One method of Ultimate Elongation ASTM-D4325 1000% determining a rubber material consistency is by measuring the Operating Temperature 90°C (194°F) modulus of the material. The modulus of a material is the stress Emergency Operating Temperature 130°C (266°F) required to elongate the material to a given elongation.
