ActiveCorrosion of metals and alloys—Black box exposure test method
金属和合金的腐蚀 黑箱暴露试验方法
Application Summary AI generated
This standard specifies a method for conducting black box exposure tests to evaluate the corrosion resistance of metals and alloys in natural atmospheric environments. It is primarily applied in materials testing and quality control for industries such as automotive, construction, and outdoor infrastructure, where components are subjected to sheltered or partially enclosed conditions that promote moisture retention and accelerated corrosion. The test simulates real-world degradation under covers, eaves, or enclosures, helping engineers select appropriate materials for long-term durability.
