Thermal insulation for buildings - Reflective insulation products - Determination of thermal performance (ISO 22097:2023)

This document describes a set of procedures for using existing standardized CEN or ISO test and calculation methods to determine the thermal performance of reflective insulation products. This document supports and does not replace existing CEN or ISO test methods.
This document applies to any thermal insulation product that derives a proportion of its claimed thermal properties from the presence of one or more reflective or low emissivity surfaces together with any associated airspace(s). It does not replace the existing procedures for the determination of the thermal performance of products already covered by an existing harmonized product standard where the declared value of these products does not specifically include any claims attributable to the emissivity of the facing. It does not, and cannot, give an in-use or design value of thermal performance, but provides standardized information from which these can be determined.

Wärmedämmstoffe für Gebäude - Reflektierende Dämmprodukte - Bestimmung der wärmetechnischen Eigenschaften (ISO 22097:2023)

Dieses Dokument beschreibt eine Reihe von Verfahren zur Anwendung bereits bestehender genormter CEN- oder ISO-Prüf- und Berechnungsverfahren, mit deren Hilfe die wärmetechnischen Eigenschaften von reflektierenden Dämmprodukten bestimmt werden können. Dieses Dokument unterstützt bestehende CEN- bzw. ISO-Prüfverfahren und ist nicht dafür vorgesehen, diese zu ersetzen.
Dieses Dokument ist anwendbar für alle Wärmedämmprodukte, bei denen die beanspruchten wärme-technischen Eigenschaften zu einem beträchtlichen Teil durch das Vorliegen einer oder mehrerer reflektierenden/r oder niedrigemittierenden/r Oberfläche(n) und dem/r zugehörigen Luftraum/räume erreicht werden. Es stellt keinen Ersatz für die bestehenden Verfahren zur Bestimmung der wärmetechnischen Eigenschaften von Produkten dar, die bereits durch eine bestehende harmonisierte Produktnorm abgedeckt sind, und bei denen die Nennwerte dieser Produkte keine spezifischen Ansprüche abdecken, die sich aus dem Emissionsgrad der Deckschicht ergeben. Es enthält weder einsatzbezogene noch Auslegungswerte wärmetechnischer Eigenschaften, und kann solche nicht angeben, stellt jedoch genormte Informationen bereit, anhand derer diese Werte bestimmt werden können.

Isolation thermique des bâtiments - Produits isolants réfléchissants - Détermination de la performance thermique (ISO 22097:2023)

Le présent document décrit un ensemble de modes opératoires pour l’utilisation de méthodes existantes d’essai et de calcul normalisées par le CEN et l’ISO pour déterminer la performance thermique des produits isolants réfléchissants. Le présent document vient à l’appui des méthodes d’essai CEN et ISO existantes, mais il n’est pas destiné à les remplacer.
Le présent document s’applique à tout produit d’isolation thermique dont une partie des propriétés thermiques déclarées est liée à la présence d’une ou plusieurs surfaces réfléchissantes ou à faible émissivité, ainsi qu’à toute lame d’air associée. Il ne remplace pas les modes opératoires existants pour la détermination de la performance thermique des produits déjà couverts par une norme de produit harmonisée existante lorsque la valeur déclarée de ces produits n’inclut pas spécifiquement des propriétés déclarées imputables à l’émissivité des parements. Il ne spécifie, et ne peut spécifier, aucune valeur d’utilisation ou de calcul de la performance thermique, mais il fournit des informations normalisées permettant de déterminer ces valeurs.

Toplotnoizolacijski proizvodi za stavbe - Odsevni izolacijski proizvodi - Ugotavljanje toplotnih lastnosti (ISO 22097:2023)

V tem dokumentu je opisan sklop postopkov za uporabo obstoječih standardiziranih preskusov CEN ali ISO in metod za izračun za ugotavljanje toplotnih lastnosti odsevnih izolacijskih proizvodov. Ta dokument podpira obstoječe metode preskušanja CEN ali ISO in jih ne nadomešča.
Ta dokument se uporablja za katere koli toplotnoizolacijske proizvode, pri katerih del zahtevanih toplotnih lastnosti izhaja iz prisotnosti enega ali več odsevnih površin ali površin nizke emisivnosti skupaj s povezanimi zračnimi prostori. Ne nadomešča obstoječih postopkov za določanje toplotnih lastnosti proizvodov, ki so že zajeti v obstoječem harmoniziranem standardu za proizvod, pri čemer deklarirana vrednost teh proizvodov ne vključuje posebej nobenih določil, ki jih je mogoče pripisati emisivnosti premaza. Ne podaja in ne more podati vrednosti toplotnih lastnosti med uporabo ali konstrukcije vrednosti toplotnih lastnosti, ampak zagotavlja standardizirane informacije, iz katerih jih je mogoče določiti.
