Chemical testing for automotive :

Vehicles face latent threat each time they hit the road, although the inherent danger on roads cannot be eliminated completely, chemical testing of vehicles and its components can ascertain that they function to the best of their ability. We offer tests which provides highly accurate chemical analysis of metals, plastics and other non-metallic products to ensure that you vehicle adhere to stringent industrial standards and conform to the required safety rules and regulations.

Corrosion Testing :

Salt spray testing is the most widely practiced testing method for testing of automotive against normal environmental conditions, but the correlation between the test results of the salt spray test and real life corrosion of vehicle was not evident. Hence there was a need for a test in which vehicles could encounter simulated environments more close to real life conditions. This gave rise the cyclic corrosion testing, which could actually help identifying the life expectancy of an automobile under normal environmental conditions. Salt spray test continues to serve as a parameter which indicates the durability and quality of a vehicle and corrosion testing identifies the normal corrosion, a vehicle is likely to undergo in its operational life. We provide extremely accurate and reliable corrosion testing facilities where vehicle manufacturers test their produce against real-world corrosive environments.

Fuel Resistance Test :

Liquid fuels like petroleum and diesel are used to derive energy for operation and petroleum based products are used in the composition of motor oils in a vehicle. Therefore they are always prone to leakages and spillage of fuel and fuel based products. Fuels are highly flammable, hence it becomes inevitable for vehicle manufacturers to ensure that in case of spillage or leakage the vehicle is equipped to prevent potential ignition damage. Application of fuel resistant paints on the body of the vehicle is one way to deal with the potential hazard. We offer testing services in our laboratory facility to accurately examine the degree to which the protective paint can avoid inflammation of vehicle components in case of spillage or leakage.

Salt Spray test :

A large part of the automobiles are made up of metals like steel, aluminium and iron which often have to sustain the damage inflicted by environmental corrosive agents like water, moisture, mist, humidity and vapours. It is highly significant for vehicle manufacturers to ensure the quality of the metals and the protective coatings being used are durable enough to withstand these corrosive attacks. In our Laboratory facility we undertake testing services to measure the strength and sturdiness of the anti-corrosive film applied over the metallic components of the vehicles. Testing ensures that the protective film coated over the metals conform to the safety standards and adhere to the guidelines of the regulatory bodies.

Salt Fog Testing :

Salt fog is a type of spray test in which a vehicle is kept in a chamber where it is sprayed with salt fog incessantly at a particular temperature. This helps to evaluate its resistance power against corrosive salts and helps to determine durability of the protective film applied on the body of the vehicle and its counterparts. We offer highly reliable salt fog testing services to verify the suitability of the protective films on the vehicle in a particular simulated environment.

High Pressure Spray :

A form of spray testing, high pressure spray, is a method of testing vehicles against forceful water spray. This method testing ensures that the vehicle and its components are sturdy enough to sustain this force and does not face any kind of breakdown or component failures in such situation. Vehicles in day to day basis are cleaned with water splash or spray which sometimes enter internal components which are required to be free from water permeability, this test ensures no such situation arises. We offer high pressure testing services with adjustable volume, speed, range and pressure as per the requirement and suitability of the vehicle.

Flammability Tests :

Vehicles are highly prone to ignition as they are powered by fuel which is highly inflammable. Their internal components must be equipped sustain themselves in case of fire. Components like seat cushion, seat back, seat cover, seat belt, head rest, arm rest, movable convertible top, all decorative panels and many others must have the ability to safeguard themselves from fire as their flammability has direct effect on the safety of the people inside the vehicle. For vehicle manufacturers it is extremely important to ensure that components can resist fire to some extent as required by the regulatory and safety standards. At our laboratory facility we offer testing of components to ensure that they don’t burst into flames as soon as they come in contact with source of fire.

Colour Fastness Test :

Over time the materials like textiles, leather and rexine used in seat covers, arm rests and decorative panels deteriorates and their colours fades and texture desecrates. This majorly hinders the look of the interiors. To ensure that the fabrics and materials being used maintains its colour and lustre for a long period of time, it is essential for vehicle manufacturers to subject them to a simulated environment where they are made to endure the damage cause by regular wear and tear. This facility is provided in our testing laboratory which helps determine the materials resistance against usual environmental damage and ability to sustain its colour.

Alkali Resistance :

Automobiles like any other substance or article needs cleaning and washing from time to time. Effective cleaning involves spraying of cleansing agents which contain strong alkaline substances. Spraying of alkaline cleansers on high pressure tends to wither the surface of anodized aluminium coating over the metallic bodies of the vehicles. Anodising is a preventive measure through which aluminium components can be saved from corrosive impacts of alkaline substances. This process involves creating a coating over the metal by oxidising it through undertaking electrolysis in sulphuric acid. We in our laboratory facility offer services in which we determine the strength of the protective layer formed through this process and its ability to resist corrosive impacts inflicted by alkaline substances.
