Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www .iso .org/ patents).

in accordance with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement).
This second edition cancels and replaces the first edition (ISO 12945-2:2000), which has been
technically revised.
The main changes compared to the previous edition are as follows:
— in Clause 9, visual assessment of pilling, fuzzing, and matting has been carried out according to
ISO 12945-4.

ISO 12945-2:2020(E)
Introduction
Pills are formed when fibres on a fabric surface “tease out” and become entangled during wear. Such
surface deterioration is generally undesirable, but the degree of consumer tolerance for a given level of
pilling will depend on the garment type and fabric end-use.
Generally, the level of pilling which develops is determined by the rates of the following parallel
processes:
a) fibre entanglement leading to pill formation;
b) development of more surface fibre;
c) fibre and pill wear-off.
The rates of these processes depend on the fibre, yarn and fabric properties. Examples of extreme
situations are found in fabrics containing strong fibres versus fabric containing weak fibres. A
consequence of the strong fibre is a rate of pill formation that exceeds the rate of wear-off. This results
in an increase of pilling with an increase of wear. With a weak fibre the rate of pill formation competes
with the rate of wear-off. This would result in a fluctuation of pilling with an increase of wear. There are
other constructions that the surface fibre wear-off occurs before pill formation. Each of these examples
demonstrates the complexity of evaluating the surface change on different types of fabric.
The ideal laboratory test would accelerate the wear processes a), b) and c) by exactly the same factor
and would be universally applicable to all fibre, yarn and fabric types. No such test has been developed.
However, a test procedure has been established in which fabrics can be ranked in the same order of
pilling, fuzzing, and matting propensity as is likely to occur in end-use wear.
The modification to the very widely adopted Martindale abrasion testing machine on which this
document is based is described in Reference [8].
