This document specifies four methods of test for textile floor coverings (with or without an underlay, see Clause 9<\/span>) using the Lisson Tretrad machine.<\/p>\n

    \n
  1. \n

    test A: determination of mass loss of textile floor coverings, also used to assess fibre bind of synthetic pile carpets;<\/p>\n<\/li>\n

  2. \n

    test B: determination of stair nosing appearance change of textile floor coverings;<\/p>\n<\/li>\n

  3. \n

    test C: determination of fibre bind on synthetic loop pile carpets;<\/p>\n<\/li>\n

  4. \n

    test D: determination of fibre bind (hairiness) on needled floor coverings and floor coverings without pile.<\/p>\n<\/li>\n<\/ol>\n
