TB-80 GRAFFITI RESISTANCE OF VARIOUS TOILET PARTITION MATERIALS Last Updated: 01/21/2008 |

INDEPENDENT LABORATORY TESTING Three samples of different toilet partition materials [Powder-Coated Metal (Metal), High Density Polyethylene (HDPE), Polypropylene (Polyprop), Plastic Laminate (P-Lam), Solid Phenolic Core (Phenolic) and Solid Color Reinforced Composite (SCRC)] were sent to an independent laboratory for testing and evaluation to determine the relative graffiti resistance of these materials. The tests were performed in accordance with American Society for Testing and Material ASTM D 6578-00 “Standard Practice for Determination of Graffiti Resistance” Section 9, Graffiti Removal Procedure Using Manual Solvent Rubs. This procedure prepares samples of each material with marks from a minimum of five different staining agents and allows these to set for at least 24 hours. The standard evaluates a test specimen’s graffiti resistance by progressively cleaning the marks with more aggressive cleaning methods1 and determining the first method that completely cleans the test specimen. A full description of the test is available from ASTM. Bobrick selected this ASTM standard because, in our opinion, this standard provided an objective, repeatable, and comparable procedure with which to analyze the relative graffiti resistance properties and ease of cleaning different types of toilet partition materials. In the tests conducted, nine different marking agents were used.2 A comparison of the cleanability results can be used to evaluate the relative graffiti resistances of different toilet partition materials. A copy of the independent laboratory test results is available upon request. See attached Bulletin for test results
