Thermal conductivity measurements can be divided into two groups: steady state and transient state testing methods. Steady state methods also includes guarded hot-plate (GHP) method and Heat-Flow Meter (HFM), while a typical transient method is Laser/Xenon Flash (LFA/XFA) method.

Wet Tensile Tests
Wet tensile strength of a sample is important to evaluate the mechanic performances subjected to moisture and stress during processing or use. It is particularly useful for measuring paper and other materials which are easily damaged by handling when wet.
