Impact and Crashworthiness
HSL's Impact Testing and Research facilities can fulfil
almost any type of safety-related impact work in areas such as
crashworthiness, secondary damage and regulatory
In addition to an unrivalled range of impact testing facilities
you'll also benefit from our considerable experience and
All samples and prototypes tested in HSL's facilities can be
instrumented with strain gauges, accelerometers, pressure
transducers and load cells as required.
Displacements can be measured directly using high speed video,
line scan cameras and photo-electric sensors. High resolution laser
scans can be provided pre- and post- impact to assist in
understanding any deformations or damage that occurs.
Demonstrating our commitment to quality
assurance, HSL is ISO 9001, ISO 14001 and ISO 18001

For drop tests involving high mass objects, HSL offers a 4 x 4 x
4 metre concrete cube faced with a 50mm steel plate for use as an
'unyielding' drop target.
10m Drop Test
HSL's indoor vertical drop tower has a 10-tonne capacity
hoist and a variable drop height of up to 4 metres.
The rig's vertical height control and drop release system is
accurate to 1mm making it ideal for lower speed impact tests
(impact velocities up to 8m/s) in precisely controlled
The 10m rig can also be used for high strain rate tests on,
for example, webbings used in fall arrest equipment.
25m Drop Test
For faster impact speeds, HSL possesses a drop tower which
offers a drop height variability of up to 25 metres and the
flexibility to accommodate a variety of instrumentation
This drop tower is suitable for testing objects up
to 1 tonne, giving impact energy of up to 240kJ at speeds of up to
Our 265 metre main impact track consists of a single
railway with dual rails (outer and inner gauge)which run down
profiled banks on either side of a valley into a flat impact area
at the valley floor.
The track can be used for impact testing, collision
testing, shock testing, high strain rate testing, wire rope testing
and other compressive or tensile tests.
The main railway impact track has a 4MJ maximum impact
Our 25mm bore gas gun can test projectile masses typically
ranging from 1g to 1kg at speeds up to Mach 1, with the potential
for more depending upon requirements. The gas gun enclosure has two
ports for high speed video that can enable co-efficient of
This facility can be used for test coupons, whilst
a large enclosure also allows us to test components.
Fuel Tank Test Facility
HSL is able to test vehicle fuel tanks for resistance to petrol
fires in accordance with the requirements of UN ECE
