This document specifies four methods of test for textile floor coverings (with or without an underlay, see Clause 9) using the Lisson Tretrad machine.
-
test A: determination of mass loss of textile floor coverings, also used to assess fibre bind of synthetic pile carpets;
-
test B: determination of stair nosing appearance change of textile floor coverings;
-
test C: determination of fibre bind on synthetic loop pile carpets;
-
test D: determination of fibre bind (hairiness) on needled floor coverings and floor coverings without pile.
