Surface Analysis


Colour Fastness Test:

Over time materials like textiles, leather and rexine used in seat covers, armrests and decorative panels deteriorate and their colours fade and texture deteriorates which majorly kills the look of the interiors. To ensure that the fabrics and materials being used maintain their 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 caused by regular wear and tear. This facility is provided in our testing laboratory which helps determine the material’s resistance against usual environmental damage as well as the materials ability to sustain its colour.

Dew Formation Test:

Automobiles have to operate in all kinds of weather conditions and therefore they have to be equipped to function in all such circumstances. Humid weather is one of the conditions which can cause failure in electronic devices. When there is high humidity in the weather, dew formation is a common phenomenon, which is evident. when you start observing moisture droplets within screens of the machine. when water vapours coming in contact with cold objects, they convert into liquid droplets called dew. Such dew formation when formed in-vehicle components, can hamper their functioning. In our laboratory facility. We test those vehicle components which are susceptible to failure when they get subjected to dew. We examine and determine the degree to which they can endure moisture in that form and function without problems.

Gloss Value test:

The bodies of vehicles are prone to damages like scratches, abrasions and paint chipping during their day to day operational life. This phenomenon causes the lustre and gloss of the paint coating on the outer body of the vehicle to get damaged. Gloss-less paints hamper the look of the exterior body of a vehicle. The gloss value of the paint applied on a vehicle can be measured by the amount of light reflected back when it is directed towards a given part in a particular angle. We in our state-of-the-art laboratory offer testing services to determine the gloss value of the paint coating applied over the components of vehicles.

Coating Thickness:

Zinc has intrinsic corrosion resistance properties, which make it an ideal material to serve as a protective film for steel and iron components in the vehicle. Zinc protective film is used on metallic components of the vehicles in various forms like zinc-rich paints, mechanical plating, electroplating, metallizing and hot-dip galvanizing. Measuring the thickness of the zinc enriched coating can accurately determine its effectiveness in resisting corrosion. In our testing laboratory, we offer services in which zinc protective films are accurately measured to determine their thickness and hence determine the service life of the metal it protects, which is indicated by the. coating thickness.

Electroplating Thickness:

Vehicle manufacturers are required to provide some kind of protective shield to the metallic components of an automobile, as they are at all times during operation, prone to abrasions, wearing, chipping and scratching. Subjecting metallic components to electroplating is one method to apply a protective layer over them to prevent corrosion. Electroplating is a process in which, through electrochemical procedures, a metallic layer is coated over a subject which is susceptible to corrosion. For vehicle components made up of iron, steel and aluminium, protective film of zinc is formed using this procedure. To ensure that this protective film is providing adequate safety from corrosive effects, we offer electroplating thickness test, in our state-of-the-art laboratory facility. The thickness of the layer of zinc formed through the electrochemical process can determine the extent to which it can help avoid corrosion effects.

Scratch Resistance Test:

An automobile in parked state or during operation, is always prone to scratches. Scratches can be caused by little things like, rubbing of small pebbles, sand or dirt against the body of vehicle. For vehicle manufacturers it becomes highly significant to ensure that the paint or the protective coating being applied over the components of the vehicle are able to resist these marks to some extent. In our state of the art laboratory facility we are equipped with instruments to determine the quality of the protective film against scratch resistance. We simulate an environment in which vulnerable components are subjected to scuffing and scratches, this helps identify the degree of utility, protective layers being used as serving.

Abrasion Resistance:

Vehicles operate in close proximity to each other and therefore minor accidents which results in scraping, scratching and abrading marks and patterns on their bodies are not an uncommon phenomenon. Hence it is inevitable for vehicle manufacturers to ensure that the components of vehicles, vulnerable to such accidents are equipped to bear and exhibit minimum damage from such accidents. For that purpose, we offer reliable tests in our laboratory for those vehicle components. Materials like plastic, glass, metal, rubber, textiles used in vehicle components are subjected to abrasive wear as a part of the resistance test. They must provide at-least a minimum level of protection in order to conform to the regulatory standards.
