This document specifies a method to determine the resistance to internal pressure of polyethylene (PE), crosslinked polyethylene (PE-X) and unplasticized (PA-U) pipes to verify the condition of the pipe after being subjected to a squeeze-off procedure.
The equipment and procedure used to prepare the test samples and test parameters are given in this document, i.e.:
a) the diameter and series of the pipe to be tested (see 6.1);
b) the number of test pieces (see 6.2);
c) the parameters for the hydrostatic strength tests (see 7.6).
NOTE 1 - Further information on the squeeze-off procedure is given in EN 12007-2 and ISO/TS 10839 for polyethylene, and CEN/TS 12007-6 for unplasticized polyamide.
NOTE 2 - The squeeze-off procedure is specified to limit gas flow to allow maintenance, repair or to make network connections. Squeeze-off is used in an emergency for pipes carrying other media.
