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.
ERICHSEN Humidity ChambersFrequently Asked Questions about Condensation Water Testing
What is condensation water testing?
Condensation water testing (also known as the humidity test) is used to evaluate the corrosion susceptibility of surfaces and materials under defined humid climate conditions – such as according to DIN EN ISO 6270-2 CH.
What are the advantages of this method?
- Standardized testing according to international norms
- Proven method for analyzing corrosion behavior and climate resistance
- Suitable for single and mass testing
Which models for condensation water testing are available?
- HYGROTHERM 519 – Cabinet design, manual, with 300 l test volume
- HYGROTHERM 519 Smart – Cabinet design, fully automatic with touch operation and optional remote access
- HYGROTHERM 529 / 1000 l and 2000 l – Test chamber, for large-volume tests in stationary design
Which standards define condensation water testing?
Testing is based on:
- DIN EN ISO 6270‑2 CH – Constant climate with condensation water
- DIN EN ISO 6270‑2 AT – Alternating climate with condensation water (variation of air temperature in the test chamber)
- DIN EN ISO 6270‑2 AHT – Alternating humidity and temperature climate with condensation water
- Other standards: DIN 50958, ISO 11503, ASTM D2247, BS 3900 Part F2
What test volumes are available?
- 300 l for HYGROTHERM 519 (Smart) (manual/fully automatic)
- 1000 l or 2000 l for HYGROTHERM 529 (stationary)
The volume determines the number and size of samples that can be tested simultaneously.
What are typical applications for condensation water testing?
This testing method is used in:
- Corrosion protection testing of coated materials
- Quality assurance in the paint, automotive, construction, or metal industries
- Research and development on material resistance under humid climate conditions
