CI LUD® - Performance Testing
are frequently subjected to fullscale testing to demonstrate
that they meet specifications. Typical is the rigorous
HITEC test regime described here. The robust nature of
the CI LUD® is clearly shown in the results of
this and other test programs. Certified independent test
certificates are available.
CI and HITEC
The Highway Innovative
Technology Evaluation Centre (HITEC) is an organisation
created by the American Society of Civil Engineers (ASCE) to
bring together diverse groups within the civil engineering
community to 'facilitate, integrate and coordinate' common
solutions to complex research challenges facing the civil
In order to evaluate the CI Lock Up Device HITEC formed a
panel of seismic experts at Federal and State level together
with representatives of seismic research organisations and
internationally renowned design consultants.
The panel formulated an evaluation programme which comprised
a testing schedule for three separate Lock Up Devices and a
series of trial installations within the USA.
The intent of the programme being to demonstrate that the
Lock Up Devices will perform as required during their
service life and will adequately cope with the extremes of
temperature (-40°C to +50°C) that can be anticipated in the
The evaluation programme was successfully completed and the
results are presented in a separate HITEC report is available.
