Overview
ISO 2245:2006 is an international standard developed by the International Organization for Standardization (ISO) that specifies the classification of shaped insulating refractory products. These specialized materials are designed for thermal insulation in high-temperature environments, featuring a significant porosity level that ensures low thermal conductivity and reduced heat capacity. The classification focuses primarily on the permanent dimensional change these materials experience under heat treatment, with a secondary classification based on bulk density to identify lightweight products, denoted as Class L. Notably, ceramic fiber products are excluded from this classification.
This standard is essential for manufacturers, engineers, and quality control professionals involved in selecting and verifying insulating refractory products for industrial applications involving heat insulation and refractory linings.
Key Topics
Classification Basis
The classification relies on two main criteria:- Permanent Dimensional Change: Testing at various temperatures to determine the extent of size change after heating, with limits set to a maximum of 2%.
- Bulk Density: Measuring apparent density to identify lightweight insulating materials within Class L, ensuring proper categorization of materials with high porosity.
Temperature Groupings
Products are grouped according to the temperature at which dimensional stability testing is conducted, ranging from 800 °C to 1800 °C in increments of 100 °C. This enables precise matching of insulating refractories to operational temperature requirements.Testing Standards Referenced
Compliance with associated ISO testing methods is mandated:- ISO 2477: Measuring permanent dimensional change on heating.
- ISO 5016: Determining apparent density and true porosity.
- ISO 836: Terminology of refractory materials.
Designation System
The standard defines a systematic product designation format including the ISO reference, temperature group, apparent density, and Class L status if applicable, for clear product identification and specification.
Applications
ISO 2245:2006 classification assists industries where thermal insulation under high temperatures is crucial, including:
- Metallurgical Industry: Lining of furnaces, kilns, and ladles requiring stable, insulating refractory materials that maintain their shape under extreme heat.
- Ceramics and Glass Production: Insulation components needing consistent performance at operational temperatures to maintain energy efficiency.
- Power Plants and Incinerators: Insulating refractory parts ensuring structural integrity and thermal efficiency in combustion chambers.
- Chemical Processing: High-temperature reactors and vessels which demand dimensionally stable insulation materials.
Utilizing ISO 2245-compliant products helps in optimizing energy consumption, enhancing safety, and prolonging the service life of refractory installations.

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.
ISO 2245 was prepared by Technical Committee ISO/TC 33, Refractories.
This third edition cancels and replaces the second edition (ISO 2245:1990), Clauses 3 and 5 and Tables 1
and 2 of which have been technically revised.

Avant-propos
L'ISO (Organisation internationale de normalisation) est une fédération mondiale d'organismes nationaux de
normalisation (comités membres de l'ISO). L'élaboration des Normes internationales est en général confiée
aux comités techniques de l'ISO. Chaque comité membre intéressé par une étude a le droit de faire partie du
comité technique créé à cet effet. Les organisations internationales, gouvernementales et non
gouvernementales, en liaison avec l'ISO participent également aux travaux. L'ISO collabore étroitement avec
la Commission électrotechnique internationale (CEI) en ce qui concerne la normalisation électrotechnique.
Les Normes internationales sont rédigées conformément aux règles données dans les Directives ISO/CEI,
Partie 2.
La tâche principale des comités techniques est d'élaborer les Normes internationales. Les projets de Normes
internationales adoptés par les comités techniques sont soumis aux comités membres pour vote. Leur
publication comme Normes internationales requiert l'approbation de 75 % au moins des comités membres
votants.
