P.E.I.GUIDE

PEI (ISO 10545-7)Testing is performed to measure the effect abrasion may have on functional characteristics of a glazed surface i.e. chemical, stain resistance, and ease of cleaning. The following is a list of P.E.I. ratings for a tile’s suitability to various applications: ISO (P.E.I.) Classifications

Class 0. Suitable for walls only.

Class 1. Recommended for wall use. May be used on bath floors without direct access to outdoor elements.

Class 2. Suitable for residential floors. For interior use where abrasive foot traffic is minimal-such as bathrooms or bedrooms.

PEI (ISO 10545-7) Testing is performed to measure the effect abrasion may have on functional characteristics of a glazed surface i.e. chemical, stain resistance, and ease of cleaning. The following is a list of P.E.I. ratings for a tile’s suitability to various applications: ISO (P.E.I.) Classifications

Class 3. Ideal for most residential floors. Subject to normal foot traffic and usage (including kitchens, outdoor entryways and hallways).

Class 4. Great for all residential interiors. Suitable for light to medium commercial applications. Will withstand moderate foot traffic in many commercial areas (commercial kitchens, hotel rooms, exhibition halls, etc.).

Class 5.Great for all residential interiors. Also ideally suited for most commercial applications under normal foot traffic conditions (shopping centers, hotel foyers, walkways, and industrial applications).

Please note:Through-body porcelain tiles (unglazed) are not classified according to these P.E.I. test procedures.

SHADE GUIDE

V1 = Uniform appearance: Differences among pieces from the same production run are minimal.

V2 = Slight variation: Clearly distinguishable differences in texture and/ or pattern within similar colors.

V3 = Moderate variation: While the colors present on a single piece of tile will be indicative of the colors to be expected on the other tiles, the amount of colors on each piece may vary significantly. For example “that little bit of color” on one piece of tile may be the primary color on the next piece.

V4 = Random variation: Random color differences from tile to tile, so that one tile may have totally different colors from that on other tiles. Thus, the final installations will be unique.

OFFSET JOINTS

As per the ANSI specifications 4.3.8.2 Running Bond/Brick Joint Offset Recommendations

For running bond/brick joint patterns utilizing tiles (square or rectangular) where the side being offset is greater than 18" (nominal dimension), the running bond offset will be a maximum of 33% otherwise specified by the tile manufacturer. If an offset greater than 33% is specified, specifier and owner must approve mock-up the side being offset is greater than 18" (nominal dimension), the running and lippage. In addition, Tile Mode recommends a maximum of 25% offset for Tiles 36" or longer.

MOHS GUIDE

The MOHS' test uses 10 reference minerals to scratch the surface of a tile. The MOHS' Scale is based on a relative value of 1-10; with 1 being the softest and 10 being the hardest. The MOHS' test is used as a general indicator of the scratch resistance of a glazed tile, not an absolute standard or measurement of abrasion resistance. Please reference the following chart for MOHS ratings:

Comparison Mineral
1. Talc Sheet Vinyl (inexpensive type)
2. Selenite Wood Floor same hardness as fingernail
3.Calcite Laminate Floor hardness of a penny
4.Fluorite Black Marble (not recommended for floors)
5. Apatite Ceramic Tile(min) a knife blade
6. Microline Glazed ceramic tile or window glass
7.Quartz Glazed ceramic tile (range 5min-8max)
8.Topaz Granite,unglazed porcelain
9.Corundum Unglazed porcelain (range 6min-9max)
10. Diamond Diamond- no flooring this hard-yet!

This chart does not encompass every possible product. Test is for comparison purposes only:

not intended as an absolute standard or scientific measurement.

Please note: Glazed floor tile should have a minimum MOHS rating of 5.

C.O.F. GUIDE

C.O.F. is an acronym Coefficient of Friction and a term used to determine the slip resistance of a tile. The C.O.F. is not a typical consideration for most residential settings. If homeowners are concerned about slip-falls, you’ll want to be aware of which tiles have higher slip-resistant ratings. The A.D.A, Americans with Disabilities Act, recommends a wet static C.O.F. of 0.6 or greater for accessible routes and 0.8 for ramps in areas of public use. There is a “new” dynamic coefficient of friction, D.C.O.F., being used to determine slip resistance. The D.C.O.F. rating to determine slip resistance for accessible routes in areas of public use is 0.42 or greater. If slip resistance is a factor, we suggest following the A.D.A recommendation.
