Glass in building. Spectrophotometric characteristics of glass products. Validation procedure for calculation tool.
Soveltamisala
Suomenkielistä soveltamisalaa ei ole saatavissa.
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
