Paints and varnishes - Determination of scratch resistance - Part 1: Constant-loading method (ISO 1518-1:2011)
ISO 1518-1:2011 specifies a test method for determining under defined conditions the resistance of a single coating or a multi-coat system of paint, varnish or related product to penetration by scratching with a scratch stylus loaded with a specified load. Penetration of the stylus is to the substrate, except in the case of a multi-coat system, in which case the stylus can penetrate either to the substrate or to an intermediate coat.
The method specified can be carried out
either as a "pass/fail" test, by testing with a single specified load applied to the stylus to assess compliance with a particular specification;
or by applying increasing loads to the stylus to determine the minimum load at which the coating is penetrated.
Beschichtungsstoffe - Bestimmung der Kratzbeständigkeit - Teil 1: Verfahren mit konstanter Last (ISO 1518-1:2011)
Dieser Teil von ISO 1518 legt ein Verfahren fest, mit dem unter definierten Bedingungen der Widerstand einer einzelnen Schicht oder eines Mehrschichtsystems aus Beschichtungsstoffen gegen das Eindringen eines mit einem festgelegten Gewichtstück belasteten Ritzstichels bestimmt wird. Der Ritzstichel dringt bis zum Substrat ein, außer bei Mehrschichtsystemen, bei denen der Ritzstichel entweder bis zum Substrat oder nur bis zu einer Zwischenschicht eindringt. Das festgelegte Verfahren kann durchgeführt werden a) entweder als „ja/nein“-Prüfung mit nur einer festgelegten Last auf dem Ritzstichel, um die Übereinstimmung mit einer bestimmten Spezifikation festzustellen; b) oder zur Bestimmung der Mindestlast (Einstufungsprüfung), unter der der Ritzstichel die Beschichtung bis zum Substrat durchdringt, wobei der Ritzstichel zunehmend belastet wird.
Peintures et vernis - Détermination de la résistance à la rayure - Partie 1: Méthode à charge constante (ISO 1518-1:2011)
L'ISO 1518-1:2011 spécifie une méthode d'essai pour la détermination, dans des conditions définies, de la résistance à la pénétration d'un revêtement monocouche ou d'un système multicouche de peinture, de vernis ou de produit assimilé, par rayure au moyen d'un stylet à rayer sur lequel est appliquée une charge spécifiée. La pénétration du stylet se fait jusqu'au subjectile, sauf dans le cas d'un système multicouche où le stylet peut pénétrer soit jusqu'au subjectile, soit jusqu'à une couche intermédiaire.
La méthode spécifiée peut être mise oeuvre
1. soit comme essai de conformité (conforme/non conforme), en appliquant une charge fixe spécifiée sur le stylet pour évaluer la conformité à une spécification particulière;
2. soit en appliquant des charges croissantes sur le stylet pour déterminer la charge minimale à laquelle il y a pénétration dans le revêtement.

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 2.
The main task of technical committees is to prepare International Standards. 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 document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 1518-1 was prepared by Technical Committee ISO/TC 35, Paints and varnishes, Subcommittee SC 9,
General test methods for paints and varnishes.
It cancels and replaces ISO 1518:1992, which has been technically revised. The main changes are:
a) the number of the standard has been changed from ISO 1518 to ISO 1518-1;
b) a principle clause has been added;
c) two versions of the test apparatus are now described;
d) the minimum length of the scratch has been reduced from 60 mm to 40 mm;
e) the magnification of the lens used to examine the scratch has been specified as at least ×4;
f) the supplementary test conditions (formerly Annex A) have been integrated in the test report;
g) a clause on precision has been added;
h) Annex B specifying a procedure for re-tipping scratch-test needles has been deleted.
ISO 1518 consists of the following parts, under the general title Paints and varnishes — Determination of
scratch resistance:
⎯ Part 1: Constant-loading method
⎯ Part 2: Variable-loading method

INTERNATIONAL STANDARD ISO 1518-1:2011(E)
Paints and varnishes — Determination of scratch resistance —
Part 1:
Constant-loading method
1 Scope
This part of ISO 1518 specifies a test method for determining under defined conditions the resistance of a
single coating or a multi-coat system of paint, varnish or related product to penetration by scratching with a
scratch stylus loaded with a specified load. Penetration of the stylus is to the substrate, except in the case of a
multi-coat system, in which case the stylus can penetrate either to the substrate or to an intermediate coat.
The method specified can be carried out
a) either as a “pass/fail” test, by testing with a single specified load applied to the stylus to assess
compliance with a particular specification;
b) or by applying increasing loads to the stylus to determine the minimum load at which the coating is
penetrated.

3 Principle
A scratch stylus loaded with a specified load is drawn over a coating at a constant speed. The following test
parameters are specified:
⎯ the geometry of the stylus tip;
⎯ the range within which the test load may lie and the increments by which it may be increased;
⎯ the procedure by which the stylus is lowered on to the coating;
⎯ the speed at which the stylus travels and the minimum length of the scratch.
ISO 1518-1:2011(E)
The scratch is examined to see if the coating has been penetrated to the extent specified for a single specified
test load (“pass/fail” test) or to determine the minimum test load required for penetration.
4 Apparatus
4.1 Scratch apparatus, two versions of which are illustrated in Figure 1 and Figure 2, with the following
characteristics:
⎯ The test load acting on the scratch stylus fixed to the load beam can be produced either by a weight
attached to the stylus (see Figure 1) or by a weight which slides along a graduated load beam
(see Figure 2).
⎯ The test load shall be 1 N to 20 N, shall be adjustable in increments of 0,5 N and shall be accurate to
within 0,2 N.
⎯ The test panel held in a panel holder is moved relative to the stylus by means of a linear actuator driven
by a motor. The speed at which the stylus travels shall be (35 ± 5) mm/s and the length of the scratch
shall be at least 40 mm. The length of the scratch can affect the result.
⎯ A lowering device with a flat ramp brings the stylus smoothly into contact with the coating at the beginning
of the movement of the panel holder. The angle of the ramp shall be (12,5 ± 2,5)°.
Some types of apparatus are designed so that the load beam moves and the test panel is fixed. Such types of
apparatus may also be used.
4.2 Scratch stylus A, having a hemispherical hard-metal tip of radius (0,50 ± 0,01) mm.
4.3 Scratch stylus B, having a hemispherical hard-metal tip of radius (0,25 ± 0,01) mm.
4.4 Scratch stylus C, having a hemispherical synthetic-ruby tip of radius (0,50 ± 0,01) mm.
4.5 Scratch stylus D, having a hemispherical synthetic-ruby tip of radius (0,25 ± 0,01) mm.
4.6 Indicating device, based on electrical contact between the stylus and the metallic substrate, to show
when the coating has been penetrated.
NOTE 1 This device is not suitable for paints containing electrically conducting pigments, for non-metallic substrates or
if penetration to an intermediate non-conducting coat is required.
NOTE 2 The indicating device can only be used when certain parts of the scratch apparatus are electrically insulated.
4.7 Magnifying lens, with at least ×4 magnification.
5 Sampling
Take a representative sample of the product to be tested (or of each product in the case of a multi-coat
system), as described in ISO 15528.
Examine and prepare each sample for testing, as described in ISO 1513.
