Specifications
The Cyclic Corrosion Test Chamber (CCT) combines traditional exposure to salt spray with a variety of other controlled climates, including variable temperature & humidity, to create an accelerated simulation of service life conditions, according to customer requirements. CCT is, therefore, particularly well suited to predicting product service life expectancy.
They come with the ability to create 4 distinct climates: 1. Salt spray; 2. Condensation humidity (wetting); 3. Air drying; 4. Controlled humidity. These may be programmed to occur in any sequence and be repeated automatically.
The Ascott CC450G comforms to the following standards:
- ASTM B117
- SAE J2334
- ASTM G85
nCATS has run various projects in the Ascott CC450G CCT chamber has been used in various research, student and consultancy projects from development of new sensors to electrochemical measurements of metals and coatings. Additionally corrosion of aircraft paints and comparison to environmental weathering has been explored.
Projects include:
- Improved Testing Methodologies for Evaluating the Performance of Paint Systems and Materials - Current testing methodologies for appraising the performance of coating systems rely on the use of standard tests which are often far removed from the environments that will be experienced in operational conditions.
