CONTINUOUS CONDENSATION HUMIDITY CHAMBER according ISO 6270-1 and ASTM D4585
For testing water resistance of coatings using controlled and continuous condensation.
Condensation is produced by exposing one surface of a coated specimen to a heated, saturated mixture of air and water vapor, while the reverse side of the specimen is exposed to the cooling effect of room temperature air.
Water set up temperature is 40 °C to match condition imposed by ISO 6270-1 standard.
Standard speaks about one air temperature, measured at 25 mm from sampling, uniform and constant at ±2 °C and not less than 35 °C, meaning a temperature of 37 °C ±2 °C.
Ambient temperature outside of apparatus must be held at 23 °C ±2 °C.
This test is also known as the Cleveland condensation test.
This test is primarily intended to determine the water resistance of organic coatings by controlled condensation.
Condensation is produced by exposing one surface of a coated specimen to a heated, saturated mixture of air and water vapor, while the reverse side of the specimen is exposed to the cooling effect of room temperature air.

Standard extract
This European Standard supersedes EN ISO 6270:1995.
5.4 The top of the bath shall be designed so that the test panels are held at the preferred angle of (60 ± 5)° to the horizontal to permit drainage of condensed water, and shall be such that water draining from one panel does not come into contact with another.
An angle of (15 ± 5)° may be used on old equipment if specified.
ASTM D4585
5.2 Specimens should be inclined at 15° to 75° to the horizontal and arranged so that condensate is returned to the water.
