Ascott Corrosion Test Chambers

Controlled corrosion testing for materials, coatings and components

Ascott corrosion test chambers provide controlled laboratory environments for evaluating the corrosion resistance of materials, coatings and finished components. The range includes salt spray chambers for traditional continuous salt-fog testing as well as advanced cyclic corrosion chambers capable of automatically exposing specimens to changing environmental conditions.

Salt spray and cyclic corrosion testing

Ascott chambers are available for conventional salt spray testing and more complex cyclic corrosion testing. Salt spray chambers create a controlled corrosive salt-fog environment, while Cyclic Corrosion Test (CCT) chambers can automatically combine salt spray with other environmental conditions such as humidity, wetting and drying.

Programmable cyclic corrosion environments

Ascott CCT chambers are designed to reproduce changing corrosive environments through programmable test sequences. Standard operating modes include salt spray, condensation humidity (wetting),forced-air drying, controlled temperature, ambient drying and controlled humidity. These conditions can be programmed in different sequences and repeated automatically to meet the requirements of the selected test procedure.

Wide choice of chamber capacities

The cyclic corrosion chamber range is available in multiple capacities to accommodate different specimen sizes and laboratory requirements. Current Ascott CCT chamber sizes include 300, 400, 450, 1000, 1300, 2000 and 2600 litres. This allows laboratories to select an appropriate chamber for anything from smaller test specimens to large assemblies and components.

Precise control and straightforward operation

Current CCT chambers feature a 7-inch full-colour touchscreen controller with built-in language selection and large-capacity memory. Sensors continuously monitor chamber conditions, while programmable controls automate transitions between the different stages of a corrosion test. An RJ45 communications port also supports connection to a local network for data logging and remote programming when used with optional Ascott software.

Designed for practical laboratory use

Features such as a pneumatically operated Easy Open canopy, automatic fresh-air purge before opening, a large separate salt-solution reservoir and a low loading threshold simplify routine operation. A dry-seal gasket and corrosion-resistant chamber construction are designed for the demanding environment associated with accelerated corrosion testing.

Compatible with numerous corrosion test methods

Depending on the selected chamber, configuration and accessories, Ascott systems can be configured for a wide range of international salt spray and cyclic corrosion methods. These include traditional salt spray procedures such as ASTM B117 and ISO 9227 as well as cyclic methods requiring controlled combinations of salt spray, wetting, humidity and drying. Chamber configuration should be selected according to the exact standard and test conditions required.
