Plastics - Thermogravimetry (TG) of polymers - Part 1: General principles (ISO 11358-1:2022)

This document specifies general conditions for the analysis of polymers using thermogravimetric techniques. It is applicable to liquids or solids. Solid materials can be in the form of pellets, granules or powders. Fabricated shapes reduced to appropriate specimen size can also be analysed by this method.
This document establishes methods for the investigation of physical effects and chemical reactions that are associated with changes of mass.
This document can be used to determine the temperature(s) and rate(s) of decomposition of polymers, and to measure at the same time the amounts of volatile matter, additives and/or fillers they contain.
This document is applicable to measurements in dynamic mode (mass change versus temperature or time under programmed temperature conditions) or isothermal mode (mass change versus time at constant temperature).
This document is applicable to measurements at different testing atmospheres, such as separation of decomposition in an inert atmosphere from oxidative degradation.

Kunststoffe - Thermogravimetrie (TG) von Polymeren - Teil 1: Allgemeine Grundsätze (ISO 11358-1:2022)

Dieses Dokument legt allgemeine Bedingungen für die thermogravimetrische Analyse von Polymeren fest. Es ist anwendbar auf flüssige oder feste Stoffe. Die festen Stoffe können als Pellets, Granulat oder Pulver vorliegen. Mit dem Verfahren können ebenfalls auf eine geeignete Probekörpergröße reduzierte Fertigteile untersucht werden.
Dieses Dokument legt Verfahren zur Untersuchung von physikalischen Effekten und chemischen Reaktionen fest, die mit Massenänderungen verbunden sind.
Dieses Dokument kann zur Bestimmung der Temperatur(en) und der Zersetzungsrate(n) von Polymeren und zur gleichzeitigen Messung der Menge der darin enthaltenen flüchtigen Anteile, Zusatzstoffe und/oder Füllstoffe angewendet werden.
Dieses Dokument gilt für Messungen mit einem dynamischen Verfahren (Massenänderung in Abhängigkeit von der Temperatur oder Zeit unter programmierten Temperaturbedingungen) oder einem isothermen Verfahren (Massenänderung in Abhängigkeit von der Zeit bei konstanter Temperatur).
Dieses Dokument gilt für Messungen unter Anwendung unterschiedlicher Prüfatmosphären, wie z. B. die Zersetzung in einer inerten Atmosphäre von der oxidativen Zersetzung zu trennen.

Plastiques - Thermogravimétrie (TG) des polymères - Partie 1: Principes généraux (ISO 11358-1:2022)

Le présent document spécifie les conditions générales d’analyse des polymères au moyen des techniques de thermogravimétrie. Il est applicable aux liquides et aux solides. Les matériaux solides peuvent se présenter sous forme de granulés, de grains ou de poudre.

Le présent document établit des méthodes pour l’étude des effets physiques et des réactions chimiques qui sont associés aux variations de masse.
Le présent document peut être utilisé pour déterminer la/les température(s) et le(s) taux de décomposition des polymères et pour mesurer simultanément les quantités de matières volatiles, d’additifs et/ou de charges qu’ils contiennent.
Le présent document est applicable aux mesurages selon un mode dynamique (variation de masse en fonction de la température ou du temps, dans des conditions de température définies) ou un mode isotherme (variation de masse en fonction du temps, à température constante).
Le présent document est applicable aux mesurages en employant différentes atmosphères d’essai, tels que la séparation d’une décomposition dans une atmosphère inerte à partir d’une dégradation oxydative.

Polimerni materiali - Termogravimetrija (TG) polimerov - 1. del: Splošna načela (ISO 11358-1:2022)

Ta dokument določa splošne pogoje za analizo polimerov z uporabo termogravimetrijskih tehnik. Uporablja se za tekočine ali trdne snovi. Trdni materiali imajo lahko obliko peletov, granul ali praškov. S to metodo je mogoče analizirati tudi izdelane oblikovance, prilagojene ustrezni velikosti preskušanca. Ta dokument določa metode za raziskovanje fizikalnih učinkov in kemijskih reakcij, povezanih s spremembami mase. Dokument je mogoče uporabiti za določanje temperatur in stopenj razgradnje polimerov ter obenem izmeriti količine hlapnih snovi, aditivov in/ali polnil, ki jih polimeri vsebujejo. Ta dokument se uporablja za dinamične meritve (sprememba mase v primerjavi s temperaturo ali časom v programiranih razmerah) ali izotermno (sprememba mase v primerjavi s časom pri stalni temperaturi). Ta dokument se uporablja za meritve pri različnih preskusnih atmosferah, kot je ločevanje razgradnje v inertni atmosferi od oksidativne razgradnje.

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
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).

This document was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 5, Physical
chemical properties, in collaboration with the European Committee for Standardization (CEN) Technical
Committee CEN/TC 249, Plastics, in accordance with the Agreement on technical cooperation between

This second edition cancels and replaces the first edition (ISO 11358-1:2014), which has been technically
revised. The main changes compared to the previous edition are as follows:
— a normative reference to ISO 472 has been added;
— definitions specified in ISO 472 have been removed;
— measurement under reactive atmosphere has been added;
— the apparatus specifications have been changed;
— the calibration procedures have been revised;
— buoyancy correction has been added;
— use of a differential thermogravimetric curve has been added.
