| Primary floor application | Specify a product tested to ANSI A326.3 with a wet DCOF of ≥ 0.42 for level interior floors expected to be walked upon when wet. | Provides a measurable slip-resistance performance criterion for wet, level walking surfaces. | Request the current test report and confirm the tested finish, color, texture, and lot are the same as the proposed tile. |
| Tile location | Use floor-rated decorative tile on level floors; use wall-only art tile on vertical surfaces unless floor suitability is specifically documented. | Decorative appearance does not establish suitability for pedestrian traffic, wet exposure, or abrasion. | Review the technical data sheet, intended-use statement, and installation instructions. |
| Surface texture | Prefer a stable, uniform texture that supports the required wet DCOF without sharp projections or excessive surface irregularity. | Raised decoration, deep relief, or uneven edges can affect cleaning, drainage, foot contact, and accessibility. | Review a full-size sample and inspect the installed mock-up under dry and wet conditions. |
| Tile size and joint layout | Coordinate tile module, grout joint, and pattern repeat with the floor plan; avoid creating abrupt height changes at transitions. | Small-format patterns may improve conformity to contours, while poor alignment or lippage can create trip hazards. | Confirm allowable lippage, joint width, movement joints, and transitions with the applicable local code and tile standard. |
| Water absorption | Select the absorption classification required by the project environment; porcelain tile is commonly defined as having water absorption of 0.5% or less under applicable ceramic tile classification standards. | Lower absorption can support moisture resistance, but it does not replace wet-slip testing or proper installation. | Check the manufacturer’s absorption test result and the project specification before approval. |
| Abrasion and traffic | Match the tile’s documented abrasion or usage classification to the expected pedestrian traffic, cleaning frequency, and wheeled loads. | Glazes, printed motifs, and relief details may wear differently in entrances, hospitality areas, retail spaces, and public corridors. | Evaluate a sample against the project’s traffic category and maintenance equipment. |
| Wet-area exposure | For entrances, wash areas, pool surrounds, kitchens, and other locations likely to become wet, require documented wet performance and a suitable drainage design. | Slip risk depends on water, contaminants, footwear, slope, cleaning, and maintenance—not on tile appearance alone. | Coordinate tile selection with slope, drainage, entrance matting, cleaning procedures, and local regulations. |
| Color and pattern contrast | Use decorative contrast to support wayfinding and zoning without creating visual confusion or disguising changes in level. | Strong patterns can affect perceived depth, edge visibility, and navigation for users with reduced vision. | Review the pattern at the intended scale, lighting level, viewing distance, and accessibility conditions. |
| Cleaning and maintenance | Specify compatible detergents, grout, sealers, and cleaning equipment; avoid residues that can reduce surface traction. | Oil, soap, dust, polish, and unsuitable coatings can change in-service slip performance. | Obtain a written maintenance schedule and test cleaning products on an approved mock-up. |
| Global project compliance | Use ANSI A326.3 as the specified test method where applicable, then confirm local building, accessibility, fire, hygiene, and wet-area requirements. | Regulatory requirements vary by country, building type, exposure, and installation condition. | Have the project architect, code consultant, and qualified tile installer review the final specification. |
| Approval documentation | Approve only after reviewing the product data sheet, ANSI A326.3 wet DCOF report, absorption data, installation method, grout specification, and maintenance plan. | A complete submittal links laboratory performance with the exact product and the actual installed conditions. | Retain approved samples, test reports, batch information, and installation records for project closeout. |
