CONSTRUCT2012 Education Sessions F01 - tile standard changes
www.greensquared.com
Expected to launch next week
DCOF AcuTest
In lieu of ASTM C 1028

Uses dynamic COF, and slightly soapy water. Highly repeatable.
0.42 DCOF will be the standard
(0.6 SCOF is about 0.38 DCOF)
This new standard was just formalized last week. All the TCNA mfr
members are comfortable with it. Non-dated eference to ANSI A137.1
will handle this as soon as ANSI updates:
"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."

This does not YET apply to stone. It is much more variable.
The DCOF for ramps might not be established for a few more years.
Does not sound like DOJ has weighed in on it yet. TCNA was going to go to Access Board next, but it was suggested that they go right to the DOJ too, since they were the ones who blew the last standard to bits.
Also, the new TCNA 2012 recommends inclusion of qualified labor
language. Lists several recognized programs.
