More than four years of cross-disciplinary industry collaboration and 4,000-plus hours of research from the TCNA
Laboratory Services team have culminated in today’s announcement of two new standards: ANSI A137.3, the American National Standard Specifications for Gauged Porcelain Tiles and Gauged Porcelain Tile Panels/Slabs, and its companion, ANSI A108.19, Interior Installation of Gauged Porcelain Tiles and Gauged Porcelain Tile Panels/Slabs by the Thin-Bed Method bonded with Modified Dry-Set Cement Mortar or Improved Modified Dry-Set Cement Mortar.
Currently known in industry parlance as the “thin tile” standards, the standards use the term “gauged” to cover a range of precise thicknesses that can carry different loads and be used in different ways, taking a similar approach to standardized wire gauges and gauged sheet metal. Two classes of gauged tile products are defined—- those for wall applications from 3.5 to 4.9 mm and for floor and wall applications from 5.0 to 6.5 mm.
ANSI A137.3 standardizes the minimum required properties for the products themselves and ANSI A108.19 standardizes the methodologies for installing the products in interior installations by the thin-bed method with specific mortars.
These standards, developed for the benefit of all tile consumers, are the result of a multi-year consensus process of the ANSI Accredited A108 Standards Committee, which maintains a broad and diverse group of participants reflecting stakeholder interests in all aspects of the tile industry.
“Interest in gauged tiles has been growing exponentially the last few years,” says Eric Astrachan, Executive Director, Tile Council of North America, which serves as Secretariat of the Committee. “Such growth encourages more products to enter the marketplace, but without standards tile consumers would have no way to know what to expect in terms of performance. Installers especially were asking for standards to allow for installation practices to be developed based on consistent tile properties.
Without such, it was feared that problems resulting from an undefined range of products could have hindered growth of this exciting market segment. We are very pleased to announce these standards today and congratulate and thank the many across our industry that worked for years on their development. We hope these standards, the first of their kind in the world, will help lead the way forward to international gauged tile standards.”
A free download of a preview copy is available from TCNA beginning today, and a professional publication of both standards will be available for purchase from TCNA in July.
As the voice of the U.S. standards and conformity assessment system, the American National Standards Institute (ANSI) empowers its members and constituents to strengthen the U.S. marketplace position in the global economy while helping to assure the safety and health of consumers and the protection of the environment.
The Institute oversees the creation, promulgation and use of thousands of norms and guidelines that directly impact businesses in nearly every sector: from acoustical devices to construction equipment, from dairy and livestock production to energy distribution, and many more. ANSI is also actively engaged in accreditation – assessing the competence of organizations determining conformance to standards.
TCNA is a trade association representing manufacturers of ceramic tile, tile installation materials, tile equipment, raw materials, and other tile-related products. Established in 1945 as the Tile Council of America (TCA), it became TCNA in 2003, reflecting its membership expansion to encompass all of North America.
Tile Council is recognized for its leadership role in facilitating the development of North American and international industry quality standards to benefit tile consumers. Additionally, TCNA regularly conducts independent research and product testing, works with regulatory, trade, and other government agencies, offers professional training, and publishes industry-consensus guidelines and standards, economic reports, and promotional literature.
