Vitreous and porcelain enamel finishes - Guide to selection of test methods for vitreous and porcelain enamelled areas of articles (ISO 4528:2015)
ISO 4528:2015 is a guide to the selection of test methods for evaluating the performance of vitreous and porcelain enamelled finishes in different applications. It references the test methods available for measuring the properties of these finishes and correlates these properties to the requirements of specific enamelled articles.
It is limited for the most part to test methods that are described in International Standards or European Standards and does not provide acceptance criteria or performance limits for the properties.
ISO 4528:2015 applies to all enamelled articles irrespective of their basis metals.

L'ISO 4528:2015 constitue un guide pour le choix des méthodes d'essai permettant l'évaluation des performances de finitions en émail vitrifié destinées à diverses applications. Elle fournit la référence des méthodes d'essai existantes permettant de mesurer les propriétés de ces finitions, et établit la relation entre ces propriétés et les exigences propres à certaines pièces émaillées particulières.
Elle se limite dans sa plus grande partie aux méthodes d'essai qui sont documentées dans des Normes internationales ou dans des Normes européennes. Néanmoins, elle ne fournit ni les critères d'approbation ni les limites de performance pour lesdites propriétés.
L'ISO 4528:2015 est applicable à toutes les pièces émaillées quel que soit leur métal de base.
Steklasti in porcelanski zaključni emajli - Vodilo za izbor preskusnih metod za emajlirane površine izdelkov (ISO 4528:2015)
Ta mednarodni standard je vodilo za izbor preskusnih metod za ocenjevanje površine steklastih in porcelanskih zaključnih emajlov pri različnih namenih uporabe. Sklicuje se na preskusne metode, ki so na voljo za merjenje lastnosti teh emajlov, ter te lastnosti povezuje z zahtevami za določene emajlirane izdelke.
V večjem delu je omejen na preskusne metode, opisane v mednarodnih standardih ISO/evropskih standardih, in za lastnosti ne podaja meril glede sprejemljivosti ali omejitev kakovosti.
Ta mednarodni standard se uporablja za vse emajlirane izdelke, ne glede na to, katere so njihove osnovne kovine.

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

Introduction
Standard test methods are required for measuring and controlling the properties and hence also the
quality of vitreous and porcelain enamelled finishes.
To ensure that these finishes meet the requirements of various applications, test methods have to be
chosen to measure the properties that are important to the function of a specific enamelled article.
INTERNATIONAL STANDARD ISO 4528:2015(E)
Vitreous and porcelain enamel finishes — Guide to
selection of test methods for vitreous and porcelain
enamelled areas of articles
WARNING — This International Standard might not be compliant with some countries’ health and
safety legislation and calls for the use of substances and/or procedures that can be injurious to
health if adequate safety measures are not taken. This International Standard does not address
any health hazards, safety, or environmental matters and legislations associated with its use. It
is the responsibility of the user of this International Standard to establish appropriate health,
safety, and environmentally acceptable practices and take suitable actions to comply with any
national and international regulations. Compliance with this International Standard does not of
itself confer immunity from legal obligations.
1 Scope
This International Standard is a guide to the selection of test methods for evaluating the performance
of vitreous and porcelain enamelled finishes in different applications. It references the test methods
available for measuring the properties of these finishes and correlates these properties to the
requirements of specific enamelled articles.
It is limited for the most part to test methods that are described in ISO International/European Standards
and does not provide acceptance criteria or performance limits for the properties.
This International Standard applies to all enamelled articles irrespective of their basis metals.
2 Selection of test methods
The properties of enamelled surfaces are listed in Table 1, along with the numbers of the ISO test methods
by which they may be measured. The table identifies the tests that should be performed to assess the
performance of 30 specific enamelled articles. Suitable standard test methods are selected by noting the
specific tests recommended in the column for each of the enamelled articles.
The following symbols are used in Table 1.
— + testing in accordance with the method given is suitable;
— (+) the test method that is cited may need to be modified to take into account special require-
ments of a specific application;
— - the test is not applicable and/or the test method is not suitable.
