Gas cylinders - Compatibility of cylinder and valve materials with gas contents - Part 3: Autogenous ignition test for non-metallic materials in oxygen atmosphere (ISO 11114-3:2010)
ISO 11114-3:2010 specifies a test method to determine the autogenous ignition temperature of non-metallic materials in pressurized gaseous oxygen.
The autogenous ignition temperature is one criterion for ranking materials, and can be used to assist with the choice of materials used in the presence of gaseous oxygen.
A comprehensive bibliography of the published material on which ISO 11114-3:2010 is based is included.
It is intended that ISO 11114-3:2010 be used for the selection of non-metallic materials for gas cylinders and accessories, for example to select the materials in order to meet the requirement for type testing for oxygen compatibility of all cylinder valves for highly oxidizing gases as specified in ISO 10297.

Dieser Teil der ISO 11114 legt ein Prüfverfahren zur Bestimmung der Selbstentzündungstemperatur von
nichtmetallischen Werkstoffen in verdichtetem gasförmigem Sauerstoff fest.
Die Selbstentzündungstemperatur stellt eines der Kriterien für die Klassifizierung von Werkstoffen dar und
kann als Hilfe bei der Werkstoffauswahl für die Verwendung in gasförmigem Sauerstoff angewendet werden.
Es ist eine umfassende Bibliographie der Veröffentlichungen, auf denen diese Norm basiert, enthalten.
Es ist beabsichtigt, diesen Teil der ISO 11114 für die Auswahl von nichtmetallischen Werkstoffen für
Gasflaschen und Ausrüstungsteile anzuwenden, z. B. um die Werkstoffe auszuwählen, die die Anforderungen
der in der ISO 10297 angegebenen Baumusterprüfung hinsichtlich der Sauerstoffverträglichkeit aller
Gasflaschenventile für stark oxidierende Gase erfüllen.
Bouteilles à gaz - Compatibilité des matériaux de bouteilles et de robinets avec les contenus gazeux - Partie 3: Essai d'auto-inflammation des matériaux non métalliques sous atmosphère d'oxygène (ISO 11114-3:2010)
L'ISO 11114-3:2010 spécifie une méthode d'essai pour la détermination de la température d'auto-inflammation des matériaux non métalliques dans l'oxygène gazeux sous pression.
La température d'auto-inflammation est un critère de classement des matériaux; elle permet donc d'aider au choix des matériaux utilisés en présence d'oxygène gazeux.
Une bibliographie exhaustive de la documentation publiée sur laquelle se fonde l'ISO 11114-3:2010 est incluse.
Il est prévu d'utiliser l'ISO 11114-3:2010 pour le choix des matériaux non métalliques destinés aux bouteilles à gaz et à leurs accessoires, par exemple pour choisir les matériaux devant satisfaire aux exigences de l'essai de type pour la compatibilité avec l'oxygène de tous les robinets de bouteilles à gaz hautement comburants spécifiés dans l'ISO 10297.
Premične plinske jeklenke - Združljivost materialov za ventil in jeklenko s plinom - 3. del: Preskus samovžiga nekovinskih materialov v kisikovi atmosferi (ISO 11114-3:2010)
Ta del ISO 11114 opredeljuje preskusno metodo za določanje temperature samovžiga nekovinskih materialov v plinastem kisiku pod tlakom. Temperatura samovžiga je eden od kriterijev za razvrščanje materialov in se lahko uporablja kot pomoč pri izbiri materialov, ki se uporabljajo v prisotnosti plinastega kisika. Vključena je obsežna bibliografija objavljenih gradiv, na katerih temelji ta del ISO 11114. Mišljeno je, da se ta del ISO 11114 uporablja za izbiro nekovinskih materialov za plinske jeklenke in dodatke, na primer za izbiro materialov, ki bodo ustrezali zahtevam za tipsko preskušanje združljivosti s kisikom vseh ventilov za jeklenke pri močno oksidativnih plinih, kot določa ISO 10297.

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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
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.
This part of ISO 11114 was prepared by Technical Committee ISO/TC 58, Gas cylinders.
This second edition cancels and replaces the first edition (ISO 11114-3:1997). No significant technical
changes have been made.
ISO 11114 consists of the following parts, under the general title Gas cylinders — Compatibility of cylinder and
valve materials with gas contents:
⎯ Part 1: Metallic materials
⎯ Part 2: Non-metallic materials
⎯ Part 3: Autogenous ignition test for non-metallic materials in oxygen atmosphere
⎯ Part 4: Test methods for selecting metallic materials resistant to hydrogen embrittlement

Introduction
The following test method is referenced in ISO 11114-1 and ISO 11114-2.
Further information about oxygen compatibility is given in ISO 11114-1 and ISO 11114-2.
Other oxygen compatibility test methods include oxygen index (see ISO 4589-3), heat of combustion and
adiabatic compression on materials (see ISO 21010).
INTERNATIONAL STANDARD ISO 11114-3:2010(E)

Part 3:
Autogenous ignition test for non-metallic materials in oxygen
atmosphere
1 Scope
This part of ISO 11114 specifies a test method to determine the autogenous ignition temperature of non-
metallic materials in pressurized gaseous oxygen.
The autogenous ignition temperature is one criterion for ranking materials, and can be used to assist with the
choice of materials used in the presence of gaseous oxygen.
A comprehensive bibliography of the published material on which this part of ISO 11114 is based is included.
It is intended that this part of ISO 11114 be used for the selection of non-metallic materials for gas cylinders
and accessories, for example to select the materials in order to meet the requirement for type testing for
oxygen compatibility of all cylinder valves for highly oxidizing gases as specified in ISO 10297.
2 Principle
A small quantity of the test material is heated in pressurized oxygen. A continuous recording is made of
pressure and temperature in order to determine the point of autogenous ignition, at which point a sudden
increase in temperature and pressure is observed (this point is known as the autogenous ignition
temperature).
3 Preparation of test samples
Test samples shall be prepared in such a manner as to prevent contamination.
Test samples may be in liquid or solid form. In the case of solids, the material shall be finely divided. A sample
mass between 0,06 g and 0,5 g is used for each test.
This mass should be adjusted to take into consideration the volume of the test reaction chamber. A sample of
3 3
0,5 g in a test reaction chamber volume of between 30 cm and 250 cm has been found to be suitable.
4 Test apparatus
Figure 1 gives an example of a suitable test apparatus. The test sample is put into a small, carefully cleaned
inert sample holder, placed in a reaction chamber within an electric oven with sufficient power to raise
temperature at a constant rate as specified in Clause 6.
