ISO 6270-2, DETERMINATION OF RESISTANCE TO CONDENSATION IN PAINTS AND VARNISHES.

CONDENSATION CHAMBERS

ISO 6270-2 (Determination of resistance to humidity. Part 2: Procedure for exposing test specimens in condensation-water atmospheres) establishes conditions and procedures for the conditioning of samples in order to evaluate the behaviour and defects that can develop when samples are subjected to high humidity environments. This test establishes 3 different types of atmospheres: CH - Condensing atmosphere with constant humidity; AHT - Condensing atmosphere with alternating humidity and air temperature; AT - Condensing atmosphere with alternating air temperature.

Normally, condensing chambers are presented in a vertical format with a capacity of approximately 300 litres, but... What happens when we want to test large parts? In this case, Dycometal's solution is the condensing chamber in horizontal format with a large width dimension in order to be able to introduce the largest samples. This horizontal design allows several samples to be positioned in parallel for testing. Volumes of 1000 or 2000 litres provide more than enough capacity to accommodate large specimen lengths.
