Try our tool below to assess your ISO9223 C1 through C5 and CX environments. These scores are based on a variety of environmental conditions, including temperature, relative humidity, atmospheric sulfates, and atmospheric chlorides. For simplicity, we break them into half increments, so a C1.5 environment is between a C1 and a C2, but closer to a C2 environment.
