依據 ASTM-D5470 標準, 三種樣品模式自動量測：
I. 高黏度液體Viscous liquids、
II. 黏彈性固體Viscoelastic solids、
III. 彈性固體Elastic solids
ASTM D5470 is useful for measuring the thermal impedance of the following material types.
Type I—Viscous liquids that exhibit unlimited deformation when a stress is applied. These include liquid compounds such as greases, pastes, and phase change materials. These materials exhibit no evidence of elastic behavior or the tendency to return to initial shape after deflection stresses are removed.
Type II—Viscoelastic solids where stresses of deformation are ultimately balanced by internal material stresses thus limiting further deformation. Examples include gels, soft, and hard rubbers. These materials exhibit linear elastic properties with significant deflection relative to material thickness.
Type III—Elastic solids which exhibit negligible deflection. Examples include ceramics, metals, and some types of plastics.
