    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

    A user of test method ASTM D4970 pointed out that modern Martindales are capable of performing two separate lissajous sizes. He asked that the standard have wording to clarify the correct size of lissajous for this standard. In addition to this members of the Pilling task group discussed fuzzing and clarification is required in how to assess fuzzing especially taking into account the level of fuzz on the base fabric.
