Dear Mr. DiPilla:

Thank you for the January 29, 2004 Status Report from Task Group F13.10.01 on Generic Methodologies

for Quantifying Walkway Slip Resistance Measurements. This report was reviewed by COS at their

recent meeting.

As you know, COS has had concerns with the lack of precision and bias, and the reference to proprietary

apparatus, in standards F1677, F1678, F1679, and D5859. Due to their proprietary nature, COS has ruled

Additionally, the lack of a precision and bias statement in these methods violates required ASTM Form

and Style.

COS is pleased to hear that Committee F13, through task group F13.10.01, is working towards the

development of methods that are not apparatus-specific, and expects that these standards will be

developed by September 30, 2006. At that time, COS intends to withdraw the four existing F13 methods

mentioned above if Committee F13 has not completed action. Finally, COS would like to receive a report

prior to each of their future meetings detailing the progress of F13.10.01; the first update is thus requested

by August 15, 2004. This issue will be monitored and may be revisited based upon progress displayed by

F13.

COS looks forward to receiving this information. If you have any questions, please do not hesitate to

Sincerely,

William H. Childs

Chairman, COS
