GB/T 28289-2012

This standard specifies the test methods for evaluating the composite performance of aluminium alloy thermal barrier profiles, including mechanical and thermal properties such as shear strength, tensile strength, and thermal cycling resistance. It is primarily applied in the building and construction industry for quality control and performance verification of thermal break window and door frames, curtain walls, and other architectural profiles that require enhanced energy efficiency. Manufacturers, testing laboratories, and procurement engineers use this standard to ensure the structural integrity and insulation effectiveness of thermal barrier profiles under simulated service conditions.
