BGD 876 In-cabinet Exposure Condensation Chamber is designed according to ISO 6270-2¡¶Paints and varnishes -- Determination of resistance to humidity -- Part 2: Condensation (in-cabinet exposure with heated water reservoir)¡·. This standard is different with Part 1“Continuous condensation” , but defines three cyclic program£ºCH£¨Condensation atmosphere with constant humidity£©, AHT£¨Condensation atmosphere with alternating humidity and air temperature£©,AT£¨Condensation atmosphere with alternating air temperature£© to simulate different humidity environment.
It can give much better supplements and explanation for corrosion degree and defect types of coating used in different environment. Comparing to Part 1---single-sided exposure, this method add a condensation atmosphere with alternating humidity and air temperature, and mainly used to evaluate paints anti-corrosion ability under different environment.
