Security doors implement new national standards Since the 1st of this month, the National Standards Commission issued a new national standard for anti-theft security doors. The standard will divide the anti-theft security level of security doors into four levels. Security doors with different security levels are all in terms of safety performance. Different, among them, the anti-theft door's anti-vandalism time has been more clearly defined. In anti-theft security performance, Class A security doors shall not be less than 30 minutes, Class B shall not be less than 15 minutes, Class C shall be not less than 10 minutes, and Class D shall not be less than 6 minutes. Laminated flooring new standard May implementation New standards for impregnated paper-laminated wood flooring, that is, reinforced flooring, have been formally introduced. The new standard has been adjusted in terms of its assembly height difference and surface wear-resistant rotation. The new standard specifies that the average height difference between the assembly is less than or equal to 0.10 millimeters, and the maximum height difference between the assembled parts is less than or equal to 0.15 millimeters, which is greatly improved compared with the original standard. There has also been a significant increase in surface wear resistance standards. The standard will be implemented from May 1st, which is expected to improve the assembly and wear resistance of laminate flooring. New standards for plastic doors and windows will be introduced The safety performance and service life of plastic doors and windows will be greatly improved. The reporter learned from relevant sources that the Plastics Branch of the National Product Standardization Technical Committee had recently revised the standards of plastic doors and windows, and obtained the approval of relevant state departments, which is expected to be promulgated in the near future. It is reported that compared with the original standard, the new standard has improved the bending elasticity of the profile. In addition, the profiles are graded according to the climate in the area of ​​use, so that the resistance of the profiles to embrittlement failures in specific climatic regions is greatly enhanced. In addition, the aging time of plastic profiles has been appropriately extended, which is expected to enhance the service life of plastic doors and windows.
