Specification

Chemical Resistance, ASTM C650-04
Chemical resistance is measured using ASTM C650-04. A tile sample is placed in continuous contact with
a variety of chemicals for 24 hours, rinsing the surface and then examining the surface for visible
variation.
COLOR SHADE VARIATIONS
The color shade or shades of all tile varies some degree from piece to piece, from each production run
to run. At least several pieces from the same production run should be reviewed whenever possible to
determine acceptable color shade variations. Any questions or concerns about your tile selection should
be clarified prior to installation.
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 tile. Thus, the final installation will be unique.
