Premium models can perform the same basic salt spray tests as Standard models, but in addition are equipped with extra features which enable them to undertake ‘modified’ tests such as ASTM G85
Here conventional salt spray is usually combined with one other climate, in a two-part cycle. For example: salt spray and condensation humidity (SWAAT) or salt spray and drying (PROHESION).
Performances :
- Temperature range: Adjustable from ambient to +50°C/+122°F
- Salt spray fall-out rates: Adjustable from 0.5 to 2.5 ml per 80 cm2 per hour
- Wetting mode (Premium chambers only): Adjustable from ambient to +50°C/+122°F
- Drying mode (Premium chambers only): Adjustable from ambient to +50°C/+122°F
Features :
Premium models have the same features as Standard models plus:
- Touch-screen, full color user control interface, using intuitive icons for ease of programming and use.
- RJ45 communications port for connection to a local area network (LAN) for logging and remote programming via a computer running optional Ascott software (ACC120).
- A real-time, user configurable ‘clock’ to enable different test samples to have their exposure time monitored separately, with alarms to warn when preset test times have been completed.
- Immersion heater housed in the base of chamber enables high humidity condensation conditions to be created, if required.
6 different model sizes:
- 120 Ltr (4.2 cu ft)
- 450 Ltr (15.8 cu ft)
- 1000 Ltr (35.3 cu ft)
- 1300 Ltr (45.9 cu ft)
- 2000 Ltr (70.6 cu ft)
- 2600 Ltr (91.8 cu ft)
Standards
Standard and Premium : ASTM D1735, ASTM B117, ASTM B287, ASTM B368, ASTM G85 annex A1, MIL-STD-202 (USA Military),MIL-STD-750 method 1046 (USA Military,) MIL-STD-810G (USA Military).
Premium only : ASTM D2247 (not120 Ltr),ASTM G43, ASTM G85 annex A2, ASTM G85 annex A3, ASTM G85 annex A4, ASTM G85 annex A5, ASTM G5894.
Capable of performing many other International Norms
Standard models are designed for continuous salt spray tests, conducted at a single user-adjustable temperature, such as ASTM B117, ISO 9227, JIS Z 2371 etc. They may be used with pH neutral salt solutions (NSS) or test solutions acidified by the addition of Acetic Acid (ASS) or Cupric Acid (CASS).
