Paints and varnishes - Determination of resistance to liquids - Part 5: Temperature-gradient oven method (ISO 2812-5:2018)

This document specifies a method, using a temperature-gradient oven, for determining the resistance of an individual-layer or multi-layer system of coating materials to the effects of liquids or paste-like products.
This method enables the testers to determine the effects of the test substance on the coating and, if necessary, to assess the damage to the substrate.

Peintures et vernis - Détermination de la résistance aux liquides - Partie 5: Méthode au four à gradient de température (ISO 2812-5:2018)

Le présent document spécifie une méthode utilisant un four à gradient de température pour déterminer la résistance d'un système de revêtement monocouche ou multicouche à l'action de liquides ou de produits pâteux.
Cette méthode permet aux opérateurs de déterminer l'effet de la substance d'essai sur le revêtement et, si nécessaire, d'évaluer la détérioration du subjectile.

Barve in laki - Ugotavljanje odpornosti proti tekočinam - 5. del: Metoda s pečjo s temperaturnim gradientom (ISO 2812-5:2018)

Ta dokument določa metodo s pečjo s temperaturnim gradientom za ugotavljanje odpornosti posamezne plasti ali večplastnih sistemov premazov proti učinkom tekočin ali izdelkov, podobnih pasti.
Ta metoda preskuševalcem omogoča določiti učinke preskušane snovi na premaz in po potrebi oceniti škodo na podlagi.

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.

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 2812-5:2007), which has been technically
revised. The main changes compared to the previous edition are as follows:
a) Clause 3 and Clause 5 have been added;
b) in 6.1, the description of the gradient oven has been amended;
c) in 10.3, the distance of the individual heating segments for a temperature increase of 1 °C has been
clarified to 1 cm;
d) in Clause 11, reference to ISO 13076 has been made for the lighting and procedure for visual
assessment;
e) in Annex A, the CAS numbers have been added to the reagents listed.
