DETERMINATION OF RESISTANCE TO RAPID CRACK PROPAGATION (RCP) (TS EN ISO 13477)

This Method specifies a small-scale (S4) test method for determining the arrest or propagation of a crack initiated in a thermoplastics pipe at a specified temperature and internal pressure. A section of thermoplastics test pipe of specified length, conditioned to a specified test temperature and containing a fluid at a specified test pressure, is subjected to an impact near one end, designed to initiate a fast-running longitudinal crack. The crack-initiation process itself is designed so that it disturbs the test pipe as little as possible. The test pipe is examined to determine whether arrest or propagation of the crack has occurred.
