PTV-rated tiles have been tested and rated for their slip resistance using a Pendulum Test Value (PTV) scale. The PTV rating is a critical factor in determining whether a tile is safe for use in areas prone to water or other slipping hazards, such as bathrooms, kitchens, or outdoor spaces.
Key Points about PTV Ratings:
- Pendulum Test Value (PTV): The rating is derived from the pendulum test, which simulates the action of a foot sliding over the surface of the tile. A pendulum with a rubber slider is swung across the tile surface, and the resistance to slipping is measured.
- PTV Scale:
- 0-24: High slip potential
- 25-35: Moderate slip potential
- 36+: Low slip potential (safe for most public areas)
- Wet vs. Dry Ratings: The PTV test is conducted under both wet and dry conditions because tiles may have different levels of grip depending on moisture. The wet condition rating is particularly crucial for areas where water may be present.
- Application:
- PTV 36+: Recommended for high-risk areas like showers, pool surroundings, or outdoor spaces exposed to rain.
- PTV 25-35: Suitable for moderately risky areas like kitchens or indoor entrances.
- PTV 0-24: Suitable for low-risk, dry areas like bedrooms or living rooms.
PTV ratings ensure that tiles meet specific safety standards, especially in commercial or public buildings where slip hazards are a concern.
