecutive switches simulating a wind force of level 7, the specimen is not damaged and the original switching function is maintained. It can support a force of 200N, and displacement is not allowed. The profile at the connection should not break. 10N10 times, the specimen should not be damaged.
The average value is not less than 3000N, and the minimum value is not less than 70% of the average value. The weather resistance test methods are divided into the following three categories: artificial aging test, natural weather resistance test and whole plastic window weather resistance test. In general, artificial accelerated aging or natural weathering test is sufficient. When it is necessary to test the weathering resistance under specific use conditions, the whole window test is performed. 3.3.1 Artificial accelerated aging
Artificial aging of profiles for external windows should be no less than 1000h; artificial aging of profiles for internal windows should be no less than 500h; the appearance, discoloration and impact strength after aging should meet the requirements of Table 3. Table 3 Requirements for appearance, discoloration and impact strength of profiles after aging Item
Discoloration
Impact strength retention rate
Natural aging performance
No bubbles, cracks, etc.
Should not exceed 3 levels of gray
Simply supported beam impact strength retention rate is not less than 70% Test method According to GB3681, its performance should meet the requirements of Table 3 after two years of exposure. 3 Natural weathering resistance of whole windows under actual use conditions 3.3.3
After the window is used in a building for two years, its performance should meet the requirements of Table 3. 4
