Recently, the plastic window and door profile of China's full implementation of new standards. At present, China has become the world's largest plastic doors and windows of the producing and consuming countries. But a long time, plastic doors and windows in the production and marketing process, the industry has been in use are the 1990s developed GB/T8814-1998 standards. According to China's level of production of plastic doors and windows of the actual situation, are not suited to this standard has now rapid development of plastic doors and windows industry situation. To this end, the National Standardization Technical Committee of plastic products branch of this standard was revised again, and obtained the relevant state departments audited.
     New standards compared with the old standard, the standard international practice and a substantial increase. The main difference is: First, raise the profile of the bending modulus of elasticity, from the original standards in 1960 to the 2200 standards; Second, the use of the different climate, a classification profile. One of the H-profile impact of the drop hammer in quality and drop hammer hammerhead radius remain unchanged, will drop hammer from the original height of 1 meter has been raised to 1.5 meters. This means that the drop hammer impact strength will increase by 50 percent, so that a specific profile in the regional climate of brittle fracture failure of endurance greatly enhanced, so that the safety of plastic doors and windows can be greatly increased; Thirdly, the plastic profiles of anti-aging Extension of the time. This is undoubtedly the quality of plastic profiles require a revolutionary change. Product standards, once achieved, will greatly extend the life of plastic doors and windows
