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.
International Standard ISO 12947-3 was prepared by Technical Committee ISO/TC 38, Textiles.
ISO 12947 consists of the following parts under the general title Textiles — Determination of the abrasion resistance
of fabrics by the Martindale 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 ISO 12947.

Part 3:
Determination of mass loss
1 Scope
This part of ISO 12947 is applicable to the determination of the mass loss 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 ISO 12947-1.

For the purposes of this part of ISO 12947 the definitions given in ISO 12947-1 and ISO 12947-2 apply.
4 Principle
A circular specimen is 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

ISO 12947-3:1998(E)
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 mass loss of the test specimens.
The specimens are mounted in the specimen holders with foam backing. Specimens with a mass per unit area
greater than 500 g�m are mounted in the specimen holders without foam. Pile fabrics and cord fabrics which are
tested without foam backing are subjected to a specified preparatory treatment (see 7.5.2).
Two abrasion 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:
a) (795 – 7) g for workwear, upholstery, bed linen and fabrics for technical use (nominal pressure of 12 kPa);
b) (595 – 7) g for apparel and household textiles, excluding upholstery and bed linen (nominal pressure of 9 kPa).
The mass loss of the test specimen is determined for each of the established numbers of rubs according to the
number of rubs at which specimen breakdown occurs (see table 1).

5 Apparatus and materials
In addition to the test apparatus and auxiliary materials specified in ISO 12947-1, a balance, having an accuracy of
1 mg, is required.
6 Conditioning and testing atmosphere
The standard temperate atmosphere for conditioning and testing textiles as defined in ISO 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 ISO 2859-1).
Ensure throughout sampling and specimen preparation that handling imposes the minimum possible tensile stress
so as to prevent incorrect extension of the textile fabric.

ISO 12947-3:1998(E)
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 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 ensu
