Paints and varnishes - Determination of scratch resistance - Part 1: Constant-loading method (ISO 1518-1:2019)

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. 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
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 will depend on the particular practical problem.

Beschichtungsstoffe - Bestimmung der Kratzbeständigkeit - Teil 1: Verfahren mit konstanter Last (ISO 1518-1:2019)

Dieses Dokument 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 Sub¬strat 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 Überein-stimmung mit einer bestimmten Spezifikation festzustellen; oder
b)   als Einstufungsprüfung durch Bestimmung der Mindestlast, unter der der Ritzstichel die Beschichtung bis zum Substrat durchdringt, wobei der Ritzstichel zunehmend belastet wird.
ANMERKUNG   Weder dieses Dokument noch ISO 1518 2 legt ein Verfahren unter Verwendung eines bogenförmigen Stichels fest, wie es in ISO 12137 angegeben wird. Die Wahl eines der drei Verfahren hängt von der jeweiligen konkreten Aufgabenstellung ab.

Peintures et vernis - Détermination de la résistance à la rayure - Partie 1: Méthode à charge constante (ISO 1518-1:2019)

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. 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 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 va dépendre du problème pratique particulier.

Barve in laki - Ugotavljanje odpornosti proti razenju - 1. del: Metoda s konstantno obremenitvijo (ISO 1518-1:2019)

Ta dokument določa preskusno metodo za ugotavljanje odpornosti enopokrivnega ali večpokrivnega sistema barve, laka ali sorodnega izdelka proti prediranju pri razenju s praskalom, ki je obremenjeno z določenim bremenom, pri določenih pogojih. Praskalo prodre do podlage, razen v primeru večpokrivnega sistema, kjer praskalo lahko prodre do podlage ali vmesnega premaza.
Določeno metodo je mogoče izvesti
a) kot preskus »ustreznosti/neustreznosti« z določeno obremenitvijo praskala za oceno skladnosti s posebno specifikacijo ali
b) kot ocenjevalni preskus s povečevanjem obremenitve praskala za ugotavljanje najmanjše obremenitve, pri kateri pride do predora premaza.
OPOMBA: Niti ta dokument niti standard ISO 1518-2 ne določata metode z uporabo ukrivljenega praskala, ki je določena v standardu ISO 12137. Izbira ene od treh metod je odvisna od posameznega praktičnega problema.

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 second edition cancels and replaces the first edition (ISO 1518-1:2011), which has been technically

revised. The main changes compared to the previous edition are as follows:
— Clause 3, Terms and definitions, has been added;

— for the hard-metal tip, styli with tips of diameter 0,75 mm and 3,0 mm have been added;

— a description of the test panels has been added;
— scoring of the surface has been added to the evaluation;

— a requirement to examine the tip of the stylus for damage, contamination and smooth in appearance

has been added;
— Clauses 7 and 10 have been aligned to ISO 1518-2.
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

complete listing of these bodies can be found at www .iso .org/members .html.
