ASTM D2137 Low Temperature Brittleness Tester CF8387

The CF8387 Low Temperature Brittleness Tester determines the lowest temperature at which rubber and elastomeric materials do not exhibit brittle failure under impact conditions, per ASTM D2137 and ISO 812. This critical test evaluates cold-temperature performance of rubber products used in automotive, aerospace, and industrial applications in extreme environments.

Key Features

ASTM D2137 & ISO 812 Compliant: Standard impact hammer method with specified striking edge geometry for reproducible brittleness temperature determination.
Wide Temperature Range: Mechanical refrigeration system with PID control provides stable test temperatures from ambient to -70°C without liquid nitrogen.
Precision Impact Mechanism: Motor-driven hammer with 1.98m/s ±0.10m/s linear striking speed ensures consistent impact energy across all tests.
Multi-Specimen Clamp: 5-station specimen holder with rapid immersion cooling for simultaneous testing and efficient batch throughput.
