Automotive Interior Testing

Impact Resistance

Impact resistance testing on automotive interior parts is used to evaluate how well materials can withstand sudden impacts or collisions that may occur during regular use or in accidents. This testing is done to ensure that plastic, metal or coatings on components like dashboard panels or door trims can absorb or resist impact forces without cracking, chipping, or breaking. Impact resistance testing involves striking a part with a controlled force using a specified weight or device, such as a pendulum or drop test apparatus, to simulate different impact scenarios. The part is then examined for damage, such as cracks, dents, or fractures, to assess its durability.
