Added clarification for odor testing. Added column for changing the backing weight only. The face fiber and weight a
25、long with the backing composition will not change. Added line to identify that clip testing is also required by the D&R before the material can be approved. Added column for new denier in table 1 Identified testing required for trunk mat applications. For cold resistance clarified that testing is ne
26、eded in both AMD and WMD directions. Added sample size 100 mm x 100 for mildew, heat aging and resistance to heat Added DV/PV table 2. 2013 01 11 - Updated format - Added VIEQ requirement - Removed SAE method for odor - Updated Trap Tear method - Removed note in section 3.8.9 adhesion to carpet subs
27、trate limiting requirement to extruded or molded samples. - Changed mandrel from 6 mm to 15 mm in 3.8.10 - Added Cold Curl and Coefficient of Friction - Changed taber from graduated requirements back to 1 requirement to reflect actual performance - Removed reference to edge treatments, being replace
28、d by WSS-M8P24-A - Deleted fiber loss requirement. - Changed fiber deterioration from a visual requirement (tape pull) to taber. - Removed instrumented option for resistance to crocking - Updated testing table.
