The range offers two types of gas springs – with hydraulic and dynamic damping. Gas springs with
dynamic damping can be installed in any position whereas gas springs with hydraulic dumping should
be installed with piston rod positioned downwards, to make them work properly. Both types have their
respective applications. The quality of the gas springs has also been confi rmed through certifi cation
according to ISO 9001:2000, ISO/TS 16949 and ISO 14000 standards. The strut function is tested and
guaranteed in a temperature range of – 30 °C to +80 °C. Every type of gas spring must withstand
40,000 cycles of expansion and compression at a temperature of 20 °C within the framework of the
fatigue tests as well as hundreds of additional tests at +90 °C and -20 °C. The discharge force must not
fall by more than 12% after the completion of the tests. The protective layer limits the occurrence of
corrosion.
