Environmental Stress Crack Resistance Tester, also named Notched constant tensile load tester, NCTL tester or GRI GM5b NCTL Tester, which is used to evaluate the stress crack resistance of polyolefin geomembranes by notched constant tensile load test.
Charpy Pendulum Impact Tester, also named Charpy Impact Tester or Dial Charpy Impact Tester. It is used to determine the energy by the impact of the pendulum. The shock energy of the beam can be defined as the energy absorbed by the sample under the action of impact load. It is a performance index, which can be used in the quality control of the production process.
