Hilti anchors with epoxy8/22/2023 This new EAD follows a similar assessment approach as the 50-year working life EAD but typically with extended test durations and test cycles. In October 2018, 'EAD 33-2077-06.01 Bonded fasteners for use in concrete with a service life of 100-years' was provisionally completed in Europe by EOTA. In the case of 50-year working life ETA documents, these are based on assessment to the European Assessment Document 'EAD-3301- Bonded anchors for use in concrete' which includes assessment such as extrapolation of sustained load data to 50- years. When we look at the design life of a chemical anchor, for any duration, we must consider load resistance performance, displacement and durability.
