Full Notch Creep Tester (FNCT)

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.
