The Renault D42 1775 standard, developed by the French Renault automobile company, describes the requirements for determining the abrasion and scratch resistance of plastic parts used in the interior and exterior of vehicles.
In general, the wear resistance of plastic is high. The test method for wear is actually quite simple. Abrasion resistance is measured by moving a rubber test piece across the surface of an abrasive plate mounted on a rotating drum. It is expressed as volume loss in cubic millimeters. Very high values represent greater loss of rubber to the surface, which means a lower resistance to abrasion. The lower the value, the better the wear resistance. A material with good wear resistance will last longer.
Abrasion resistance refers to the ability to withstand wear and tear caused by mechanical parts and repetitive friction situations.
Low-friction, wear-resistant, hard-wearing plastics used in applications requiring high performance and superior mechanical properties are used inside and outside of vehicles. The wear resistance of the plastic material used for industrial components must be able to perform under the most abrasive conditions in real-world applications.
Abrasion is a type of wear that causes material to deteriorate through friction when it rubs against each other or slides. Friction is a measure of the resistance to motion and energy loss when two surfaces interact. The friction coefficient is a term that measures the ratio of the frictional force when two surfaces interact with a numerical value. A high value indicates a large friction force.
Hardness is defined as the resistance of a material to plastic deformation such as scratching, cutting or stinging. Plastics are used for applications that require frictional contact with mating metal surfaces. Some types of plastic offer exceptional wear resistance to scratching.
Among the numerous test, measurement, analysis and evaluation studies it has given for businesses in various sectors, our organization, with its trained and expert staff and advanced technological equipment, aims to determine the abrasion and scratch resistance of plastic parts used in the interior and exterior of vehicles, within the scope of Renault D42 1775 standard. It also provides testing services.
