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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3.
Draft International Standards adopted by the technical committees are circulated to the member bodies for voting.
Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this part of ISO 12945 may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights.
International Standard ISO 12945-1 was prepared by Technical Committee ISO/TC 38, Textiles, Subcommittee
SC 24, Conditioning atmospheres and physical tests for textile fabrics.
ISO 12945 consists of the following parts, under the general title Textiles — Determination of fabric propensity to
surface fuzzing and to pilling:
� Part 1: Pilling box method
� Part 2: Modified Martindale method
� Part 3: Determination using a random tumble method
Annex A of this part of ISO 12945 is for information only.
ISO 12945-1:2000(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 in which 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 fuzzing and pilling propensity
as is likely to occur in end-use wear.
Particular attention is drawn to annex A which gives advice on the maintenance of the apparatus. It is
recommended that annex A be studied prior to carrying out the procedure.

INTERNATIONAL STANDARD ISO 12945-1:2000(E)
Textiles — Determination of fabric propensity to surface fuzzing
and to pilling —
Part 1:
Pilling box method
1 Scope
This part of ISO 12945 describes a method for the determination of the resistance to pilling and surface change of
textile fabrics.
2 Normative reference
The following normative document contains provisions which, through reference in this text, constitute provisions of
this part of ISO 12945. For dated references, subsequent amendments to, or revisions of, any of these publications
do not apply. However, parties to agreements based on this part of ISO 12945 are encouraged to investigate the
possibility of applying the most recent edition of the normative document indicated below. For undated references,
the latest edition of the normative document referred to applies. Members of ISO and IEC maintain registers of
currently valid International Standards.
ISO 139, Textiles — Standard atmospheres for conditioning and testing.
3 Terms and definitions
For the purposes of this part of ISO 12945, the following terms and definitions apply.
3.1
fuzzing
roughing up of the surface fibres and/or teasing out of the fibres from the fabric producing a visible surface change
NOTE This change can occur during washing, dry cleaning and/or wearing.
3.2
pills
entangling of fibres into balls (pills) that stand proud of the fabric and are of such density that light will not penetrate
and will cast a shadow
NOTE This change can occur during washing, dry cleaning and/or wearing.
3.3
pilling
generation of pills over the surface of the fabric
ISO 12945-1:2000(E)
4Principle
Specimens are mounted on polyurethane tubes and tumbled randomly in a cork-lined box at a constant rotational
speed. Fuzzing and pilling is assessed visually after a defined period of tumbling. Any special treatment of the
laboratory sample, i.e. washing, cleaning, has to be agreed upon and shall be stated in the test report.
5 Apparatus
5.1 Pill testing box, cubic, with internal dimensions, before lining, of 235 mm. All internal surfaces of the box
shall be lined with cork jointing material of 3,2 mm thickness. The box shall be rotated at (60� 2) r/min about a
horizontal axis passing through the centres of two opposite faces. One side of the box shall be removable for
access.
NOTE Advice on the calibration and comparison of pill testing boxes is given in annex A.
Cork linings shall be inspected at regular intervals and shall be replaced when obviously damaged or soiled in such
a way as to alter their frictional properties (see A.4).
5.2 Polyurethane specimen tubes, (four are required), each measuring (140� 1) mm in length by
(31,5� 1) mm outside diameter by (3,2� 0,5) mm wall thickness, mass (52,25� 1) g.
5.3 Mounting jig, used to mount specimens on the tubes.
5.4 Self-adhesive polyvinyl chloride (PVC) tape, 19 mm wide.
5.5 Sewing machine.
5.6 Viewing cabinet, illuminated by a white fluorescent tube or bulb (the colour temperature of the light source
is not critical) to give uniform illumination over the width of the specimen(s) and masked in such a way that the
observer does not look directly into the light. Position the illuminant at an angle between 5° and 15° to the plane of
the specimen (see Figure 1). The distance between the eye and the specimen shall be between 30 cm and 50 cm
for normal corrected vision.
