Based on the Ascott CCT chamber, the Atmosfär is equipped with additional features to enable it to comply with the specific automotive test requirements of Ford and Volvo.
Such tests standard include:
- Ford CETP 00.00-L-467
- Volvo VCS 1027,149 (ACT-1)
- Volvo VCS 1027,1449 (ACT-2)
- Volvo STD 423-0014
- Volvo STD 1027,1375
- ISO 16701
- Scania STD 4319
- Swaying spray bar
Set high in the chamber, spray nozzles oscillate backwards and forwards to produce a fan shaped spray pattern that ensures test samples are ‘swept’ uniformly with spray of salt solution.
- Separate air conditioning unit
Combines refrigeration and dehumidification to extend the range of temperature and humidity control (down to -20°C/-4°F or -40°C/-40°F depending on the model) under programmable control
- High velocity vertical air-flow
High velocity air, from the separate air conditioning unit, passes vertically though the test samples, evenly from top to bottom, during the climate controlled testing phase.
- MAG-DRIVE™ – magnetically coupled
Spray bar drive system Enables quick spray bar removal from the chamber if conventional salt spray testing is required. With no drive shaft passing through the chamber wall, there is no risk of salt solution leakage and it is safe as it will stall if the spray nozzles are obstructed.
- Psychrometric Humidity Measurement Module
A mechanism unaffected by frequent cycles of extreme humidity, ensuring lifetime integrity of measurement. Provides a wider operating envelope, with improved performance at humidity levels around 95%RH.
- For added flexibility, Atmosfär chambers also retain the ability to perform conventional salt spray tests and Cyclic Corrosion Tests (CCT) in accordance with a wide range of international test standards.
