Detailed Product Description
ISO812 ASTM D2137 Rubber Low Temperature Brittleness Tester
This professional rubber testing instrument evaluates the low-temperature performance and brittle temperature of vulcanized rubber specimens under controlled impact conditions.
Product Overview
The Rubber Low-Temperature Brittleness Tester determines the adaptability of electrical, electronic, automotive electrical, and material products under low-temperature storage and usage conditions. It is widely used in schools, factories, military units, research institutions, and other organizations.
Testing Method
Five specimens are fixed on the suspension fixture and immersed in the low-temperature bath. A rotating pendulum hammer strikes the specimens at a constant speed to check for cracking. The instrument measures the highest temperature at which vulcanized rubber specimens break under impact, evaluating the brittle temperature and low-temperature performance of different rubber materials or formulations.
Key Features
  • Compressor refrigeration system ensures minimal temperature fluctuation
  • Pneumatic impact control for precise testing
  • Complies with national standard GB/T1682 requirements
  • Professional-grade construction for industrial applications
