On a scale of 1 to 5, this carpet receives a
on a Hexapod test, which evaluates appearance retention after simulated foot traffic.
Shaw's 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
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."
The face weight for this style is
Face weight is measured as per unit area of pile yarn
floor coverings according to ASTM (American Society for Testing Materials)
method D-5848. Due to several processes involved in manufacturing, such as shearing,
the actual finished weight may reflect a variance of up to 7%. The weight is determined
by compensating for the factor of commercial moisture regain, as defined in ASTM
D-1909. The ASTM measurements are accepted industry norms and the most accurate
means of determining face weight.
