This standard specifies an accelerated aging test method for evaluating the performance changes of vulcanized rubber under simulated solar radiation, temperature, and water spray conditions using an open-flame carbon arc lamp as the light source. The standard details the test equipment (such as the carbon arc lamp aging chamber), test conditions, performance evaluation indicators for specimens (such as changes in tensile properties, color changes, cracking, etc.), and specific test procedures. By periodically applying light exposure, water spray, and temperature adjustments, this method simulates and accelerates the outdoor aging process of materials to provide a basis for assessing product durability.
