Rubber Tensile Stress Strain Test Machine Setup

ASTM D412 and ISO 37 are good tensile test methods to characterize the general stress-strain characteristics of natural rubber, synthetic rubber, silicone rubber, and TPEs (Thermoplastic Elastomers). Both ASTM D412 and ISO 37 specify the test method details to determine tensile stress-strain properties of molded and die cut rubber and elastomers. Rubber and elastomers both feature high extensibility and so extensometers are typically required to accurately measure elongation or stretch while loading is applied. An application engineer can assist in the selection of the best grip and jaw face for rubber tests. Pneumatic air grips with serrated or rubber coated faces are common. A constant gripping force can prevent specimen slippage when specimens elongate. Self-tightening grips, such as roller grips, are also adequate for rubber tests.
