Accelerated Creep Test (ACT)

The PE 100-RC materials described in PAS 1075 are characterized by very high stress crack resistance. The verification of the stress crack resistance of PE 100-RC materials requires an acceleration of the testing procedure.

The FNCT under Accelerated Creep Test conditions (ACT) was developed by HESSEL Ingenieurtechnik with the aim of accelerating the characterization of the stress crack behavior of PE 100-RC materials.

The ACT is an internationally established testing procedure and is preferred for reliable quality control and batch release.
