During use, automobiles undergo qualitative changes due to external environmental factors-aging, deformation, or damage from accidents-which gradually degrade their technical condition. To ensure safer operation of these premium vehicles, automotive inspection has become the most critical phase in production. Soft coating materials are predominantly used in vehicle interiors, and their performance characteristics directly impact practical applications; consequently, OEMs are imposing increasingly stringent requirements for testing these materials.
