Plastics - Determination of burning behaviour by oxygen index - Part 1: General requirements (ISO 4589-1:2017)

ISO 4589-1:2017 specifies the general requirements for the oxygen index (OI) test which are further described in ISO 4589‑2 and ISO 4589‑3 as follows:
-      ISO 4589‑2 describes a method for determining the minimum volume fraction of oxygen in a mixture of oxygen and nitrogen introduced at 23 °C ± 2 °C that will just support combustion of a material under specified test conditions;
-      ISO 4589‑3 describes methods of carrying out the same determination over a range of temperatures typically between 25 °C and 150 °C (although temperatures up to 400 °C can be used).

Kunststoffe - Bestimmung des Brennverhaltens durch den Sauerstoff-Index - Teil 1: Allgemeine Anforderungen (ISO 4589-1:2017)

Dieses Dokument legt die allgemeinen Anforderungen an die Sauerstoff Index (OI)-Prüfung fest, die weitergehend in ISO 4589 2 und ISO 4589 3 wie folgt beschrieben werden:
-   ISO 4589 2 beschreibt ein Verfahren zur Bestimmung des minimalen Volumenanteils an Sauerstoff in einem Gemisch aus Sauerstoff und Stickstoff, das bei einer Temperatur von (23 ± 2) °C zugegeben wird und die Verbrennung eines Werkstoffes unter festgelegten Prüfbedingungen gerade noch unterstützt;
-   ISO 4589 3 beschreibt Verfahren, mit denen die gleiche Bestimmung über einen Temperaturbereich durchgeführt werden kann, der üblicherweise zwischen 25 °C und 150 °C liegt (obwohl Temperaturen bis zu 400 °C angewendet werden können).

Plastiques - Détermination du comportement au feu au moyen de l'indice d'oxygène - Partie 1: Exigences générales (ISO 4589-1:2017)

ISO 4589-1:2017 spécifie les exigences générales pour l'essai de l'indice d'oxygène (OI) qui est décrit dans l'ISO 4589‑2 et l'ISO 4589‑3 comme suit:
-      l'ISO 4589‑2 décrit une méthode de détermination de la fraction volumique minimale d'oxygène, dans un mélange oxygène-azote introduit à 23 °C ± 2 °C, qui est juste nécessaire au maintien de la combustion du matériau dans les conditions d'essai spécifiées.
-      l'ISO 4589‑3 décrit des méthodes qui permettent de procéder à la même détermination sur une plage de températures allant, généralement, de 25 °C à 150 °C (bien qu'il soit possible de mettre en ?uvre des températures allant jusqu'à 400 °C).

Polimerni materiali - Določanje gorljivosti s kisikovim indeksom - 1. del: Splošne zahteve (ISO 4589-1:2017)

Ta dokument določa splošne zahteve za preskus kisikovega indeksa (OI), ki so podrobneje opisane v standardih ISO 4589-2 in ISO 4589-3:
– ISO 4589-2 opisuje metodo za določanje najmanjšega prostorninskega deleža kisika v mešanici kisika in dušika pri 23 °C ± 2 °C, namenjeni zgolj za podporo pri zgorevanju materiala pri določenih preskusnih pogojih;
– ISO 4589-3 opisuje metodo za izvedbo enakega določanja pri običajnem temperaturnem razponu 25–150 °C (čeprav se lahko uporabijo temperature do 400 °C).

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).

patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of

ISO 4589-1:2017(E)
Introduction
[3]
The oxygen index (OI) test at ambient temperature was first described by Fenimore and Martin in
0[2]
1966. The first use of the method in standards was ASTM D2863: 197 and it has since been published
in a wide range of national and international standards. It was published as ISO 4589 in 1984 and has
now been revised as ISO 4589-2. The OI test at elevated temperatures is described in ISO 4589-3.
In the period since ASTM D2863 became a standard, a considerable number of papers have been
published about this test. An example is the review in Reference [6] relating to the relevance of the
test to real fire situations. Other papers have suggested empirical formulae relating OI to the amounts
of added fire retardant, or describe practical investigations on the equipment performance (see
Reference [7]). A clear consensus on the value of the two variants of the test has emerged, however, and
it is the purpose of this document to discuss the use of the equipment and the applicability of both test
methods.
