Glass in building. Determination of thermal transmittance (U value). Guarded hot plate method1 Scope This European Standard specifies a measurement method to determine the thermal transmittance of glazing with flat and parallel surfaces. Structured surfaces, e. g. patterned glass, can be considered to be flat. This European Standard applies to multiple glazing with outer panes which are not transparent to far infrared radiation, which is the case for soda lime silicate glass products, borosilicate glass and glass ceramics. Internal elements

This document specifies safety and performance requirements for the design

The standard was extensively rewritten to bring it up to date with current methodologies

It is an acceptable method for the measurement in the flue gas of different installations

In order to provide the reader with as much information as possible the different ultrasonic technologies hybrids and their applications are discussed in Annex B to provide a comparative overview of the additional capabilities they offer
