Hegewald & Peschke Creep Testing Devices
Long-term creep testing under constant weight loading
The Creep Testing Devices from Hegewald & Peschke load cardboard, corrugated cardboard, leather and textile samples with constant weights over long periods while the deformation is recorded, for compression, bending and tensile tests.

Overview
Deformation under long-term constant load
Hegewald & Peschke creep testing devices evaluate material deformation under long-term loading. The systems apply a constant load using weights while the sample stays loaded for a long time and its deformation is recorded.
Cardboard creep devices can be used inside a climate chamber to study the effect of humidity and temperature changes, or as tabletop units outside the chamber, depending on configuration. Digital displacement transducers record the deformation path and pass the data to evaluation software.
The tensile creep loading unit for textile and leather samples uses mechanically decoupled stations, so a breaking sample does not cause vibration at the other stations.

Benefits
Why test creep
Long-term stability. Shows how materials behave under constant load over time.
Storage conditions. Simulates real storage and warehousing loads on cardboard.
Climate effects. Shows the effect of humidity and temperature on cardboard performance.
Several samples. Multiple test positions improve testing efficiency.
Simple loading. Weight loading gives a simple, constant load application.
Undisturbed stations. Decoupled stations keep a breaking sample from affecting the others.
