DCOF AcuTestsm: The New Method for Measuring Coefficient of Friction on Tile

Tile Council of North America (TCNA), is pleased to announce there will soon be a new standard for coefficient of friction (COF) testing on tile.

The DCOF AcuTest method will soon replace ASTM C1028 as the specified method for COF testing.  DCOF AcuTest is a more repeatable and reproducible method that gives a better indication of actual slip potential on a tile surface.

This new method uses the BOT 3000 automated portable testing device with a specific type of rubber sensor and slightly soapy water.  The sensor is resurfaced using a sanding device designed by the TCNA’s Product Performance Testing Laboratory.

A new version of ANSI A137.1 Specifications for Ceramic Tile will soon be published with the new DCOF AcuTest method.  Additionally, for the first time there will be a minimum COF requirement of 0.42 for level interior tile surfaces expected to be walked upon when wet.

The new A137.1 will also include a two-page informational section (section, which will help specifiers better understand how to choose the right tile for every application.

TCNA’s lab is fully-equipped to test all tile products to this new and improved coefficient of friction test method.  For more information on this and other tile and tile-related product testing, visit www.tileusa.com/test_main.htm or contact TCNA at 864-646-8453.

World’s First Glass Tile Standard Now Available

Tile Council of North America (TCNA) is pleased to announce the availability of the world’s first standard for glass tile, ANSI A137.2 American National Standard Specifications for Glass Tile.

Since glass tiles have performance and aesthetic properties very different from ceramic tiles, a separate and unique standard was required.  ANSI A137.2 categorizes and defines types of glass tiles and establishes aesthetic and performance standards within each category.

Some of the key issues the standard covers include:

  • Methods of manufacture: cast, fused, and low temperature-coated
  • Categorization by size: large format, mosaic, and miniature mosaic
  • What constitutes a defect
  • Mounting criteria for mounted glass mosaics
  • Measurement and definition of translucence
  • Strength criteria
  • Thermal shock resistance using real life temperature ranges
  • Levels of recycled content

With standard criteria in place, the industry now has a consensus baseline for manufacturing quality and a valuable tool which can aid in the development of new installation standards and in the general specification of glass tile.

“With the wide variety of products available around the world, this much-needed standard aims to reduce confusion in the marketplace,” stated TCNA Executive Director, Eric Astrachan.  “TCNA and its members are confident that the clear and consistent definitions and standards established by ANSI A137.2 will help preserve the value, popularity, and quality associated with glass tiles today.”

Print and electronic copies of ANSI A137.2 can be purchased from TCNA.  To order this standard contact TCNA at [email protected]  or (864) 646-8453.

2013 TCNA Handbook call for submissions: January 13, 2012 deadline

The Tile Council of North America is asking the industry to submit new tile installation guidelines or edits to existing guidelines for consideration by the Handbook Committee. The deadline for submissions is January 13, 2012.

The Handbook Conference will be held June 19-20, 2012, in downtown Atlanta.

Submission criteria and format includes:

  • All submissions must be specific, i.e., exact language must be provided.
  • Each submission must be accompanied by a Handbook submission form.
  • For new methods, include a generic drawing.
  • Edits to the existing Handbook must include a page clearly showing where the requested changes are to be made.
  • New methods should be submitted in a form that is ready to be inserted into the Handbook (see submission form for new details).
  • It is recommended you have the latest version of the Handbook and American National Standards A108/A118/A136.1 to reference when drafting your submissions.
  • Please compare your submission to an existing method to make sure all necessary fields are listed. All testing and supporting documentation should be included (visit website below for sample).
  • Submissions that do not meet the Handbook format and criteria requirements will be returned.

Contractors and tile installers are encouraged to make submissions via their organizations or associations. All others should contact Stephanie Samulski at 1-313-999-9714, or visit the TCNA Handbook submission website at http://www.tileusa.com/.
