Foreword
IS0 (the International Organization for Standardization) is a worldwide federation of national standards bodies (IS0
member bodies). The work of preparing International Standards is normally carried out through IS0 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. IS0 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.
International Standard IS0 12947-2 was prepared by Technical Committee ISOTTC 38, Textiles.
IS0 12947 consists of the following parts under the general title Textiles - Determination of the abrasion resistance
of fabrics by the Map?indale method:
- Part 1: Martindale abrasion testing apparatus
- Part 2: Determination of specimen breakdown
- Part 3: Determination of mass loss
- Part 4: Assessment of appearance change
Annex A forms an integral part of this part of IS0 12947. Annex B is for information only.

INTERNATIONAL STANDARD o IS0
Textiles - Determination of the abrasion resistance of fabrics
by the Martindale method -
Part 2:
Determination of specimen breakdown
1 Scope
This part of IS0 12947 is applicable to the determination of the inspection interval to breakdown of specimens
covering all textile fabrics including nonwovens apart from fabrics where the specifier indicates the end performance
as having a low abrasion wear life.
NOTE Further introductory comments are given in Part 1 of this international Standard.

3.2
specimen breakdown
breakdown point which is reached:
in woven fabrics, when two separate threads are completely broken;
- in knitted fabrics, when one thread is broken causing a hole to appear;
in pile fabrics, when the pile is fully worn off;
in nonwovens, when the first hole resulting from the wear is of a diameter at least equal to 05 mm.
4 Principle
A circular specimen, mounted in a specimen holder and subjected to a defined load, is rubbed against an abrasive
medium (standard fabric) in a translational movement tracing a Lissajous figure, the specimen holder being
additionally freely rotatable around its own axis perpendicular to the plane of the specimen. The evaluation of the
abrasion resistance of the textile fabric is determined from the inspection interval to breakdown of the specimens.
The specimens are mounted in specimen holders with foam backing. Specimens with a mass per unit area greater
500 g-m-* are mounted in specimen holders without foam. Pile fabrics and cord fabrics which are tested
than
without foam backing are subjected to a specified preparatory treatment (see 7.5.2).
Two abrasion load parameters are specified. The total effective mass of the abrasion load (i.e. the mass of the
specimen holder assembly and the appropriate loading piece) are:
(795 t 7) g for workwear, upholstery, bed linen and fabrics for technical use (nominal pressure of 12 kPa);
a)
b) (595 rt 7) g for apparel and household textiles, excluding upholstery and bed linen (nominal pressure of 9 kPa).
Abrasion testing is continued up to breakdown (see clause 8) of the test specimen.
The inspection interval is determined by the specimen breakdown. The number of rubs is recorded at which
specimen breakdown is not yet observed (this number of rubs is the upper limit of the time elapsed before specimen
breakdown and at the same time the lower limit of the abrasion interval at which specimen breakdown occurs).
5 Apparatus and materials
5.1 Test apparatus and auxiliary materials, as specified in IS0 12947-1.
5.2 Magnifying glass or microscope, e.g. 8 x magnification.
6 Conditioning and testing atmosphere
The standard temperate atmosphere for conditioning and testing textiles as defined in IS0 139 shall be used,
i.e. a temperature of (20 + 2) “C and a relative humidity of (65 + 5) %.
7 Sampling and preparation of test specimens
7.1 General
Perform sampling in accordance with statistical rules (see IS0 2859-l).
Ensure throughout sampling and specimen preparation that handling imposes the minimum possible tensile stress
so as to prevent incorrect extension of the textile fabric.

7.2 Selection of the laboratory sample
Select the laboratory sample from a test lot to be representative of properties of the textile fabric. Check the
representative nature of sampling from the start or end of a textile fabric.
Take the laboratory sample from across the full fabric width.
7.3 Sampling of the test specimens from the laboratory sample
Before sampling the test specimens from the laboratory samples, condition the laboratory samples, free from
tension, for at least 18 h on a smooth horizontal surface with free access of air exposed to the standard atmosphere
specified in clause 6.
Take the test specimens at least 100 mm from the edge distributed across the entire laboratory sample. Take a
sufficient number of test specimens (at least three) to be in accordance with statistical rules (see 7.1).
For woven fabrics, take the specimens so that they each contain different warp and weft threads.
For patterned fabrics or fabrics with textured surface, take care to ensure that the test specimens contain all
characteristic parts of the pattern, ensuring that the parts of the pattern likely to be sensitive to abrasion are
contained in the test specimens.
7.4 Dimensions of specimens and auxiliary materials
7.4.1 Dimensions of the test specimens
The diameter of the test specimens shall be 38+od5 mm.
7.4.2 Dimensions of abradant
The dimensions of the abradant shall be at least 140 mm in diameter or length and width.
7.4.3 Dimensions of the abradant felt substrate
The diameter of the woven wool felt underlay shall be 140 +od5 mm.
7.4.4 Dimensions of the specimen holder foam backing
The diameter of the specimen holder foam backing shall be 38+od5 mm.
7.5 Specimen preparation for specific fabrics
7.51 Stretch fabrics
See annex A, clause A.1 .
7.5.2 Cord fabrics and pile fabrics
See annex A, clause A.2.
7.6 Preparation and mounting of the test specimens and cutting-out and mounting
of the auxiliary materials
7.6.1 Preparation
Stamp or cut out the test specimens from the laboratory sample. Give particular attention to the clean status of the
cut edges to prevent the occurrence of unwanted material loss in subsequent handling.
