In November 2007, the Ceramic Tile Distributors Association (CTDA) and the Tile Council of North America (TCNA) launched the Porcelain Tile Certification Agency (PTCA) to certify porcelain tile.
Porcelain tile is defined as an impervious tile with a water absorption of 0.5% or less as measured by the ASTM C373 test method. There are, however, many instances in which tile not meeting this standard is advertised and sold as porcelain tile. Marketplace confusion, installation problems and even liability concerns can result when non-porcelain tile is misrepresented in the marketplace.
Under the PTCA certification program, manufacturers who want to prove that their tile is porcelain -- meeting the 0.5% water absorption criteria -- can have their product tested to determine compliance with that requirement. They may then use the PTCA certification mark on their product packaging, marketing materials, etc., as confirmation of that compliance.
The program is designed to benefit manufacturers, distributors and end users who are all impacted by the misrepresentation of non-porcelain tile. Marketplace confusion currently exists over what is and is not porcelain. Porcelain certification will verify that the samples tested all met the water absorption criteria.
Manufacturers may apply for certification by submitting samples of the lightest color in each series for qualifying tests and by paying for the testing as well as the initial and annual certification and participation fees.
The PTCA will conduct the porcelain certification program, educate the public on the benefits of porcelain certification, conduct research activities, and assist in the development of tests or test methods for porcelain tile.
