The manufacturer's technical documentation shall specify the choice of the materials and/or the type of the surface treatment. Surface treatment system for carbon or low-alloy steels (e.g. according to EN 10025) shall be chosen according to the classification categories given in Table 1. Test assessment and test procedures are the responsibility of the manufacturer. NOTE Table 1 may be used to define the corrosion category and help the mounting kit manufacturers to define the surface treatment for corrosion protection. Table 1 — Environmental corrosion categories Typical environments Corrosion category Exterior Interior C2 (low) Atmospheres with low level of pollution. Mostly rural areas. Unheated buildings where condensation may occur, e.g. depots, sport halls. C3 (medium) Urban and industrial atmospheres, moderate sulphur dioxide pollution. Coastal areas with low salinity. Production rooms with high humidity and some air pollution, e.g. food-processing plants, laundries, breweries. C4 (high) Industrial areas and coastal areas with moderate salinity.
