Dedicated Rubber Testing Accessories
Self-Tightening Roller Grips (STR1)
25 mm to 50 mm self-tightening roller grips designed specifically for rubber and elastomer specimens. Prevents slippage and eliminates premature grip-area failure for accurate tensile and peel testing.
Long Travel Extensometer (DE-A3)
Contact extensometer for rubber and other elastomers with an 850 mm travel range and 0.01 mm resolution. Designed for high-elongation measurements where specimens stretch far beyond typical gauge lengths.

Frequently Asked Questions
Common questions about rubber and elastomer materials testing
ASTM D412 is the American standard for tensile testing of vulcanized rubber and thermoplastic elastomers, while ISO 37 is the international equivalent. Both use dumbbell-shaped specimens but differ in specimen dimensions, dumbbell types, and some calculation methods. Both measure tensile strength, elongation at break, and stress at defined elongation.
Self-tightening or pneumatic rubber grips are recommended for elastomer testing. These grips distribute the clamping load over the full width of the specimen tab, preventing premature failure in the grip area — a common problem with standard wedge grips on soft, high-elongation materials.
Non-contact video extensometers are the most accurate method for rubber specimens, which can stretch beyond 500–1000% before breaking. They track optical gauge marks on the specimen without contact, eliminating grip-slip errors and giving true strain measurements throughout the entire test.
Yes, Testometric systems support ASTM D624 and ISO 34-1 tear testing using trouser, crescent, and angle-shaped specimens. The software automatically calculates tear strength in kN/m and generates compliant reports.
Testometric software includes pre-loaded templates for ASTM D412, D624, D638, D1876, ISO 37, ISO 34-1, ISO 34-2, ISO 527, DIN 53504, and many more rubber and elastomer standards. Auto-calculated outputs include tensile strength, elongation at break, modulus at 100%/200%/300%, and tear strength.
