Salt Spray Corrosion Testing Laboratory | Sigmatest

Salt Spray Testing Lab



A major part of any automobile is made up of steel, iron or aluminium and so is prone to corrosion by moisture, humidity, mist, water vapours or water. We conduct salt spray testing in our laboratories to determine the strength & sturdiness of the anti-corrosive film that is applied over the metallic parts of the vehicle.

Technical experts at Sigma adjust the environmental conditions such as temperature & humidity, to simulate specific weather and working conditions. It is important to assure that the metal employed is of good quality and protective coating applied to it is durable enough to withstand the harmful effects of corrosion.

Why test for corrosion resistance?

To determine the corrosion resistance of the finished product metal

To measure corrosive inclination on the scratching of the metal surface

To detect deformation due to corrosion and the adhesion of the coating

Evaluate corrosion resistance in a humid environment (temperature, salt fog, moisture)

The salt spray test procedure is conducted in a salt spray room or cabinet, which have both temperature and humidity regulators. Salt spray test standards are designed in a way to examine the deterioration level of the material under consideration.

The Salt spray test helps ascertain resilience levels of metal objects and surfaces, the material when these comes in contact with salt. Through this accelerated corrosion test, we examine the versatility of the test sample in the presence of salt.

We conduct Salt spray testing in our labs to ensure that the metal coating on your automotive components is designed as per the guidelines laid by the regulatory bodies and safety standards.
