Description
FNCT is used to determine the stress cracking resistance of polyethylene materials in any environment.A test specimen in the form of a square-section bar with coplanar notches in each face at the center,is subjected to astatic tensile load in a temperature-controlled environment,for example air,water,surfactant solution. The geometry of the specimen is such that plane strain conditions are obtained and brittle failure occurs under appropriate tensile load and temperature conditions.The time for this brittle failure to occur after loading is recorded.
Load range: 20N~5000N
Load accuracy: ±1%(with self-calibration function)

Standard
ISO 16770 Full notch creep test ISO 899 Tensile creep (Optional) ISO 3501 Test of resistance to pull out of joins between polyethylene pressure pipes and fittings (Optional)

Features

1.6 individual controllers, one for each station.
2. Individual test bath for each station, temperature and force can be set dividually.
3. High accuracy of the regulation of force and elongation.
4. Automatic diagnosis and with protective function.
