Salt Spray Testing

Salt Salt spray testing


Aerofin Laboratories Ltd are a UKAS & Nadcap approved salt spray testing laboratory.

Aerofin Laboratories can evaluate your product for susceptibility to corrosion through salt spray testing. The most commonly used method we offer is neutral fog (NSS), the standard method for salt spray testing. Along side this we have cabinets dedicated to modified salt spray testing in the forms of CASS & ASS. Copper Accelerated Acetic Acid salt spray and Acetic Acid salt spray.

An effective coating can provide corrosion resistance through the intended life of a part. Salt Spray testing creates a corrosive environment allowing us to assess the performance of  a protective finish. This process allows evaluation of corrosion in a shortened period of time, according  to a given specification.

Our laboratory has a large capacity for Salt Spray testing. We cater not only for a large volume of test pieces but also for test pieces which are over-sized or irregular in shape.  Maximum component size- 2000 x 1000 x 1175mm. Current standard salt spray test piece capacity is in excess of 1000 at any one time.

Aerofin Laboratories can offer photographic support incorporated within laboratory reports for salt spray.

During salt spray testing it is possible for the appearance of the test piece to change significantly due to the corrosive nature of the test. Aerofin can incorporate photographs of test pieces into laboratory reports providing a permanent visual record. Visual records are becoming requested increasingly when test pieces exhibit evidence of corrosion. Photographs can also assist the customer in determining why the test piece has corroded, allowing for a course of corrective action to be established.
