What classification does unglazed quarry tile fall under?

Unglazed quarry tile is classified under Tile Test D1. This classification is specifically designated for certain types of unglazed tiles which are typically made from natural clay and are designed for various applications, including both interior and exterior use.

Tile Test D1 focuses on defining the performance characteristics related to the slip resistance and durability of unglazed tiles, making them suitable for areas with high foot traffic and exposure to moisture. This standard is essential because unglazed quarry tile is valued for its natural finish, robustness, and ability to provide a good grip, which is particularly important in environments where safety is a concern, such as kitchens and bathrooms.

Understanding this classification helps ensure that the proper testing and standards are applied, promoting safety and quality in tiling applications. Other classifications like A1, B1, and C might pertain to different finishes, materials, or intended uses that do not encompass the unique characteristics and applications of unglazed quarry tile. Thus, recognizing the appropriate classification assists installers and designers in choosing the right tile for specific environments.
