Die Berechnung umfasst
 unterschiedliche Verglasungsarten, z. B. aus Glas oder Kunststoff, einfache und mehrfache
Verglasungen, Verglasungen mit oder ohne Beschichtungen mit niedrigem Emissionsgrad sowie
Verglasungen mit einem Zwischenraum, der mit Luft oder anderen Gasen gefüllt ist;
 Rahmen (aus einem beliebigen Material), mit oder ohne wärmetechnische Trennung;
 verschiedene Arten von opaken Paneelen, die mit Metall, Glas, Keramik oder einem anderen Material
verkleidet sind.
Die Berechnung berücksichtigt den Einfluss von Wärmebrücken am Falz oder an der Fuge zwischen der
verglasten Fläche, dem Rahmen und dem Paneel.
Folgende Faktoren werden in der Berechnung nicht berücksichtigt:
 Einflüsse aus der Sonneneinstrahlung;
 Wärmeübertragung durch Luftdurchlässigkeit;
 Tauverhalten;
 Einfluss von Abschlüssen;
 zusätzliche Wärmeübertragung an den Ecken und Kanten der Vorhangfassade;
 Verbindungen mit das Tragwerk und die dazu verwendeten Verbindungsmittel;
 Vorhangfassaden mit eingebauter Heizung.

Ta mednarodni standard določa metodo za izračun toplotne prehodnosti obešenih fasad iz steklenih in/ali prosojnih plošč, nameščenih v okvirje ali povezanih z okvirji. Izračun vključuje: – različne vrste zasteklitve, npr. iz stekla ali plastike; enojna ali večkratna zasteklitev; z nanosom ali brez nanosa nizke emisivnosti; z vmesnimi prostori, napolnjenimi z zrakom ali drugimi plini; – okvirje (iz katerega koli materiala) s toplotnimi prekinitvami ali brez; – različne vrste prosojnih plošč, prevlečenih s kovino, steklom, keramiko ali drugimi materiali. Toplotni mostovi na znižanju ali stiku med zastekljenim območjem, območjem okvirja in območjem plošče so vključeni v izračun. Izračun ne vključuje: – učinkov sončnega sevanja; – prenosa toplote zaradi puščanja zraka; – izračuna kondenzacije; – učinkov polken; – dodatnega prenosa toplote v kotih in na robovih zidov za zavese; – povezav z glavno stavbno strukturo ali skozi pritrdilne spoje; – sistemov zidov za zavese z vgrajenim gretjem.

Thermal performance of curtain walling - Calculation of thermal transmittance (ISO 12631:2017)
SIST EN ISO 12631:2017

ISO 12631:2017 specifies a method for calculating the thermal transmittance of curtain walls consisting of glazed and/or opaque panels fitted in, or connected to, frames.
The calculation includes:
-      different types of glazing, e.g. glass or plastic; single or multiple glazing; with or without low emissivity coating; with cavities filled with air or other gases;
-      frames (of any material) with or without thermal breaks;
-      different types of opaque panels clad with metal, glass, ceramics or any other material.
Thermal bridge effects at the rebate or connection between the glazed area, the frame area and the panel area are included in the calculation.
The calculation does not include:
-      effects of solar radiation;
-      heat transfer caused by air leakage;
-      calculation of condensation;
-      effect of shutters;
-      additional heat transfer at the corners and edges of the curtain walling;
-      connections to the main building structure nor through fixing lugs;
-      curtain wall systems with integrated heating.
NOTE       Table 1 in the Introduction shows the relative position of ISO 12631:2017 within the set of EPB standards in the context of the modular structure as set out in ISO 52000-1.

This Standard establishes the principles and criteria to be complied with for the determination of the laboratory steady-state heat transfer properties of masonry walls in a hot box by means of a heat flow meter mounted on one face of the masonry wall to be tested (i.e. the test specimen). It describes the apparatus, measurement technique and necessary data reporting. It does not, however, specify a particular apparatus design since requirements vary particularly in terms of size, and also to a lesser extent in terms of operating conditions.

Gas cylinders - Cylinder valves with integrated pressure regulators - Specification and type testing (ISO 22435:2024)
kSIST FprEN ISO 22435:2024

This document specifies design, type test methods, marking and instruction requirements for cylinder valves with integrated pressure regulators (VIPRs) intended to be fitted to gas cylinders, pressure drums or tubes or used as a main valve for bundles of cylinders that convey compressed, liquefied or dissolved gases.
These are requirements for VIPRs that are in addition to those given in the relevant closure standard, for example, in ISO 10297 for cylinder valves, in ISO 17871 for quick-release cylinder valves, in ISO 17879 for self-closing cylinder valves or in ISO 23826 for ball valves. For ISO 17871, these requirements are only applicable to quick-release cylinder valves types B, C, D and E.
NOTE 1        If the pressure regulating system of a VIPR is acting as the primary valve operating mechanism, it is covered by the relevant closure standard, e.g. ISO 10297, ISO 17871, ISO 17879 and ISO 23826. This also includes designs where closure of the primary valve operating mechanism of a VIPR is obtained by closing the seat of the pressure regulating system.
NOTE 2        If the primary valve operating mechanism of a VIPR is located at the low-pressure side of the pressure regulating system, it is covered by the relevant closure standard, e.g. ISO 10297, ISO 17871, ISO 17879 and ISO 23826.
NOTE 3        The term “pressure receptacle” is used within this document to cover instances where no differentiation is necessary between gas cylinders, bundles of cylinders, pressure drums and tubes.
This document does not apply to VIPRs for
a)       medical applications (see ISO 10524-3);
b)       liquefied petroleum gas (LPG);
c)        cryogenic applications.
NOTE 4        Additional requirements for a VIPR with a residual pressure device (RPD) are specified in ISO 15996.
NOTE 5        Additional requirements for pressure relief valves can exist in international/regional regulations/ standards.

The purpose of this deliverable is to specify and describe choreographies for exchanging an electronic product catalogue (“catalogues”) as part of the business processes in the pre-award and post-award area, so that catalogues can serve as a basis for placing orders as well as evaluating tenders. The key aspects covered by this choreography specification are:
-   processes for submitting catalogues from the selling to the buying side;
-   processes for submitting catalogue-related data as part of a tendering process;
-   processes integrating sell-side procurement systems.
This document does not apply to the transactions used in the specified choreographies. These transactions are specified in EN 17015 2. The relationship between the choreographies and the transaction is described in Clause 8.
The identifier of this choreographies document is EN 17015 1:2024.
How to claim compliance to this choreography is specified in 6.2.3.
