In a bid to make cars safer and more durable, International Centre for Automotive Technology (ICAT) has proposed a salt spray test for locally manufactured cars. This test is a common practice internationally.

Salt spray test is a common test for determining the corrosion resistance of the base material. The Ministry of Road Transport and Highways (MoRTH) had sought ICAT’s opinion on its proposal to make the usage of 70% galvanised steel for car body panels mandatory.

In India, safety of passenger cars is generally evaluated by presence of air bags, seat belts, shock absorbing devices, etc. However, it does not include corrosion resistance as one of the crucial factors for safety of cars.

Automakers in India use 30% galvanised steel for vehicles manufactured for domestic sales. Such steel is more susceptible to rusting, which reduces the car’s structural strength and stability. As the quality control in export markets is far more stringent, the export models use 70% galvanised steel.
