Glass construction Classification according to EN16612:2019 and EN16613:2019 - Simplified method

This document provides the technical data for Trosifol® PVB and SentryGlas® ionoplast interlayers which is required in the two following European codes: EN16612:2019 and EN16613:2019 The data provided allows the calculation of laminated glass stress and deformation according to the simplified method as described in Annex D of EN16612:2019. This method allows to calculate the equivalent thickness of a specific laminated glass make-up using a factor ω which characterizes the coupling characteristics of the interlayer. This factor can vary between 0 (no coupling) and 1 (full coupling). Since the coupling function of the interlayer is time and temperature dependent, the method also defines 12 load cases for which the ω factors are shown
