automotiveBecause cars are an integral part of our daily routine, it’s easy to forget that these vehicles are complex pieces of machinery. For every unit produced, car companies will shell out millions of dollars on conceptualization, design, prototypes, and even marketing.  But the expenses don’t stop there. To make sure that their cars aren’t just flashy and fast, but are also reliable and road-worthy, car companies subject each unit to undergo a series of rigorous tests.

Companies invest heavily in automotive testing services to make sure that every single component of the vehicle is operating the way it should be and will last for as long as intended.

Although vehicle recalls can still happen for a variety of reasons, strict and thorough automotive testing have drastically reduced product recalls, with 2017 seeing fewer recalls than 2016, and experts predicting an even lower number in 2018 and beyond.

Advances in technology have allowed laboratories to test vehicles in more comprehensive ways than before. Here are some tests that automotive testing services employ to make sure your car runs safely and efficiently.

Tension and Compression Testing

This test is applied to a variety of car components: from tires and axles to cables and wiring. Because it’s hard to accurately predict the mechanical behavior of certain automotive materials, testing services often use tension and compression testing on small batches of crucial components.

As the name suggests, tension and compression testing look for two things: tensile strength, and compression strength.

Tensile strength measures the ability of a material to stretch without breaking, while compression strength measures a material’s ability to withstand weight and pressure that would cause it to reduce in size.

Vibration Testing

Vibration testing is used to test the reliability and durability of an automotive part by subjecting it to varying degrees of vibrations. These vibrations are calibrated in such a way that they can reproduce a number of years’ worth of wear-and-tear in a matter of minutes.

This is of particular importance to automotive companies. Because vehicles go through different types of terrain, it’s important to know how the vehicle will respond to the different types of vibration. This also helps companies analyze how much shock their vehicle can take.


Metallography takes a close look at the physical structure of materials, particularly automotive alloys. Using a microscope, testing services will analyze the exact composition of a metal, and determine if that particular batch is fit for production. The materials being tested are usually prepared through a variety of methods such as etching, grinding, and polishing. Once ready, the material is subjected to a series of mechanical and chemical tests, and the results are inspected under an electron microscope.

Car companies use this test to determine whether the material they are using for their vehicle is light-weight, durable, and roadworthy.

There are many more tests that are used to determine how strong vehicles are, and to allow car companies to avoid recalling their products.
