CCT-1 and CCT-1L are corrosion test apparatus for accelerated testing involving cyclic exposure to salt spray, dry, wet, and salt immersion conditions of metallic materials and coationfs (CCT-1L can also conduct low temperature test). As CCT-1 and CCT1-L can simulate accelerated degradation in excellent correlation with outdoor exposure, they are widely used in various industries, notably automobile and steel. The reference specimens specified in ISO 9227:2006 are used to verify performance of CCT-1 and CCT-1L.
