Which test is designed to evaluate the durability of ceramic tile installation systems?

The Robinson Floor test is specifically designed to assess the durability and performance of ceramic tile in various environments. It simulates the conditions the tile would face when subjected to foot traffic and other stresses typically encountered in residential and commercial settings. This test takes into account factors such as deformation, wear, and the overall stability of the tile installation over time, making it a comprehensive evaluation of the tile's performance.

In contrast, while the other options serve important purposes, they focus on different aspects of tile properties. For instance, ASTM C1028 measures the slip resistance of floor tiles, which is crucial for safety but does not directly pertain to durability in the context of installation. The Mohs Hardness test assesses the scratch resistance of materials, providing insight into the hardness of the tile rather than the performance of the installation system. The Bending Strength test evaluates the load-bearing capacity of the tile itself, which is important but does not encompass the overall durability of the installation as a system. Therefore, the Robinson Floor test stands out as the correct choice for evaluating the durability of ceramic tile installation systems.
