Heat/ Thermal resistance test :

Environmental conditions are evolving globally and the temperatures are consequently rising. The sky high temperatures are causing major problems in automobiles. Over-heating reduces the battery’s life span, the air conditioning system gets overworked and causes excess stress to its engine, along with that the paint and protective film on the outer body of the vehicle fades and corrodes. It is essential for vehicle owners to evaluate the maximum thermal resistance a vehicle has and for that purpose we provide highly sophisticated thermal resistance testing facility which can subject vehicle to temperature range from 20ºC to 1200ºC as per requirement. We help ascertain the maximum resistance a vehicle has to environmental heating.

Thermal Cycle Test :

Thermal Cycle Test involves cycling of automotive parts from high temperature to low temperatures to test their durability. Vehicles in real life, may have to encounter varied temperatures and they are required to function to the best of their abilities in each temperature. To test vehicles for endurance against varied temperatures we offer thermal cycle test facilities where we provide accurate tests and analysis for the same. Our thermal cycle testers are equipped to simulate a wide range of temperatures between -30ºC to 80ºC, sufficient to test all sorts of vehicles.

Thermal Shock :

Extreme temperatures have adverse effects on vehicles and on their parts. In extremely hot weather the battery of the car gets over heated, the air conditioners get over worked which has considerable negative impact on its engine. In cold weather the motor oil thickens, which causes the engine to get all worked up, along with that battery efficiency also drops. We provide thermal shock testing services to test your vehicle for its capability to withstand sudden changes in temperatures. Vehicles are exposed to extreme temperatures in our thermal shock chambers to examine their power to endure thermal stress.

Shock pulses test :

Vehicles on road are prone to various shocks and collisions which can be fatal for the vehicle as well as the driver. We provide highly reliable tests in which we subject the vehicle to shock pulses and evaluate its degree of durability. Through this test we ensure that vehicles conform to industrial standards and adhere to safety regulations. A vehicle unprepared for shocks will encounter deformities, loosened bolts and displacements of adjacent circuits when subjected to pulses.

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 a vehicles. Zinc protective film is used on metallic components of a vehicle 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 to which it provides protection. Coating thickness is an indicator.

Electroplating Thicknes :

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 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 corrosion effects, we offer electroplating thickness test, in our state of the art laboratory. Thickness of the layer of zinc formed through the electrochemical process can determine the extent to which it can help avoid corrosion effects.

Ingress Protection :

Vehicles operate outdoors which makes them vulnerable to the impacts from ingression from sand, dust, dirt, water and other foreign substances. These materials when enter the internal components of an automobile, they cause hindrance in their functioning. For vehicle manufacturers it is essential to ensure that components that they manufacture have adequate resistance to such ingressions. We in our sophisticated laboratory facility test vehicle components are enabled to provide protection against dust, sand particles and water droplets.

Ingress Protection Testing

Scratch Resistance Test :

An automobile in parked state or during operation, is always prone 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 become 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 are serving.

Scratch Resistance Test

Abrasion Resistance :

Vehicles operate in close proximity to each other and therefore minor accidents which results in scrapping, scratching and abrading marks and patterns on their bodies is 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.
