Glass in building - Spectrophotometric characteristics of glass products - Validation procedure for calculation tool.
This standard provides a procedure to validate a calculation tool of spectrophotometric and thermal characteristics of the glass products following EN 410 or EN 673. It provides also the methodology to correctly use measured data in the calculation tool.
The following characteristics are included in the scope of this standard:
- light transmittance (tv)
- light reflectance - both sides (rv, r'v)
- solar direct transmittance (te)
- solar direct reflectance – both sides (re, r'e)
- total solar energy transmittance (solar factor or g value) (g)
- thermal transmittance (U value) in the vertical position
The following characteristics are excluded from the scope of this standard:
- UV transmittance (tuv)
- shading coefficient (SC)
- general colour rendering index (Ra)
- thermal transmittance (U value) at angles other than vertical
Glas im Bauwesen - Spektralphotometrische Eigenschaften von Glasprodukten - Validierungsverfahren für das Berechnungstool
Dieses Dokument liefert ein Verfahren zur Validierung eines Berechnungstools für spektralphotometrische und thermische Eigenschaften von Glaserzeugnissen nach EN410 oder EN673. Es liefert zudem die Methodik für eine korrekte Verwendung von Messdaten im Berechnungstool.
Die folgenden Eigenschaften liegen im Anwendungsbereich dieses Dokuments:
- Lichttransmissionsgrad (tv);
- Lichtreflexionsgrad–beidseitig (rv, r’v);
- direkter Strahlungstransmissionsgrad (te);
- direkter Strahlungsreflexionsgrad–beidseitig (re, r’e);
- Gesamtenergiedurchlassgrad (Sonnenfaktor oder g-Wert) (g);
- Wärmedurchgangskoeffizient (U-Wert) in der aufrechten Position.
Die folgenden Eigenschaften liegen außerhalb des Anwendungsbereiches dieses Dokuments:
- UV-Transmissionsgrad (tuv);
- mittlerer Durchlassfaktor (SC, en: shading coefficient);
- allgemeiner Farbwiedergabeindex (Ra);
- Wärmedurchgangskoeffizient (U-Wert) in anderen Winkeln als der aufrechten Position.
