This test attempts to address two major drawbacks in existing mar tests such as Test Methods D1044, D3363, D5178, D6037, and D6279, namely:

Measured damage is caused by hundreds of contacts with differing contact geometries making it difficult or impossible for mechanical quantities (force, displacement) at the contact points to be reliably determined.

The damage is evaluated using subjective visual assessments, which provide only a qualitative sense of wear with little information about mar mechanisms.

This test provides a quantitative assessment of a paint coating’s mechanistic aspects of scratch/mar behavior in various conditions. The ability to control testing variables such as rate and temperature allow the study of the scratch/mar behavior in a variety of environments.

This test method is particularly suitable for measurement of paint coatings on laboratory test panels.

The accuracy and precision of scratch/mar performance may be significantly influenced by surface nonuniformity and irregularities.
