*Materials Test Cryostats
100 kN Tensile Test Cryostat
- The versatile cryostat is for low-temperature tests (4 K to 300 K);
- Metals
- Polymers
- Composite specimens
- Typically used for tensile tests at ambient temperature (295 K) and cryogenic temperatures of 77 K and 4 K in liquid nitrogen or liquid helium.
- Description:
- 100 kN capacity, 3-post self-reaction frame
- Test sample space 115 mm dia x 430 mm length.
- Threaded high strength stainless steel pull rods
- Grips and fixtures designed per customer request
Model MR-001-25 D-Gage-A Set of 3 Averaging High-Resolution Extensometers for Low Temperature Tests
- Designed for tensile testing according to ASTM E8 and ASTM E1450 (ISO 6892-1 and ISO 6892-4)
- Set of 3 is used on round tensile specimens for accurate modulus measurements according to ASTM E111
- Gage block is used to install extensometer attachment collars.
- Attachment collars enable a safe fall-away design at the end of extensometer travel
- Custom designs, resolutions, and strain range capabilities are available upon request
Crack Opening Displacement (COD) Gages for Fracture Mechanics Testing
- Designed for Fracture Toughness and Fatigue Crack Growth Rate testing according to ASTM E399, ASTM E1820, ISO 12135, and ASTM E467
- Especially designed for low-temperature tests at liquid nitrogen or liquid helium
- Can be used on Compact Tension Specimens or 3 Pt Bend fracture toughness specimens
- Custom options available for various specimen sizes and applications
*Grips and Pull Rods
Flat Specimen Friction Grip Solutions for Low Temperature Tensile Tests
- Bolt-together Grips replace unreliable bulky wedge grips for tests up to 50 kN
- Versatile design for cryogenic tensile tests as a replacement solution for bulky wedge grips
- Typically used for low temperature tests at liquid nitrogen (77 K) or liquid helium (4 K)
