loading equipment may have load reactions far away from the anchor to determine
the base material strength. Note that Hilti provides a complete on-site testing service
with the latest equipment, including a detailed test report an evaluation report.
Destructive loading is also done by applying tension loads. The load level is
selected sufficiently high to result in damage (e.g. in the form of yielding or base
material failure).
However, on-site testing with one or multiple products independent of the reason can
never:
(a) Serve as a substitution of the approval testing for assessing the suitability of
an anchor
(b) Serve as a means to conclude which is a “better” product by comparing loads
from on-site testing of product A vs product B
Although no universal standard exists in Europe for conducting on-site testing, this
type of assessment has been in use as an adjunct to anchor installation quality
control and for the determination of design resistance for many decades. Therefore,
Hilti investigated the existing national and European standards to provide a
consistent and global on-site testing service that is state of the art.
