Insulating refractory products - Part 1: Terminology, classification and methods of test for high temperature insulation wool products
This European Standard defines terms for those refractory products and materials which are classed as high temperature insulation wools (HTIW). It also establishes the classification of insulating refractory products made from HTIW and specifies methods for determining the thickness, bulk density, resilience, permanent linear change and tensile strength of HTIW products.
It applies to HTIW bulk wool, blankets, felts, mats, boards, pre-formed shapes and papers, with the exception of products delivered in a wet state.
Further test procedures are in development and will be included once they have been ratified. These include a 3 point bend test for boards, a length weighted fibre diameter measurement technique by Scanning Electron Microscope, shot content measurement (dry and wet methods) and thermal conductivity measurement. There is a shot content method described in BS ISO 10635 and there is a thermal conductivity technique described in ASTM C201.

Diese Europäische Norm definiert Begriffe für die feuerfesten Erzeugnisse und Werkstoffe, die zur Klasse der Hochtemperaturwollen zur Wärmedämmung (HTIW) gehören. Sie legt auch die Klassifizierung von feuerfesten Erzeugnissen zur Wärmedämmung aus HTIW und Verfahren zur Bestimmung der Dicke, der Rohdichte, des Rückfederungsvermögens, der bleibenden linearen Längenänderung, der Zugfestigkeit, des Feuchtegehaltes und des Gehaltes an organischen Bestandteilen von Erzeugnissen aus HTIW fest.
Die Norm gilt für Wolle, Matten, Filze, Vliese, Platten, Formteile und Papier aus HTIW, ausgenommen sind Erzeugnisse, die nass angeliefert werden.
Weitere Prüfverfahren sind in der Entwicklungsphase und werden eingefügt, nachdem sie bestätigt wurden. Sie umfassen eine Drei Punkt Biegeprüfung für Platten, ein längsgewichtetes Verfahren zur Messung des Faserdurchmessers mit dem Rasterelektronenmikroskop, die Bestimmung des Shot Anteils (Trocken und Nassverfahren) und die Bestimmung der Wärmeleitfähigkeit. In ISO 10635 ist ein Verfahren zur Bestimmung des Shot Anteils und in ASTM C 201 ein Verfahren zur Bestimmung der Wärmeleitfähigkeit gegeben.

La présente Norme européenne définit les termes relatifs aux produits et matériaux réfractaires classés dans la catégorie des laines isolantes à haute température (HTIW). Elle établit également la classification des produits réfractaires isolants réalisés à partir de laine isolante à haute température et spécifie des méthodes permettant de déterminer l’épaisseur, la masse volumique apparente, la résilience, la variation linéaire permanente, la résistance à la traction, l’humidité et la teneur en matières organiques des produits HTIW.
Elle s’applique aux produits HTIW, par exemple laine en vrac, nappes, feutres, matelas, panneaux, pièces préformées et papiers, à l’exception des produits livrés à l’état mouillé.
Des modes opératoires d’essai complémentaires sont en cours d’élaboration et y seront incorporés une fois ratifiés. Parmi ces modes opératoires figurent un essai de pliage en 3 points pour cartons, une technique de mesurage par microscope électronique à balayage du diamètre des fibres pondéré par la longueur, le mesurage de la teneur en infibrés (méthodes à l’état sec et mouillé) et le mesurage de la conductivité thermique. La norme ISO 10635 décrit une méthode de détermination de la teneur en infibrés et la technique de détermination de la conductivité thermique est décrite dans la norme ASTM C201.

3.1.7
resilience
ability of HTIW products to spring back after being compressed to 50 % of their initial thickness
3.1.8
tensile strength
apparent maximum tensile stress that the material can withstand
NOTE It is expressed in Pascals (Pa). It is given together with the bulk density determined by subclause 7.2
3.2 Materials and products made from high temperature insulation wool (HTIW)
3.2.1
bulk wool
wool in the state as produced before conversion into other products
NOTE 1 Bulk wool is available as:
a) wool with long fibres with or without finish (lubricant);
b) wool with chopped fibres with variable length due to their application.
NOTE 2 Lubricant is added to the fibres to keep them flexible for further processing the wool products. Typically, the
wool products are thermally treated after production to remove the lubricant.
3.2.2
mat
flexible, non-needled wool without further bonding agent
3.2.3
blanket
flexible, needled mat, free of binders, with nominally determined dimensions
NOTE The mat is processed with barbed felt needles. In consequence, the product becomes denser and stronger.
3.2.4
felt
flexible, non-needled product with further bonding agents
3.2.5
module
blanket formed into thick sections by needling, stacking or folding sheets, compressed to a higher density and
typically supplied with integral anchoring systems
3 3
NOTE Typically, the bulk density of modules is between 160 kg/m and 300 kg/m . Modules can be of a complex
shape.
3.2.6
paper
flexible insulating material formed on a paper-making machine
NOTE Typically, thin shaped HTIW products are kept together by an organic binder (e.g. latex).
3.2.7
board
rigid flat sheet, usually containing inorganic and/or organic binders, produced by a wet process fired or unfired
3.2.8
pre-formed product and shapes
rigid shape with the addition of inorganic and/or organic binders, fired or unfired
NOTE Depending on their production process pre-formed products are subdivided into:
a) vacuum shaped products;
b) mixed products wherein different types of HTIW but also refractory fillers are put together;
c) plastic shaped products;
d) laminated pre-formed products wherein boards, paper or felts are stuck together (on top of each other or
rolled);
e) die-cut products made of blankets, boards or paper.
3.2.9
yarn
bulk HTIW twisted into a continuous thread, with or without the addition of reinforcing filaments
3.2.10
rope
yarn twisted to a rope, with or without reinforcing
NOTE Ropes can be reinforced by glass or metal fibres.
3.2.11
cloth
yarn woven to cloth
3.2.12
mouldable/castable/mastic product
product used for moulding, casting or repairs.
NOTE Mouldable products of HTIW are, for example, added in different proportions to unshaped refractory products
as defined in EN 1402-1.
4 Classification temperature
The product is classified according to the temperature at which the shrinkage obtained by the permanent
linear change in dimensions test, as described in subclause 7.4, does not exceed a given value.
According to the nature of the product, the shrinkage value shall not exceed:
2 % for boards and preformed shapes;
4 % for blankets, felts, mats and papers.
The temperature shall be reported to the nearest 50°C, starting at 850°C and going up to 1 800°C in 50°C
increments.
NOTE Classification temperature does not imply that the product can be used continuously at this temperature. In
practice maximum continuous use temperature for amorphous HTIWs will typically be approximately 100°C to 150°C lower
than the classification temperature. Polycrystalline wool can usually be used up to its classification temperature. The
atmosphere, application (e.g. single use vs. extended) and contact with other substances should all be considered
carefully when selecting the type of high temperature insulation wool for a particular application.
Typical application temperatures are shown in Figure 1.

5 Number of test pieces
The number of items to be tested shall be determined by agreement between the parties. The number of test
pieces per item shall be determined in accordance with Table 5.
6 Preparation of test pieces
When the material to be tested is in a roll form, any compressed material at the extreme ends shall be
excluded. A strip shall be cut perpendicular to the length across the full material width, of sufficient size for the
different tests planned.
From the strip, cut the required number of test pieces of required dimensions, using a template, a sharp knife,
a saw, or other method which will not damage the sample. Avoid excess pressure as this may crush the
produ
