BGD 876 In-cabinet Exposure Condensation Chamber

Description

BGD 876 In-cabinet Exposure Condensation Chamber

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：CH（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.

Condensation Test Atmospheres

Test   Atmosphere			Cycle   Duration		Conditions   in working chamber after reaching equilibrium
Type		Code	Test Period（s）	Total	Air   Temperature	Relative   Humdity
Constant-humidity   condensation atmosphere		CH	From warm-up to end of   exposure	—	（40±3）℃	Approx.100% with   condensation on test specimens
Alternating   condensation atmosphere	With   alternation of humidity and air temperature	AHT	8h including warm-up	24h	（40±3）℃	Approx.100% with   condensation on test specimens
			16h including cooling-d		18℃ to 28℃	Approaching ambient
	With alternation   of air temperature	AT	8h including warm-up	24h	（40±3）℃	Approx.100% with   condensation on test specimens
			16h including cooling   down（chamber   closed）		18℃ to 28℃	Approx.100%（approximately saturated）

BGD 876 In-cabinet Exposure Condensation Chamber

◆ Designed with automatic ventilator, can control chamber ventilation automatically.

◆ Operator can set three different working conditions：humidification, cooling with ventilation, cooling without ventilation and its corresponding temperature & running time. Any program including total test time and cycle times can be set freely.

◆ Automatic water supply

◆ Protector for water temperature ceiling

◆ A glass observation window is designed in chamber, operator can observe specimens test status directly.
