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

This document 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: Anleitung (ISO 4589-1:2017)

Dieser Teil von ISO 4589 enthält eine Anleitung für die Bestimmung des Brennverhaltens mittels Sauerstoff-Index. Er gibt Informationen, um den Leser bei der Anwendung der in den Teilen 2 und 3 beschriebenen Prüfverfahren anzuleiten.
In Teil 2 wird 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, beschreiben. Die Ergebnisse werden als OI Werte definiert. Zu Vergleichszwecken wird außerdem ein Verfahren geliefert, mit dem bestimmt werden kann, ob der OI eines Werkstoffes über einem festgelegten Mindestwert liegt, der besonders für die Qualitätskontrolle von Bedeutung ist. Außerdem gibt es ein Verfahren, mit dem dünne Folien, die zwischen 20 µm und 100 µm dick sind, geprüft werden können.
In Teil 3 werden Verfahren beschrieben, 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 dürfen). Die Ergebnisse werden als TI (Temperaturindex)-Werte bei der Prüftemperatur definiert. In Teil 3 wird auch ein Verfahren zur Bestimmung der Temperatur beschrieben, bei der der OI Wert bei kleinen senkrecht angeordneten Probekörpern 20,9 % beträgt. Das Ergebnis wird als Entflammbarkeitstemperatur definiert. Teil 3 ist nicht auf Werkstoffe anwendbar, deren OI Wert bei einer Temperatur von 23 °C weniger als 20,9 % beträgt.

Plastiques - Détermination du comportement au feu au moyen de l'indice d'oxygène - Partie 1: Lignes directrices (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).

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.

DRAFT INTERNATIONAL STANDARD ISO/DIS 4589-1

Plastics — Determination of burning behaviour by oxygen
index — Part 1: Guidance
1 Scope
This part of ISO 4589 constitutes a guidance document for the OI test. It provides information to guide the
reader in the use of the test procedures described in parts 2 and 3.
Part 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. The results are defined as OI values. For comparative purposes, a procedure is also provided for
determining whether or not the OI of a material lies above some specified minimum value, which is particularly
important for quality control purposes. There is also a procedure for the testing of thin films between 20 μm
and 100 μm thickness
Part 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 may be used). The results are defined as TI
(Temperature Index) values at the test temperature. Part 3 also describes a method for determining the
temperature at which the OI of the small vertical test specimens is 20,9 %. The result is defined as the
flammability temperature. Part 3 is not applicable to materials having an OI value of less than 20,9 % at 23 °C.
