Plastics - Thermogravimetry (TG) of polymers - Part 1: General principles (ISO 11358-1:2014)
EN ISO 11358-1 specifies general conditions for the analysis of polymers using thermogravimetric techniques. It is applicable to liquids or solids. Solid materials may be in the form of pellets, granules or powders. Fabricated shapes reduced to appropriate specimen size may also be analysed by this method. Thermogravimetry 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. The thermogravimetric measurements may be carried out in dynamic mode (mass change versus temperature or time under programmed conditions) or isothermal mode (mass change versus time at constant temperature). Thermogravimetric measurements may also be carried out using different testing atmospheres, e.g. to separate decomposition in an inert atmosphere from oxidative degradation.
Kunststoffe - Thermogravimetrie (TG) von Polymeren - Teil 1: Allgemeine Grundsätze (ISO 11358-1:2014)
Diese Internationale Norm legt allgemeine Bedingungen für die thermogravimetrische Analyse von Polymeren fest. Sie ist anwendbar auf flüssige und 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.
Die Thermogravimetrie 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.
Thermogravimetrische Messungen können mit einem dynamischen Verfahren (Massenänderung in Abhängigkeit von der Temperatur oder Zeit unter programmierten Bedingungen) oder einem isothermen Verfahren (Massenänderung in Abhängigkeit von der Zeit bei konstanter Temperatur) durchgeführt werden.
Thermogravimetrische Messungen können ebenfalls unter Anwendung unterschiedlicher Prüfatmosphären durchgeführt werden, um beispielsweise die Zersetzung in einer inerten Atmosphäre von der oxidativen Zersetzung zu trennen.
Plastiques - Thermogravimétrie (TG) des polymères - Partie 1: Principes généraux (ISO 11358-1:2014)
L'ISO 11358-1:2014 spécifie les conditions générales d'analyse des polymères au moyen des techniques de thermogravimétrie. Elle est applicable aux liquides et aux solides. Les matériaux solides peuvent se présenter sous forme de granulés, de grains ou de poudre. Cette méthode d'analyse est également applicable aux objets façonnés sur lesquels une éprouvette de dimensions appropriées est prélevée.
Polimerni materiali - Termogravimetrija (TG) polimerov - 1. del: Splošna načela (ISO 11358-1:2014)
Standard EN ISO 11358-1 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 se lahko analizira tudi izdelane oblikovance, prilagojene ustrezni velikosti preskušanca. S termogravimetrijo je mogoče določiti temperaturo(e) in stopnjo(e) razgradnje polimerov ter obenem izmeriti količine hlapnih snovi, aditivov in/ali polnil, ki jih polimeri vsebujejo. Termogravimetrijske meritve se lahko izvede dinamično (sprememba mase v primerjavi s temperaturo ali časom v programiranih razmerah) ali izotermno (sprememba mase v primerjavi s časom pri stalni temperaturi). Termogravimetrijske meritve se lahko izvede tudi v različnih preskusnih atmosferah, npr. da razgradnjo v inertni atmosferi zavarujete pred oksidativnim poslabšanjem.

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).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

assessment, as well as information about ISO’s adherence to the WTO principles in the Technical Barriers
to Trade (TBT) see the following URL: Foreword - Supplementary information

properties.
This first edition of ISO 11358-1 cancels and replaces ISO 11358:1997, which has been technically revised.
The main changes are:
a) addition of ISO 472 to the Normative references clause and removal of definitions specified therein;
b) revision of apparatus specifications.
ISO 11358 consists of the following parts, under the general title Plastics — Thermogravimetry (TG) of

The change in mass is recorded as a thermogravimetric (TG) curve.The change in mass of a material as a function of temperature and the extent of this change are indicators of the thermal stability of the materialä TG data can therefore be used to evaluate the relative thermal stability of polymers of the same generic family and polymeræpolymer or polymeræadditive interactionsá using measurements made under the same test conditions.NOTE TG data may be used for process controlá process development and material evaluationä Longæterm thermal stability is a complex function of service and environmental condition
