Plastics - Polypropylene and propylene-copolymers - Determination of thermal oxidative stability in air - Oven method (ISO 4577:2019)
This standard specifies a method for the determination of the resistance of moulded test specimens of polypropylene and propylene-copolymers to accelerated ageing by heat in the presence of air using a forced draught oven. The method represents an attempt to estimate the service life of parts fabricated from propylene plastics. The stability determined by this method is not directly related to the suitability of the material for use when different environmental conditions prevail.
Kunststoffe - Polypropylen und Propylen-Copolymere - Bestimmung der thermischen Oxidationsstabilität in Luft - Ofen-Verfahren (ISO 4577:2019)
Dieses Dokument legt ein Verfahren zur Bestimmung des Widerstandes geformter Probekörper aus Polypropylen und Propylen Copolymeren gegen beschleunigte Alterung durch Wärme in Gegenwart von Luft fest, wobei ein Ofen mit Zwangsbelüftung angewandt wird.
Mit dem Verfahren wird versucht, die Gebrauchsdauer von aus Propylen hergestellten Kunststoffteilen einzuschätzen.
Die nach diesem Verfahren bestimmte Stabilität steht nicht in direktem Verhältnis zur Gebrauchstauglichkeit des Werkstoffes bei Vorherrschen anderer Umgebungsbedingungen.
ANMERKUNG Die angegebenen Temperaturbereiche werden als ausreichend hoch angesehen, um bei handels-üblichen Qualitäten wärmebeständiger Propylenkunststoffe innerhalb einer vertretbaren Zeit zur Schädigung zu führen. Falls dies gewünscht wird, können bei der Einschätzung der Gebrauchsleistung von Propylenkunststoffen mit geringerer Wärmestabilität niedrigere Temperaturen angewandt werden.
Plastiques - Polypropylène et copolymères de propylène - Détermination de la stabilité à l'oxydation à chaud dans l'air - Méthode à l'étuve (ISO 4577:2019)
Le présent document spécifie une méthode de détermination de la résistance d'éprouvettes moulées, en polypropylène ou copolymères de propylène, au vieillissement accéléré à la chaleur en présence d'air, dans une étuve à circulation d'air forcé.
La méthode représente une tentative d'estimation de la durée de vie en service des pièces en plastiques propyléniques.
La stabilité déterminée par la présente méthode n'est pas directement liée à l'aptitude du matériau à une utilisation dans différentes conditions d'environnement.
NOTE Les niveaux thermiques spécifiés sont considérés comme suffisamment sévères pour entraîner la dégradation, en un temps raisonnable, des types commerciaux de plastiques propyléniques résistant à la chaleur. Si on le désire, des températures plus basses peuvent être appliquées pour estimer les performances de types de plastiques propyléniques de stabilité plus faible à la chaleur.
Polimerni materiali - Polipropilen in kopolimeri propilena - Določanje termično-oksidativne stabilnosti na zraku - Metoda s pečjo (ISO 4577:2019)
Ta standard določa metodo za določitev odpornosti oblikovanih preskusnih vzorcev iz polipropilena in propilen-kopolimerov proti pospešenemu staranju zaradi vročine v prisotnosti zraka s pomočjo peči s prisilnim vpihovanjem zraka. Z metodo se poskuša oceniti življenjska doba delov, izdelanih iz propilenskih polimerov. Stabilnost, določena s to metodo, ni neposredno povezana s primernostjo materiala za uporabo v različnih okoljskih pogojih.

Oven method
1 Scope
This document specifies a method for the determination of the resistance of moulded test specimens
of polypropylene and propylene-copolymers to accelerated ageing by heat in the presence of air using a
forced draught oven.
The method represents an attempt to estimate the service life of parts fabricated from propylene
plastics.
The stability determined by this method is not directly related to the suitability of the material for use
when different environmental conditions prevail.
NOTE The specified thermal levels are considered sufficiently severe to cause failure of commercial grades
of heat-stable propylene plastics within a reasonable period of time. If desired, lower temperatures can be applied
to estimate the performance of propylene plastics with lower heat stabilities
