Test variants according to DIN EN ISO 6270-2
- CH – Constant condensed water climate
- AT – Alternating climate with condensed water (change of the air temperature in the chamber)
- AHT – Alternating climate with condensed water (alternation of air humidity and air temperature in the chamber)
Test method
During the test procedure, demineralised water heated to +40°C evaporates in a protected climatic chamber and condenses on the surface of the coated test specimens under specified ambient conditions.
Fully automatic condensed water test
Instruments such as the ERICHSEN HYGROTHERM 519 Smart are additionally equipped with a touch screen. Via the user-friendly menu, the required test parameters are set, which ensure a fully automatic or manual sequence for temperature control, soil water filling, soil water drainage as well as aeration and deaeration. A flow meter ensures the exact and fully automatic filling of the pre-set water quantity. In addition, the HYGROTHERM 519 Smart is equipped as standard with a test chamber illumination for a precise view of the test inside the test chamber even in low light conditions.
For testing in atmospheres containing sulphur dioxide (SO2) according to DIN EN ISO 6988, an electronic gas dosing unit is optionally required.
ERICHSEN testing equipment
With ERICHSEN humidity chambers it is possible to measure corrosion through the condensation water climate. The condensation water test is the basis for determining surface corrosion. ERICHSEN condensation water test chambers are designed for standardised individual and mass testing of small and large volume components according to standards such as DIN EN ISO 6270-2.
