Standard: ASTM C650 – Standard Test Method for Resistance of Ceramic Tile to Chemical Substances

Certification Required: N/A

Scope: Per ASTM C650: "This test method covers a procedure for determining whether, and to what degree, ceramic tiles are affected by prolonged exposure to chemical substances that are commonly used in the household or for cleaning purposes as well as other more severe conditions."

Applicable Products: Ceramic tiles

Test Procedure: Test specimens are thoroughly dried in an oven and then allowed to cool to room temperature. 20mL of each test solution is added to test tubes and the tile is placed on top. The assembly is then inverted so that the test tube rests on top of the tile. The assembly is left undisturbed for 24 hours and then the test tubes are removed. Each tile is thoroughly rinsed under running water for 10 minutes to remove residual solution, followed by oven drying and cooling to room temperature. The tile specimens are then visually examined for differences in appearance. Any samples that pass the visual inspection then have several lines drawn on them with a HB grade pencil, and the pencil marks are wiped with a damp cloth. If the pencil lines are removed from the treated surface, then the tile specimen is "not affected".

End Result: This test results in a determination of either "affected" or "not affected" for both the visual inspection and pencil tests.
