Thermal insulating products for building equipment and industrial installations - Determination of water vapour transmission properties of preformed pipe insulation
This European Standard specifies the equipment and procedure for determining the water vapour transmission properties in the steady state under specified test conditions for test specimens of preformed pipe insulation. It is applicable to thermal insulating products. It is intended to be used for homogeneous materials (see NOTE) and for products which may have integral skins or adhered facings of some different material.
Wärmedämmstoffe für die Haustechnik und für betriebstechnische Anlagen - Bestimmung der Wasserdampfdurchlässigkeit von vorgeformten Rohrdämmstoffen
Diese Europäische Norm legt Prüfeinrichtungen und Verfahren zur Bestimmung der Wasserdampfdurchlässigkeits-Eigenschaften von Probekörpern aus vorgeformten Rohrdämmstoffen im stationären Zustand unter definierten Prüfbedingungen fest. Sie gilt für Wärmedämmstoffe. Die Norm ist anwendbar bei homogenen Dämmstoffen (siehe ANMERKUNG) und bei Produkten, die als festen Bestandteil bestimmte Oberflächenschichten oder Kaschierungen aus anderen Werkstoffen enthalten können. ANMERKUNG Ein Dämmstoff wird als homogen hinsichtlich seiner Massenverteilung angesehen, wenn seine Dichte überall etwa gleich ist, das heißt, wenn die gemessenen Werte nahe beim Mittelwert seiner Rohdichte liegen. Die Wasserdampf-Diffusionsstromdichte und der Wasserdampf-Diffusionsdurchlasskoeffizient sind abhängig von der Dicke des geprüften Probekörpers bzw. des Produkts. Für homogene Produkte ist der Wasserdampf-Diffusionsleitkoeffizient eine Stoffeigenschaft. Ist die Rohrschale aus einem ebenen Produkt herausgeschnitten worden, können die Wasserdampfdurchlässigkeits-Eigenschaften aus Prüfungen bestimmt werden, die nach EN 12086 an dem ebenen Produkt mit ähnlichen Eigenschaften durchgeführt werden.
Produits isolants thermiques pour l'équipement du bâtiment et les installations industrielles - Détermination des propriétés de transmission de la vapeur d'eau des coquilles isolantes préformées
La présente Norme européenne spécifie les équipements nécessaires et les procédures à suivre pour
déterminer à l'équilibre et dans des conditions d'essai spécifiques, les propriétés de transmission de la vapeur
d'eau d’éprouvettes constituées de coquilles isolantes préformées. Elle s'applique aux produits isolants
thermiques.
Elle est destinée aux matériaux homogènes (voir NOTE) et aux produits qui pourraient posséder des
revêtements intégrés ou des parements collés faits d'un autre matériau.
NOTE Un matériau est estimé homogène quant à sa distribution massique si sa densité est à peu près la même
partout, c'est-à-dire si les valeurs mesurées de la densité sont proches de sa densité moyenne.
Le taux de transmission de la vapeur d'eau et le degré de perméance dépendent de l'épaisseur de
l’éprouvette (c'est-à-dire du produit) soumise à l'essai. Dans le cas des produits homogènes, la perméabilité à
la vapeur d'eau est une propriété du matériau.
Si la coquille isolante est découpée dans un produit plat, les propriétés de transmission de la vapeur d'eau
peuvent être déterminées à partir d'essais effectués selon l'EN 12086 sur le produit plat possédant des
propriétés semblables.

EN 13469:2012 (E) 3 Foreword This document (EN 13469:2012) has been prepared by Technical Committee CEN/TC 88 “Thermal insulating materials and products”, the secretariat of which is held by DIN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by April 2013, and conflicting national standards shall be withdrawn at the latest by April 2013. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 13469:2001. The following main technical changes have been implemented in this new edition of EN 13469: a) the content of Annex A "Correction for air pressure variations during test" has been included in the main part of the standard and the annex has been deleted; b) the document has been editorially updated. This European Standard is one of a series of standards which specify test methods for determining dimensions and properties of thermal insulating materials and products. It supports a series of product standards for thermal insulating materials and products which derive from the Council Directive of 21 December 1988 on the approximation of laws, regulations and administrative provisions of the Member States relating to construction products (Directive 89/106/EEC) through the consideration of the essential requirements. This European Standard has been prepared for products used to insulate building equipment and industrial installations, but it may also be applied to products used in other areas. According to the CEN/CENELEC Internal Regulations, the national standards organisations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom.

EN 13469:2012 (E) 4 1 Scope This European Standard specifies the equipment and procedure for determining the water vapour transmission properties in the steady state under specified test conditions for test specimens of preformed pipe insulation. It is applicable to thermal insulating products. It is intended to be used for homogeneous materials (see NOTE) and for products which may have integral skins or adhered facings of some different material. NOTE A material is considered to be homogeneous in terms of mass distribution if its density is approximately the same throughout, i.e. if the measured density values are close to its mean density. The water vapour transmission rate and permeance values are specific to the test specimen (i.e. the product) thickness tested. For homogeneous products, the water vapour permeability is a property of the material. If the pipe insulation is cut from a flat product, then the water vapour transmission properties can be obtained from tests carried out on the flat product with similar properties in accordance with EN 12086. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
