Good News! Two National Standards Compiled By 3H  Architectural Hardware Were Officially Released

Recently, according to the State Administration for Market Regulation (National Standardization Administration Committee) Announcement No. 20 of 2023, the national standards "Plastic Doors and Windows for Buildings" GB/T 28886-2023, "Thermal Cycle and Structure of Building Curtain Walls" co-authored by 3H Building Hardware GB/T 43496-2023 "Exposure Testing Method" has been officially approved and released and will be implemented on July 1, 2024. These two standards are under the jurisdiction of the National Technical Committee for Standardization of Building Curtain Walls, Doors and Windows, and the competent authority is the Ministry of Housing and Urban-Rural Development.

The national standard GB/T 28886-2023 "Plastic Doors and Windows for Construction" completely replaces: GB/T 28886-2012, GB/T 28887-2012. This standard specifies the classification, specifications, series and marking of plastic doors and windows for construction, and general requirements. , technical requirements, test methods, inspection rules, markings and accompanying documents, packaging, transportation and storage. Suitable for PVC-U plastic doors and PVC-U plastic windows for construction.

The national standard GB/T 43496-2023 "Detection Methods for Thermal Cycle and Condensation of Building Curtain Walls" stipulates the general requirements for thermal cycle and condensation detection methods of building curtain walls, detection principles, detection devices, test pieces and installation, detection methods and detection reports . It is suitable for laboratory testing of thermal cycle and dew condensation on building curtain walls. The test object is limited to the building curtain wall specimen itself and the connection structure between its structures.

As an effective measure to enhance the industry's voice, 3H Architectural Hardware has participated in the drafting and formulation of standards related to building doors, windows, and building curtain walls since many years ago. Up to now,3H Building Hardware has obtained nearly 500 patents and is a national enterprise with superior intellectual property rights. It has participated in the compilation of 7 national standards, 13 industry standards, and 7 group standards. It has also formulated a number of corporate standards that are higher than industry standards. .

By participating in the formulation of technical standards such as national standards, 3H Architectural Hardware can not only better share its professional knowledge and experience with the entire industry, but also reflect 3H Architectural Hardware's technical strength in this field. In the next step, 3H Hardware will continue to promote the integrated development of technological research and development and standardization, and actively participate in the formulation and promotion of relevant standards around key areas such as building doors, windows, and building curtain walls, in order to improve product quality and promote continuous innovation and high quality in the industry. Development contribution to 3H Hardware.
