In line with international standards in China to implement standards for plastic doors and windows profiles

China's new standards for plastic door and window profiles are fully implemented. At present, China has become the world's largest producer and consumer of plastic doors and windows. But for a long time, in the production and sales process of plastic doors and windows, the industry has been using the GB/T8814-1998 standard developed in the 1990s. According to the actual situation of China's plastic doors and windows production level, this standard has not been adapted to the rapid development of the plastic door and window industry. To this end, the Plastics Branch of the National Product Standardization Technical Committee re-revised this standard and obtained approval from the relevant state agencies.

Compared with the old standard, the new standard has greatly improved with the international standards. The main differences are: First, the bending elastic modulus of the profile is increased, from the original 1960 standard volume to the 2200 standard volume; Second, the profile is graded according to the climate in the area of ​​use. Wherein, the drop hammer impact on the H-profile was improved from the original 1 meter to 1.5 meters under the condition that the weight of the dropping hammer and the radius of the hammer head were constant. This means that the drop impact strength is increased by 50%, so that the resistance of the profile to the embrittlement fault in the specific climatic region is greatly enhanced, the safety of the plastic door and window is greatly improved, and thirdly, the aging time of the plastic profile is prolonged. Now. This is undoubtedly a revolutionary change in the quality requirements of plastic profiles. Once the product standard is reached, the service life of plastic doors and windows will be greatly extended.
