LOCKING PORCELAIN TILE SPECIFICATIONS
3 of 3
CLASS TWO
Tile in this class may withstand soft-soled and some normal foot trac provided the dirt and/or
other abrasives are kept to a minimum. Class II tile should not be used in areas with direct access to
the outside, large amounts of foot trac, or areas exposed to abnormal footwear. See Coecient of
Friction for installation-specific details.
CLASS THREE
Tile in this class may withstand normal footwear and regular trac, with some dirt and/or other
abrasives present in limited quantities. Tile in this class may be used in light commercial installations
with limited foot trac and with no direct access to the outside including residential kitchens and
hallways, with limited trac from the outside. See Coecient of Friction for installation-specific
details.
CLASS FOUR
Tile in this class may withstand heavier amounts of trac with greater amounts of dirt and/or other
abrasives present including commercial kitchens and areas with regular trac from the outside. See
Coecient of Friction for installation-specific details.
CLASS FIVE
Tile in this class may withstand constant foot trac with larger amounts of dirt and/or other
abrasives including airports, malls, and other commercial walkways subject to high volumes of foot
trac and constant trac from the outside. See Coecient of Friction for installation-specific details.
Coecient of Friction, DCOF Wet Areas (Minimum 0.42)
Water, oil, grease or other fluids create slippery conditions. When installing floors in areas with exposure to these
conditions, a minimum DCOF value of 0.42 is required. Additionally, extra caution is required with regards to product
selection and proper maintenance. Visit www.tcnatile.com for complete information regarding the DCOF Acutest
sm
test
method and values.
Industry Standards
The American Society for Testing and Materials (ASTM) and the American National Standards Institute (ANSI) are
nationally recognized organizations, which identify and develop industry test methods and technical standards.
Neither ASTM nor ANSI establish an industry standard identifying a minimum COF value whereby ceramic tile may
be labeled “slip resistant”. All Standard Grade ceramic tile products manufactured by or for Daltile meet or exceed the
requirements of ANSI A137.1. See product pages for series-specific technical data.
