Great things happen when the world agrees. The corrosivity categories can be assessed in terms of the most significant atmospheric factors influencing the corrosion of metals and alloys. WBDG is a gateway to up-to-date information on integrated 'whole building' design techniques and technologies. In addition, the actual environment that affects a specific material or system correlates directly to the conditions of the micro-environment that it experiences (the "local environment" that occurs on the surface of the material or system), which can vary even over small distances. Using the NOAA database and Google Maps API, the ICCET automatically finds the nearest weather station and evaluates the weather data for completeness within the given data completeness range. As noted by Dr. Dave Rose in his Cumulative Corrosion Damage Model PhD Dissertation, the "principle advantage of using hourly data/calculations is that the effects of diurnal and seasonal temperature cycles and related changes to relative humidity are explicitly considered." Environmental severity is defined as the corrosivity of the local environment of a given location or region. In some situations, a DoD installation may be large enough to fit into more than one ISO Category. Part 1: Determination and estimation of indoor corrosivity. The user simply inputs: Figure 2 below shows an example of the ICCET Interface. None of the available methods establish severity indices for all of the materials and components used in DoD weapon systems and facilities (e.g., metals and alloys degrade differently than electrical components when exposed to the same environmental stressors). These tools can be used to estimate ISO Corrosivity Categories, calculate Wood Decay Hazard Index, overlay various corrosion data and severity indices using interactive maps, view animated maps of monthly corrosivity, and obtain air pollution and weather data from NOAA and EPA databases. At present, this is not possible on a large scale outside of laboratory testing or sites with active environmental or corrosion monitoring solutions.
