Abstract
Overview
ISO 13480:1997 - "Polyethylene pipes - Resistance to slow crack growth - Cone test method" - specifies a laboratory test to quantify the resistance of polyethylene (PE) pipe to slow crack growth (SCG). The method measures the rate of crack propagation from a single notch in a notched pipe ring held at a constant hoop strain while immersed in a surface-active solution at elevated temperature. The standard was prepared by ISO/TC 138 (Plastics pipes) and applies to pipe wall thicknesses up to and including 5 mm.
