Thermal insulating products for buildings - In-situ formed dispensed rigid polyurethane (PUR) and polyisocyanurate (PIR) foam products - Part 1: Specification for the rigid foam dispensed system before installation
This European Standard specifies requirements for in-situ formed dispensed rigid polyurethane (PUR) and rigid polyisocyanurate (PIR) foam products when installed into cavity walls.
This Part 1 of this European Standard is a specification for the rigid foam dispensing system before installation.
Part 1 of this European Standard describes the product characteristics and includes procedures for testing, marking and labelling and the rules for evaluation of conformity.
This European Standard does not specify the required levels of all properties that should be achieved by a product to demonstrate fitness for purpose in a particular end-use application. The required levels are to be found in regulations or non-conflicting standards.
This European Standard does not cover factory made rigid polyurethane (PUR) or polyisocyanurate (PIR) foam insulation products or in-situ products intended to be used for the insulation of building equipment and industrial installations.
NOTE Foam products are either called flexible or rigid. The flexible products are used in upholstery and mattresses and are characterised by their ability to deflect, support and recover to their original thickness continually during their in-use phase. Those that are not flexible are termed rigid and do not possess these flexible characteristics. They are mostly used for thermal insulation purposes and vary widely in their compression strength values. Once the cell structure is crushed in a rigid foam, it does not recover its thickness fully. Some of these rigid foams are very low in density with very low compression strengths and are sometimes described “commercially” as “soft foams” or “semi-rigid” foams. This note has been included to clarify that all foams with such descriptions are covered by this standard’s used of the term rigid foam.
Wärmedämmstoffe für das Bauwesen - An der Verwendungsstelle hergestellte Wärmedämmung aus dispensiertem Polyurethan (PUR)- und Polyisocyanurat (PIR)-Hartschaum - Teil 1: Spezifikation für das Schaumsystem vor dem Einbau
Diese Europäische Norm legt Anforderungen an Wärmedämmprodukte aus dispensiertem Poly-urethan(PUR)- und Polyisocyanurat (PIR)-Hartschaum fest, die an der Verwendungsstelle hergestellt und in Hohlwänden eingebaut werden.
Dieser Teil 1 der Europäischen Norm ist eine Spezifikation für das Schaumsystem vor dem Einbau.
Dieser Teil 1 der Europäischen Norm beschreibt die Produktmerkmale und enthält Verfahren für die Prüfung, Kennzeichnung und Etikettierung sowie die Regeln der Konformitätsbewertung.
Diese Europäische Norm legt keine Leistungsstufen für Eigenschaften fest, die ein Produkt erreichen sollten, um für eine bestimmte Endanwendung tauglich zu sein. Die erforderlichen Stufen sind Vorschriften oder nicht entgegenstehenden Normen zu entnehmen.
Diese Europäische Norm gilt weder für werkmäßig hergestellte Wärmedämmstoffe aus Polyurethan (PUR)- oder Polyisocyanurat (PIR)-Schaum noch für Produkte, die für den Einsatz zur Dämmung von technischen Gebäudeausrüstungen und betriebstechnischen Anlagen vorgesehen sind.
ANMERKUNG Schaumstoffprodukte werden in „Weichschaumstoffe“ und „Hartschaumstoffe“ eingeteilt. Weichschaumstoffe werden in Polstermöbeln oder Matratzen verwendet und werden durch ihre Fähigkeit charakterisiert, kontinuierlich während ihrer Nutzungsdauer sich zu verformen, zu stützen und ihre ursprüngliche Dicke wieder anzunehmen. Hartschaumstoffe dagegen weisen diese flexiblen Eigenschaften nicht auf. Sie werden überwiegend als Wärmedämmstoffe eingesetzt und weisen sehr unterschiedliche Druckfestigkeitswerte auf. Wird die Zellstruktur eines Hartschaumstoffes zusammengedrückt, nimmt sie ihre ursprüngliche Dicke nicht wieder an. Einige Hartschaumstoffe besitzen sowohl eine sehr geringe Dichte als auch eine sehr geringe Druckfestigkeit und werden im Handel manchmal als „halbharte“ Hartschaumstoffe bezeichnet. Diese Anmerkung ist eingefügt worden, um klarzustellen, dass alle derart bezeichneten Hartschaumstoffe von dem in dieser Norm verwendeten Begriff „Hartschaum“ abgedeckt sind.

La présente Norme européenne spécifie les exigences relatives aux produits en mousse rigide de polyuréthanne (PUR) ou de polyisocyanurate (PIR) injectée, formés en place, lorsqu'ils sont mis en œuvre dans des murs creux.
Cette Partie 1 de la présente Norme européenne est une spécification du système d'injection de mousse rigide avant mise en œuvre.
Cette Partie 1 de la présente Norme européenne décrit les caractéristiques du produit et contient des modes opératoires d'essai, de marquage et d'étiquetage ainsi que les règles d'évaluation de la conformité.
La présente Norme européenne ne spécifie pas, pour toutes les propriétés, les niveaux exigés que doit atteindre un produit pour démontrer son aptitude à l'emploi dans une application finale particulière. Les niveaux exigés figurent dans des réglementations ou dans des normes non divergentes.
La présente Norme européenne ne couvre pas les produits isolants en mousse rigide de polyuréthanne (PUR) ou de polyisocyanurate (PIR) manufacturés ou formés en place et destinés à être utilisés pour l'isolation des équipements du bâtiment et des installations industrielles.
NOTE Les produits en mousse sont dits flexibles ou rigides. Les produits flexibles sont utilisés dans les garnitures et les matelas et sont caractérisés par leur aptitude à se déformer, supporter et reprendre continuellement leur épaisseur initiale durant leur phase d'utilisation. Les produits qui ne sont pas flexibles sont dits rigides et ne possèdent pas ces caractéristiques flexibles. Ils sont essentiellement utilisés à des fins d'isolation thermique et présentent des valeurs de résistance à la compression très diverses. Lorsque la structure cellulaire d'une mousse rigide est écrasée, elle ne reprend pas totalement son épaisseur initiale. Certaines de ces mousses rigides ont une masse volumique très faible avec une très faible résistance à la compression et sont parfois décrites « commercialement » comme des « mousses souples » ou des « mousses semi-rigides ». Cette note a été incluse pour indiquer clairement que toutes les mousses répondant à ces descriptions sont couvertes par l'utilisation du terme « mousse rigide » dans la présente norme.

4 Requirements
4.1 General The foam properties shall be assessed in accordance with Clause 5. To conform with this standard, foam systems shall meet the requirements of 4.2 and 4.3 as appropriate. NOTE The range of properties exhibited by PUR products is very wide. The same is true for PIR products and these two ranges often overlap. Although not in every case, generally PIR products have a higher upper service temperature and can perform better in reaction to fire tests. In all cases, for both PIR and PUR products, their individual performance claimed by the manufacturer are described by the levels of properties obtained. Accordingly, therefore, all the declaration clauses will be completed using the term PU to include both PUR and PIR products (see 3.1.3). SIST EN 14318-1:2013
Unless otherwise specified by the test method, in all the other test methods involving the measurement of thickness, this shall be carried out using the method given in EN 823. 4.2.2 Thermal resistance and thermal conductivity
Thermal resistance and thermal conductivity shall be based upon measurements carried out in accordance with EN 12667 or EN 12939 for thick products.
The thermal resistance and thermal conductivity (both the initial and the aged values) shall be determined in accordance with Annex A, Annex C and 5.3.2 and the aged values declared by the manufacturer according to the following: The reference mean temperature shall be 10 °C. The measured values shall be expressed with three significant figures. The thermal resistance, RD, shall always be declared. The thermal conductivity, λD, shall be declared wherever this is possible. The declared thermal resistance, RD, and the thermal conductivity, λD, shall be given as limit values representing at least 90 % of the production, determined with a confidence level of 90 %. The value of thermal conductivity, λ90/90, shall be rounded upwards to the nearest 0,001 W/(m·K) and declared as λD in levels with steps of 0,001 W/(m·K). The declared thermal resistance, RD, shall be calculated from the nominal thickness, dN, and the corresponding thermal conductivity, λ90/90 unless measured directly. The value of thermal resistance, R90/90, when calculated from the nominal thickness, dN, and the corresponding thermal conductivity, λ90/90; shall be rounded downwards to the nearest 0,05 m2·K/W, and declared as RD in levels with steps of 0,05 m2·K/W (see Note). An example of the determination of the declared aged values of thermal conductivity and thermal resistance is given in Annex J. NOTE In EN 14318-2, the declaration of the declared installed aged thermal resistance for an installed dispensed rigid PU foam is made by the installer. 4.2.3 Reaction profile and free-rise density
The appropriate values for the reaction profile and free-rise density (either FRC or FRB) for the dispensing foam system shall be declared, having been determined in accordance with the procedures given in Annex E. 4.2.4 Short term water absorption by partial immersion The short term water absorption by partial immersion, Wp, in kg/m2, shall be determined using EN 1609, Method B and shall be declared in kg/m2. No test result shall be higher than the declared value. SIST EN 14318-1:2013
4.3.5 Reaction to fire of products in standardised assemblies simulating end-use applications 4.3.5.1 General The reaction to fire classification taking into account the end-use applications, shall be determined in accordance with Annex I using EN 13501-1 and using data obtained from tests carried out according to procedures in EN ISO 11925-2 and EN 13823 and using test specimens conforming to 4.3.5.2 and mounting and fixing procedures in accordance with 4.3.5.3. NOTE The ignitability procedure using EN ISO 11925-2 in Annex I is identical to the procedure given under H.3.1 and therefore need not be repeated. Accordingly, this clause contains only information relevant to testing carried out according to EN 13823 in Annex I. 4.3.5.2 Test specimens for the EN 13823 test Prepare five long and five short wing specimens in accordance with I.3.2.1. 4.3.5.3 Mounting and fixing procedure 4.3.5.3.1 EN 13823 Test specimens prepared in accordance with 4.3.5.2 shall be mounted so that the inner face of the test specimen which is typical of the end use application is in contact with the flame source. Only the corner joint shall be incorporated and this shall be protected by a steel angle bracket. In all other respects, the products shall be mounted as specified in EN 13823:2010, 5.2.2. 4.3.6 Continuous glowing combustion Where subject to regulations, the manufacturer shall declare the continuous glowing combustion of the product. In the absence of a European test method, the compliance with the requirement shall be made on the basis of any existing national test method. NOTE A European test method is under development and the standard will be amended when this is available. 4.3.7 Dimensional stability under specified temperature and humidity conditions Dimensional stability under specified temperature and humidity conditions shall be determined in accordance with EN 1604. The tests, each on different sets of specimens, shall be carried out for (48 ± 1) h at both (-20 ± 3) °C and at (70 ± 2) °C and a relative humidity of (90 ± 5) %. The relative changes in length, ∆0I, with ∆0b and thickness ∆0d, shall not exceed the values given in Table 3 for the labelled level. SIST EN 14318-1:2013
