FULL NOTCH CREEP TESTER (FNCT) Overview 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 a static 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. Standard ISO 16770 Full Notch creep test method; ISO 899 Tensile creep (Optional); ISO3501 Test of resistance to pull out of joins between polyethylene pressure pipes and fittings— (Optional, should be ordered specially)
