Thermal performance of windows, doors and shutters - Calculation of thermal transmittance - Part 2: Numerical method for frames (ISO 10077-2:2017)
ISO 10077-2:2017 specifies a method and gives reference input data for the calculation of the thermal transmittance of frame profiles and of the linear thermal transmittance of their junction with glazing or opaque panels.
The method can also be used to evaluate the thermal resistance of shutter profiles and the thermal characteristics of roller shutter boxes and similar components (e.g. blinds).
ISO 10077-2:2017 also gives criteria for the validation of numerical methods used for the calculation.
ISO 10077-2:2017 does not include effects of solar radiation, heat transfer caused by air leakage or three-dimensional heat transfer such as pinpoint metallic connections. Thermal bridge effects between the frame and the building structure are not included.
NOTE Table 1 in the Introduction shows the relative position of ISO 10077-2:2017 within the set of EPB standards in the context of the modular structure as set out in ISO 52000-1.

Performance thermique des fenêtres, portes et fermetures - Calcul du coefficient de transmission thermique - Partie 2 : Méthode numérique pour les encadrements (ISO 10077-2:2017)
L'ISO 10077-2:2017 donne une méthode et des données d'entrée de référence pour le calcul du coefficient de transmission thermique des encadrements et du coefficient de transmission thermique linéique de leurs jonctions avec les vitrages ou les panneaux opaques.
Cette méthode peut également être utilisée pour évaluer la résistance thermique d'encadrements de fermetures et les caractéristiques thermiques de coffres de volet roulant et de composants similaires (par exemple stores).
L'ISO 10077-2:2017 fournit également des critères pour la validation des méthodes numériques utilisées dans ce calcul.
L'ISO 10077-2:2017 ne couvre pas les effets du rayonnement solaire ni le transfert thermique provoqué par des infiltrations d'air ou les transferts thermiques tridimensionnels créés par exemple par des liaisons métalliques ponctuelles. Les effets des ponts thermiques entre les encadrements et la structure du bâtiment ne sont pas pris en compte.
NOTE Le Tableau 1 de l'Introduction indique la position relative de l'ISO 10077-2:2017 dans la série de normes PEB dans le contexte de la structure modulaire définie dans l'ISO 52000‑1.
Toplotne značilnosti oken, vrat in polken - Izračun toplotne prehodnosti - 2. del: Računska metoda za okvirje (ISO 10077-2:2017)
Ta del standarda ISO 10077 določa metodo in podaja referenčne vhodne podatke za izračun toplotne prehodnosti profilov okvirjev in linearne toplotne prehodnosti njihovega spoja z zasteklitvijo ali prosojnimi ploščami. Metodo je mogoče uporabiti tudi za oceno toplotne upornosti profilov polken ter toplotnih značilnosti roletnih škatel in podobnih sestavnih delov (npr. žaluzij). Ta del standarda ISO 10077 določa tudi merila za ovrednotenje računskih metod za izračun. Ta del standarda ISO 10077 ne zajema učinkov sončnega sevanja, prenosa toplote zaradi puščanja zraka ali tridimenzionalnega prenosa toplote, kot so točkaste kovinske povezave. Učinki toplotnih mostov med okvirjem in strukturo stavbe niso zajeti. Področje uporabe predvidoma ne bo spremenjeno. Opravljeni bosta uredniška revizija (nova struktura) v kontekstu mandata M/480 in tehnična revizija obstoječega standarda.
