Tensile Strength Testing

Tensile tests measure the tensile force required to stretch, yield, and fracture a material and the extent to which the material elongates to the yield or failure point.

Approaches

Tensile testing is often used as a quality control check of the material or parts. It is also used frequently as input during the design phase of a material or molded product. Tensile tests are often used to measure the loss in mechanical strength as a function of use, accelerated aging, or chemical exposure. ASTM Standards:

ASTM D882
ASTM D638
ASTM D412

Sample Considerations

There are unique test protocols used for tensile testing of:

Films
Plastics
Rubbery materials
Metals

Standard specimens or molded products can also be tested.

Experience

We frequently conduct tensile testing suppliers or consumers as a means of quality control.

Products we’ve tested:

Slats for lawn furniture
Multi-layer packaging films
Polymer rivets used in bowling machines
Plastic conduit for electrical cable installations
Strength of orthopedic anchors in bone and bone simulants
