Paints and varnishes - Determination of scratch resistance - Part 1: Constant-loading method (ISO 1518-1:2023)
This document 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. The stylus penetrates 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 conformity with a particular specification; or
b) as an assessment test by applying increasing loads to the stylus to determine the minimum load at which the coating is penetrated.
NOTE Neither this document nor ISO 1518-2 specifies a method using a curved stylus, which is specified in ISO 12137. The choice between the three methods depends on the particular practical problem.

Peintures et vernis - Détermination de la résistance à la rayure - Partie 1: Méthode à charge constante (ISO 1518-1:2023)
Le présent document 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. Le stylet pénètre 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 en œuvre:
a) comme essai de conformité («conforme/non conforme»), en appliquant une charge fixe spécifiée sur le stylet pour évaluer la conformité à une spécification particulière; ou
b) comme essai d’évaluation, en appliquant des charges croissantes sur le stylet pour déterminer la charge minimale à laquelle il y a pénétration dans le revêtement.
NOTE Ni le présent document ni l’ISO 1518‑2 ne spécifient de méthode utilisant un stylet arrondi, celle-ci étant spécifiée dans l’ISO 12137. Le choix entre les trois méthodes dépend du problème pratique particulier.

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).Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO's adherence to
the World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see
www.iso.org/iso/foreword.html.This document was prepared by Technical Committee ISO/TC 35, Paints and varnishes, Subcommittee
SC 9, General test methods for paints and varnishes.This third edition cancels and replaces the second edition (ISO 1518-1:2019), which has been technically
revised.The main changes are as follows:
— Since the same styli have different designations in the ISO 1518-1:2011 and ISO 1518-1:2019 editions,
it now was agreed to create a total new designation considering the type of the stylus already in
the designation. HM represents the hard-metal tip and SR represents the synthetic-ruby tip. The
number stands for the diameter of the tip.— Annex A giving a comparison of the designation of the scratch styli in the different editions of
ISO 1518-1 has been added.— The text has been editorially revised and the normative references have been updated.
A list of all parts in the ISO 1518 series can be found on the ISO website.Any feedback or questions on this document should be directed to the user’s national standards body. A

4 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 can lie and the increments by which it can be increased;
— the procedure by which...
