ASTM WK46444

    Revision of D4970 / D4970M - 10e1 Standard Test Method for Pilling Resistance and Other Related Surface Changes of Textile Fabrics: Martindale Tester

    (What is a Work Item?)

    Active Standard: D4970 / D4970M - 10e1

    Developed by Subcommittee: D13.60 | Committee D13 | Contact Staff Manager


    1. Rationale

    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.
