The pilling task group discussed the difficulty in grading when performing ASTM D4970. The problem is caused by such a small sample size. A larger sample area is possible with the Martindale and the group suggested that a separate option for a large sample area be included. This should resolve issues with grading and incorporate the benefits for fabrics which fuzz or have large widely spaced pills.
