GB/T 28289 - 2012 focuses on the composite performance testing of aluminum alloy thermal insulation profiles. It plans the preparation of samples in detail, from profile interception to processing, to ensure that the samples can reflect the true performance of the product. Precise technical parameters are given for various types of test equipment, such as instruments used for mechanical properties testing. In the test process, key operations such as loading methods and measurement procedures are strictly standardized. According to this standard, the composite performance of aluminum alloy thermal insulation profiles in different dimensions can be comprehensively and accurately determined, providing reliable material selection reference for construction, industry and other fields, helping enterprises optimize product design, improve product mass, and meet the market demand for high-performance aluminum alloy thermal insulation profiles.
