In the last years effort has been made to develop and standardise new accelerated test methods to evaluate PE 100-RC materials in short times in form of test bars. The two most important developments, the cracked round bar test (CRB test) and the strain hardening test (SH test) were published as final ISO standards in the year 2015 in ISO 18489 and ISO 18488.
For a complete evaluation of a PE pipe material and for evaluation of products in form of pipes and fittings also test methods with specimens in form of pipes are required. In the last years the notch pipe test according ISO 13479 and the point load test, which is still under development as an ISO/PWI 22102 in ISO/TC 138/SC 5/WG 20, have been used to evaluate the slow crack growth (SCG) behaviour of such materials in form of pipes.
In this presentation the actual status of the point load test (PLT) development will be shown as well as the development of an accelerated notch pipe test (ANPT), which has been reported first in 2008.
