Thermal insulating products for building equipment and industrial installations - In-situ formed sprayed rigid polyurethane (PUR) and polyisocyanurate foam (PIR) products - Part 1: Specification for the rigid foam spray system before installation
This European Standard specifies requirements for in-situ formed sprayed rigid polyurethane (PUR) and polyisocyanurate (PIR) foam products for the insulation of building equipment and industrial installations, for example storage vessels, pipes and ducts used for the supply of fuels, oil, other liquids, hot and cold water, air and other gases.
Depending on the type of foam products complying with this standard, they may have service temperature ranges which lie within the limits of ± 200 °C.
This Part 1 of this European Standard is a specification for the rigid foam system before installation.
Part 1 of this European Standard describes the product characteristics and it 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 or polyisocyanurate foam insulation products or in-situ products intended to be used for the insulation of buildings.
This standard does not specify performance requirements for direct airborne sound insulation and acoustic absorption applications.
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 die technische Gebäudeausrüstung und für betriebstechnische Anlagen in der Industrie - An der Verwendungsstelle hergestellte Wärmedämmung aus Polyurethan (PUR)- und Polyisocyanurat (PIR)-Spritzschaum - Teil 1: Spezifikation für das Schaumsystem vor dem Einbau
Diese Europäische Norm legt Anforderungen an Wärmedämmprodukte aus Polyurethan (PUR)- und Polyisocyanurat (PIR)-Spritzschaum fest, die an der Verwendungsstelle hergestellt und für die Dämmung von technischen Gebäudeausrüstungen und betriebstechnischen Anlagen in der Industrie verwendet werden, z. B. für Vorratskessel, Rohre und Leitungen für die Zufuhr von Brennstoff, Öl, sonstigen Flüssigkeiten, Warm- und Kaltwasser, Luft und sonstigen Gasen.
Abhängig vom einzelnen Produkt können die Schaumprodukte nach dieser Norm einen Anwendungstemperaturbereich haben, die kleiner als der Bereich −200 °C bis + 200 °C ist.
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 werden sollte, 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 an der Verwendungsstelle hergestellte Produkte, die für den Einsatz bei der Dämmung von Gebäuden vorgesehen sind.
Dieses Dokument enthält keine Leistungsanforderungen in Bezug auf den Einsatz zur Luftschalldämmung oder zur Schallabsorption.
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.
Produits d'isolation thermiques destinés aux applications du bâtiment et aux installations industrielles - Produits en mousse rigide de polyuréthanne (PUR) et de polyisocyanurate (PIR) projetée, formés en place - Partie 1: Spécifications relatives aux systèmes de projection du polyuréthanne et du polyisocyanurate avant mise en oeuvre
La présente Norme européenne spécifie les exigences relatives aux produits en mousse rigide de polyuréthanne (PUR) et de polyisocyanurate (PIR) projetée, formés en place, destinés à l’isolation de l’équipement des bâtiments et des installations industrielles, par exemple cuves de stockage, tuyauteries et conduits utilisés pour la distribution de combustibles, d’huile, d’autres liquides, d’eau chaude et froide, d’air et d’autres gaz.
Selon leur type, les produits en mousse conformes à la présente norme peuvent avoir une plage de température de service comprise dans les limites de ± 200 °C.
La présente Partie 1 de la norme est une spécification du système de mousse rigide avant mise en œuvre.
La 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 requis figurent dans les réglementations ou normes non contradictoires.
La présente Norme européenne ne couvre pas les produits d’isolation en mousse rigide de polyuréthanne ou de polyisocyanurate manufacturés ou les produits formés en place destinés à être utilisés pour l’isolation des bâtiments.
La présente norme ne spécifie pas d’exigences de performance pour les applications d’isolation au bruit aérien direct et d’absorption acoustique.
NOTE Les produits en mousse sont appelés soit flexibles, soit rigides. Les produits flexibles sont utilisés comme revêtement et matelas, et se caractérisent par leur capacité à supporter les déflexions et retrouver leur épaisseur d’origine de façon répétée pendant leur période d’utilisation. Les produits qui ne disposent pas de ces propriétés flexibles sont appelés rigides. Ils sont principalement destinés à l’isolation thermique et leur valeur de résistance à la compression varie grandement. Dès lors que la structure d’une mousse rigide est compressée, elle ne retrouve pas totalement son épaisseur d’origine. Certaines de ces mousses rigides ont une très faible densité et une résistance à la compression modérée, elles sont parfois décrites « commercialement » comme « mousses légères » ou « mousses semi-rigides ». La présente note vise à clarifier le fait que toutes les mousses ainsi identifiées sont couvertes par l’utilisation du terme mousse rigide dans la présente norme.
Toplotnoizolacijski proizvodi za opremo stavb in industrijske inštalacije - Proizvodi iz trde poliuretanske pene (PUR) in poliizocianuratne pene (PIR), oblikovani na mestu vgradnje - 1. del: Specifikacija penastega sistema pred vgradnjo
Ta evropski standard določa zahteve za proizvode iz brizgane trdne poliuretanske pene (PUR) in poliizocianuratne pene (PIR) za izolacijo opreme stavb in industrijskih inštalacij, na primer posode za shranjevanje, cevi in vodov, uporabljenih za oskrbo z gorivi, oljem, drugimi tekočinami, vročo in hladno vodo, zrakom in drugimi plini. Glede na vrsto izdelkov iz pene, ki so v skladu s tem standardom, imajo lahko razpon servisne temperature znotraj ±200 °C. Ta 1. del tega evropskega standarda je specifikacija za trdni penasti sitem pred vgradnjo. 1. del tega evropskega standarda opisuje lastnosti proizvoda in vključuje postopke za preskušanje, označevanje in etiketiranje ter pravila za ocenjevanje skladnosti. Ta evropski standard ne določa zahtevanih ravni vseh lastnosti, ki jih mora proizvod doseči, da se dokaže njegova primernost namenu za posamezno vrsto končne uporabe. Zahtevane ravni so določene v uredbah ali standardih, ki niso v nasprotju s tem standardom. Ta evropski standard ne zajema izolacijskih proizvodov iz trde poliuretanske pene in poliizocianuratne pene ali proizvodov, izdelanih na kraju samem, namenjenih za izolacijo stavb. Ta standard ne določa zahtev za delovanje neposredne izolacije pred zvokom v zraku in aplikacij za absorpcijo zvoka. OPOMBA: Penasti izdelki so fleksibilni ali trdni. Fleksibilni izdelki se uporabljajo pri tapetništvu in žimnicah, zanje pa je značilna zmožnost neprekinjenega odvračanja, podpiranja in obnavljanja svoje originalne debeline med fazo neuporabe. Nefleksibilni izdelki veljajo za trdne in nimajo teh fleksibilnih lastnosti. Večinoma se uporabljajo za namene toplotne izolacije in se močno razlikujejo v vrednostih moči stiskanja. Ko je celična zgradba v trdni peni porušena, ni možno več v celoti obnoviti njene debeline. Nekatere od teh pen imajo zelo nizko gostoto z zelo nizkimi močmi stiskanja in so včasih na trgu opisane kot »mehke« ali »srednje trde« pene. Ta opomba je vključena kot pojasnilo, da ta standard opisuje vse pene s takšnim opisom, ki se nanaša na trdne pene.

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. Though 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 is 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 14320-1:2013
The thermal conductivity values shall be determined by the manufacturer and verified in accordance with EN ISO 13787 and Annex C of this product standard. They shall be declared by the manufacturer according to measuring standards mentioned above, covering the product service temperature range. The following conditions apply: the measured values shall be expressed with three significant figures; the declared thermal conductivity curve shall be given as a limit curve, defined in EN ISO 13787 and measured using the details given in 5.3.2; the value of the declared thermal conductivity, D, shall be rounded upwards to the nearest 0,001 W/(m·K); the lowest reference test temperature required is -170 °C. The declared equation/limit curve is the “declared reference” with three significant figures, that is to 0,000 1 W/(m·K) for
values below 0,1 W/(m·K) and in 0,001 W/(m·K) for
values above 0,1 W/(m·K). This shall be used as a reference for the verification of the declaration. When thermal conductivity is declared as a table derived from the curve, it shall be rounded upwards to the next 0,001 W/(m.K) for the full range of the thermal conductivities. NOTE The declaration of declared installed thickness for an installed sprayed rigid PU foam is described in

No test result shall be higher than the declared value. 4.3.4 Compressive stress or compressive strength Compressive stress at 10 % deformation σ10 or the compressive strength, σm} shall be determined in accordance with EN 826. No test result for either the compressive stress at 10 % deformation, σ10 or the compressive strength, σm} whichever is the smaller, shall be lower than the value, given in Table 2, for the declared level. SIST EN 14320-1:2013
For PUR/PIR products the effects of traffic shall be assessed by means of determination of the compressive stress or compressive strength in accordance with EN 826. 4.3.5 Dangerous substances National regulations on dangerous substances may require verification and declaration on release, and sometimes content, when construction products covered by this standard are placed on those markets. In the absence of European harmonised test methods, verification and declaration on release/content should be done taking into account national provisions in the place of use. NOTE An informative database covering European and national provisions on dangerous substances is available at the Construction web site on EUROPA accessed through: http://ec.europa.eu/enterprise/construction/cpd-ds/ 4.3.6 Maximum service temperature The maximum service temperature, TU, in °C, shall be taken as either the value determined using the method given in EN 14706 or the value declared by the manufacturer, whichever is the lower. 4.3.7 Minimum service temperature The minimum service temperature, TL, in °C, shall be taken as either the value determined using the method given in 4.3.3 of EN 14308:2009 or the value declared by the manufacturer, whichever is the higher. 4.3.8 Rate of release of corrosive substances The amount of water soluble chloride shall be determined in accordance with EN 13468 (leaching time of
0,5 h at (100 ± 1) °C), with the soluble chloride content, w, given as the value in ppm of chloride ion per kg. 4.3.9 Substrate adhesion strength perpendicular to faces The substrate adhesion strength perpendicular to faces, shall be determined in accordance with the procedure given in Annex E.

Neither shall they be used for the other properties unless otherwise specified in the test standards. In case of dispute, the test specimens shall be stored at (23 ± 2) °C and (50 ± 5) % relative humidity for at least 16 h prior to testing. 5.3 Testing 5.3.1 General Table 5 gives the dimensions of the test specimens, the minimum number of test specimens required to get one test result and any specific conditions which are necessary. 5.3.2 Thermal conductivity Thermal conductivity shall be determined in accordance with EN 12667 or EN 12939 for thick products.
The thermal conductivity shall be determined for the full service temperature range of the product. For factory production control and initial type testing requirements, see Annex A. For the construction of the thermal conductivity curve from the minimum to the maximum service temperature, the test specimen shall be aged and conditioned in accordance with C.4.2 or C.5.2.
The aged thermal conductivity, λD, shall be determined using an aged product in accordance with EN 12667 or EN 12939 for thick products. Accordingly, the aged thermal conductivity shall be determined under the following conditions: A curve of thermal conductivity against temperature shall be constructed, similar to those derived by the EN ISO 13787 procedure, for the claimed service temperature range (3.1.13) appropriate to the product. This is best achieved by using measurements at a minimum of five temperatures distributed throughout this claimed service temperature range as follows. One should be taken close to the maximum service temperature limit. A second one shall be taken close to the minimum service temperature limit. A third one shall be measured at +10 °C and a fourth one close to -30 °C. At least one further additional SIST EN 14320-1:2013
