Clarification of Tolerances on Declared Values for Radiation Properties

April 11, 2009

Clarification of Tolerances on Declared Values for Radiation Properties The harmonised European Standards for the glass products incorporate as essential characteristics the ‘radiometric properties’, i.e. the light transmittance/reflectance and solar energy characteristics. The declared values for these characteristics are given without any explicit tolerances being quoted. The implicit expectation is that the tolerance taken

Presentation of Performance Data for Insulating Glass Units

Presentation of Performance Data for Insulating Glass Units According to European Standards This data sheet describes the method of presenting values of thermal transmittance (U-values) and total solar energy transmittance (g or solar factor) for insulating glass units, in particular those incorporating coated glass. Throughout this data sheet reference is made to European Standards produced

In-situ Measurement and Evaluation of the Colour of Coated Glass used in Facades

April 11, 2007

Code of Practice for in-situ Measurement and Evaluation of the Colour of Coated Glass used in Facades This Code of Practice describes a method for allowing an objective evaluation of the colour of coated glass, as defined in EN 1096-1, when used in facades. It provides a method for measuring colour differences within the same glass
