ISO 6988 Corrosion of Metals by Humid Atmosphere
The ISO 6988 standard provides a method to determine the resistance of metals and their alloys to atmospheric corrosion in humid environments. This testing is crucial for industries where materials are exposed to high humidity, such as building and infrastructure sectors, particularly in regions with high rainfall or coastal areas.
Humidity can significantly impact the durability of metals used in construction and infrastructure projects, leading to premature degradation and increased maintenance costs. Understanding this effect helps in selecting appropriate materials that can withstand environmental challenges effectively.
The test involves exposing metallic specimens to a controlled humid atmosphere for an extended period under specific conditions defined by ISO 6988. The exposure duration varies depending on the desired outcome, but it typically ranges from several weeks to months. After exposure, the specimens are visually inspected and weighed to assess the extent of corrosion.
Materials tested using this method include structural metals like steel, copper alloys, aluminum, and stainless steel. The test is particularly relevant for components used in building facades, roofs, and infrastructure elements such as bridges, pipelines, and seawater systems.
