Paints and varnishes - Determination of scratch resistance - Part 2: Variable-loading method (ISO 1518-2:2019)

This document specifies a method for determining, using a pointed stylus loaded with a continuously increasing load, the scratch resistance of a single coating of a paint, varnish or related product, or the upper layer of a multicoat system.
This test has been found to be useful in comparing the scratch resistance of different coatings. It is most useful in providing relative ratings for a series of coated panels exhibiting significant differences in scratch resistance.
NOTE       Neither this document nor ISO 1518‑1 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 2: Verfahren mit kontinuierlich ansteigender Last (ISO 1518-2:2019)

Dieses Dokument legt ein Verfahren zum Bestimmen der Widerstandsfähigkeit einer einzelnen Schicht aus einem Beschichtungsstoff oder der obersten Schicht eines Mehrschichtsystems gegen Kratzer fest, bei dem ein spitzer Stichel mit einer kontinuierlich ansteigenden Last verwendet wird.
Diese Prüfung wurde zum Vergleich der Kratzbeständigkeit unterschiedlicher Beschichtungen als nützlich befunden. Sie ist besonders geeignet, wenn bei einer Reihe beschichteter Probenplatten mit deutlich unter¬schiedlicher Kratzbeständigkeit relative Einstufungen erhalten werden sollen.
ANMERKUNG   Weder dieses Dokument noch ISO 1518 1 legen ein Verfahren mit einem gebogenen Stichel fest, das in ISO 12137 festgelegt ist. Welches der drei Verfahren gewählt wird, hängt von der jeweiligen Fragestellung ab.

Peintures et vernis - Détermination de la résistance à la rayure - Partie 2: Méthode à charge variable (ISO 1518-2:2019)

Le présent document spécifie une méthode pour la détermination, à l'aide d'un stylet pointu auquel une charge augmentant de manière continue est appliquée, de la résistance à la rayure d'une couche unique de peinture, de vernis ou de produit assimilé, ou de la couche supérieure d'un système multicouche.
Cet essai s'est avéré utile pour comparer la résistance à la rayure de différents revêtements. Il permet notamment de fournir des valeurs comparatives pour une série de panneaux revêtus présentant des différences significatives de résistance à la rayure.
NOTE       Ni le présent document ni l'ISO 1518-1 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 - 2. del: Metoda s stopnjevano obremenitvijo (ISO 1518-2:2019)

Ta dokument določa metodo za ugotavljanje odpornosti proti razenju enopokrivnega sistema barve, laka ali sorodnega izdelka ali zgornjega sloja večpokrivnega sistema proti razenju z ostro ošiljenim praskalom s stalnim povečanjem obremenitve.
Ta preskus se je izkazal za uporabnega pri primerjavi odpornosti proti razenju različnih premazov. Predvsem uporaben je za zagotavljanje relativnih vrednosti za serije premazanih plošč, ki se precej razlikujejo v odpornosti proti razenju.
OPOMBA: Niti ta dokument niti standard ISO 1518-1 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.

Overview

EN ISO 1518-2:2019 - Paints and varnishes: Determination of scratch resistance - Part 2: Variable‑loading method - specifies a laboratory test for measuring the scratch resistance of a single coating or the upper layer of a multicoat system using a pointed stylus with a continuously increasing load. The method produces comparative, relative ratings useful when coated panels show significant differences in scratch performance.

Key topics and technical requirements

• Scope: Scratch resistance measured with a pointed stylus under continuously increasing load; intended for single coats or top layers of multilayer systems.
• Apparatus: Typical instrument has a counterbalanced beam, a pointed stylus (conical sapphire or diamond tip), and a motor‑driven sliding table. The panel moves beneath the stylus at 10 mm/s while loading increases continuously.
• Stylus details: Tip rounded to a radius of (0.030 ± 0.005) mm (conical sapphire or diamond recommended).
• Loading ranges: Variable by changing continuous‑loading weights and adding pan weights (examples: 0–50 g, 0–100 g, 0–200 g; extensible by added masses).
• Specimen preparation and sampling: Panels prepared and coated per ISO 1514 and sampling per ISO 15528. Dry‑film thickness determined per ISO 2808.
• Conditioning: Panels conditioned at (23 ± 2) °C and (50 ± 5) % RH for a minimum of 16 hours (ISO 3270).
• Inspection & reporting: Use microscope (up to ×100) to inspect scratches and stylus. Test report should include coating application method, drying/stoving and ageing conditions, film thickness, apparatus and loading ranges, and test results.
• Limitations: Best suited for comparative testing of coatings with significant differences in scratch resistance. This part does not cover curved‑stylus methods (see ISO 12137).

Applications and users

• Quality control and comparative evaluation of paints, varnishes and clearcoats.
• Coating formulators and R&D teams developing scratch‑resistant systems.
• Independent testing laboratories and certification bodies performing standardized scratch testing.
• Industry sectors: automotive, aerospace, furniture, flooring, architectural and industrial coatings where surface durability and scratch performance are critical.

Related standards

• ISO 1518‑1 (other scratch methods)
• ISO 12137 (curved stylus method)
• ISO 1513, ISO 1514, ISO 2808, ISO 3270, ISO 4618, ISO 15528

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.
