Scratch and Mar Resistance of Automotive Plastics - Determination of

This procedure describes the method for determining the scratch and mar resistance of molded-in-color automotive plastics by use of a linearly-oriented, one-pass, multi-fingered scratching device.  This method is appropriate in the evaluation of mar resistance of molded-in-color automotive thermoplastics used for interior or exterior in ornamentation or trim applications.

Scratch and Mar - Resistance of Molded-In-Color Plastic Components

This standard establishes the minimum requirements for engineering acceptance of scratch and mar resistance of molded-in-color plastic parts.  The ultimate objective is to produce molded plastic parts which resist scratching and marring and thus are not aesthetically detracting from the vehicle and/or hinder the quality appearance of the vehicle.  Additionally, this standard is to verify that after the molding process that molded-in stresses are not adversely affecting the resistance to scratching or marring of the material.

Testing Method of the Scratch Resistance of Interior Polypropylene Resin Parts

This NES specifies the methods for testing the scratch resistance (hereinafter referred to as test methods) of automotive interior resin parts (hereinafter referred to as parts). These test methods are applied specifically to the parts made of polypropylene (hereinafter referred to as PP) and its compound materials (hereinafter referred to as PPC) of interior resin parts. These test modes shall not be applied to a painted portion, or a surface coated plastic part.
