Accelerated test for PE 100 and PE 100 RC pipes grades
Original language description
The failure mode called long time brittle failure (due to small crack growth ? SCG) limits the lifetime of plastic pipes. Nowadays there are two accelerated tests (PENT and FNCT) that enable to estimate the lifetime of HDPE using in plastics pipes. For unimodal grade the time to failure according these accelerated tests is about tens hours, for bimodal grade PE 100 it is roughly thousands hours and for the new PE 100 RC grade is greater than 1 year. For the HDPE pipes grade with higher resistance against SCG some modification or alternatively new tests should be developed that enable even for these materials to obtain the results in relatively short time. In this contribution we focused mainly on some modification of PENT and FNCT and possible correlation between mechanical and structural test.
