Plastics - Determination of burning behaviour by oxygen index - Part 2: Ambient-temperature test (ISO 4589-2:2017)
ISO 4589-2:2017 specifies methods for determining the minimum volume fraction of oxygen, in admixture with nitrogen, that will support combustion of small vertical test specimens under specified test conditions. The results are defined as oxygen index (OI) values.
Methods are provided for testing materials that are self-supporting in the form of vertical bars or sheets up to 10,5 mm thick. These methods are suitable for solid, laminated or cellular materials characterized by an apparent density 100 kg/m3 or greater. The methods might also be applicable to some cellular materials having an apparent density of less than 100 kg/m3. A method is provided for testing flexible sheets or film materials while supported vertically.
For comparative purposes, a procedure is provided for determining whether or not the OI of a material lies above some specified minimum value.
Kunststoffe - Bestimmung des Brennverhaltens durch den Sauerstoff-Index - Teil 2: Prüfung bei Umgebungstemperatur (ISO 4589-2:2017)
Dieses Dokument legt Verfahren zur Bestimmung des minimalen Volumenanteils an Sauerstoff in Gemischen mit Stickstoff fest, bei dem die Verbrennung senkrecht angeordneter kleiner Probekörper unter festgelegten Prüfbedingungen unterstützt wird. Die Ergebnisse sind als Sauerstoff-Index-Werte (OI, en: oxygen index) definiert.
Es werden Verfahren für die Prüfung von Werkstoffen angegeben, die als senkrechte Stäbe oder Platten von maximal 10,5 mm Dicke selbsttragend sind. Diese Verfahren sind für feste und beschichtete Werkstoffe oder Schaumstoffe mit einer Rohdichte von 100 kg/m3 oder größer geeignet. Die Verfahren dürfen auch auf einige Schaumstoffe angewendet werden, deren Rohdichte weniger als 100 kg/m3 beträgt. Es wird ein Verfahren zur Prüfung senkrecht gehaltener flexibler Platten- oder Folienwerkstoffe beschrieben.
Für Vergleichszwecke wird ein Verfahren angegeben, mit dem bestimmt werden kann, ob der Sauerstoff-Index von einem Werkstoff über einem festgelegten Mindestwert liegt.
ANMERKUNG Diese Verfahren sind unter Umständen auf Werkstoffe mit großem Schrumpf bei Erwärmung, z. B. stark gereckte dünne Folien, nicht zufriedenstellend anwendbar.
Plastiques - Détermination du comportement au feu au moyen de l'indice d'oxygène - Partie 2: Essai à la température ambiante (ISO 4589-2:2017)
ISO 4589-2:2017 spécifie des méthodes pour la détermination de la fraction volumique minimale d'oxygène, dans un mélange oxygène/azote, qui permet d'entretenir la combustion de petites éprouvettes verticales dans des conditions d'essai spécifiées. Les résultats sont définis en tant que valeurs de l'indice d'oxygène (OI).
Les méthodes sont définies pour les essais de matériaux autoportants sous forme de barreaux verticaux ou de feuilles ayant une épaisseur maximale de 10,5 mm. Ces méthodes sont utilisables pour les matériaux compacts, stratifiés ou alvéolaires ayant une masse volumique apparente supérieure ou égale à 100 kg/m3. Elles peuvent également être applicables à certains matériaux alvéolaires ayant une masse volumique apparente inférieure à 100 kg/m3. Une méthode comportant un support vertical est également prévue pour les films et feuilles souples.
Un procédé permettant de déterminer si l'OI d'un matériau se situe ou non au-dessus d'une valeur minimale spécifiée est donné afin de pouvoir établir des comparaisons.
Polimerni materiali - Določanje gorljivosti s kisikovim indeksom - 2. del: Preskus pri sobni temperaturi (ISO 4589-2:2017)
Ta dokument opisuje metodo za določanje najmanjšega prostorninskega deleža kisika v mešanici in z dušikom, namenjeni za podporo pri zgorevanju majhnih navpičnih preskušancev pri določenih preskusnih pogojih. Rezultati so opredeljeni kot vrednosti kisikovega indeksa.
Zagotovljene so metode za preskušanje samonosnih materialov v obliki navpičnih palic ali plošč debeline do 10,5 mm. Te metode so primerne za trdne, laminirane ali penjene materiale, za katere je značilna gostota 100 kg/m3 ali več. Metode se lahko uporabijo tudi pri nekaterih penjenih materialih z gostoto manj kot 100 kg/m3. Metoda je zagotovljena za preskušanje prožnih plošč ali tankoplastnih materialov, ki so navpično podprti.
Za primerjavo je zagotovljen postopek za določanje, ali je kisikov indeks materiala
nad neko določeno minimalno vrednostjo.
OPOMBA: Teh metod morda ne bo mogoče uporabiti v zadovoljivi meri pri materialih, ki se zaradi segrevanja močno krčijo, npr. tankoslojni materiali.
