6.2. Pile Height: Insert a metal rule, graduated in 0.100 inch, between and parallel to the lengthwise pile rows and measure the height of the pile in five areas at least two inches apart. The average of the measurements shall be reported as the pile height. Determine compliance with Table 1.

6.3. Pile Height Differential: Insert a metal rule, graduated in 0.100 inch, between and parallel to the lengthwise pile rows and measure the height of the high and low pile, respectively, in five areas at least two inches apart. Average the five readings taken from the low pile and then separately average the five readings taken from the high pile. The difference between the average height of the high pile and the average height of the low pile shall be the pile height differential. Applies to Multilevel carpet only.
