How to Perform a Tensile Strength Test According to ASTM D412
ASTM D412 is the most common standard for determining the tensile properties of vulcanized (thermoset) rubber and thermoplastic elastomers. Compounds in this family are used to create a vast array of consumer goods such as tires, footballs, and rubber bands.
What does it Measure?
ASTM D412 measures the elasticity of a material while under tensile strain, as well as its behavior after testing when the material is no longer being stressed. ASTM D412 is conducted on a universal testing machine (also called a tensile testing machine) at a rate of 500 ± 50 mm/min until the specimen fails. Though ASTM D412 measures many different tensile properties, the following are the most common:
-
Tensile strength – the maximum tensile stress applied in stretching a specimen to rupture.
-
Tensile stress at a given elongation – the stress required to stretch the uniform cross-section of a test specimen to a given elongation.
-
Ultimate elongation – the elongation at which rupture occurs in the application of continued tensile stress.
-
Tensile set – the extension remaining after a specimen has been stretched and allowed to retract in a specified manner, expressed as a percentage of the original length.
When your rubber or elastomer components need reliable performance validation, GESTER delivers precise, reliable ASTM D412 testing services to help ensure your products meet quality and regulatory requirements.
