On a scale of 1
to 5, this carpet receives a 3.5 on a Hexapod test, which
evaluates appearance retention after simulated foot traffic.
The performance rating is based on
an international test method known
as Hexapod. This procedure evaluates
appearance retention of carpet.
The instrument used to test the
carpet is composed of a circular
rotating drum with carpet placed on
the inside. Also placed inside the
drum is an eight-pound steel ball
with six pods. As the drum rotates,
the ball falls on the carpet face,
simulating footsteps.
After the standard number of
rotations, carpets are then assessed
using the Carpet and Rug Institute (CRI)
performance rating scale. The lowest
rating of 1 means "severe change in
appearance" and the highest rating
of 5 means "no change in
appearance."
