Method of Accelerated Evaluation of Durability of Aluminum Profile under the Influence of Climatic Factors

The method of accelerated evaluation of durability of aluminum profiles of translucent enclosing structures (TES) for facade glazing under the influence of climatic factors is proposed. The essence of the method is to conduct laboratory tests with cyclic effects of variable positive and negative temperatures, humidity, ultraviolet radiation, poorly aggressive chemical media (solutions), and salt fog. The method is developed with due regard for the requirements of GOST 22233–2001 on profiles pressed from aluminum alloys for translucent enclosing structures. The criteria for assessing the durability of aluminum profiles in terms of adhesion, color characteristics by the coordinate method, gloss, bearing capacity of the connection zones at shear and transverse tension, the requirements for accelerated testing, testing equipment, methods for evaluation of test results are established. On the basis of the developed method, the standard of NIISF RAACN was created.
