Samyon Fnct-2026 Testing Equipment for Engineering Plastic (20N~5000N)

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.
