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.

Conformity Statements and Decision Rules in Reports
The general decision rule for conformity statements in test reports is as follows:
The conformity statement is: meet the requirement or not meet the requirement.
The requirement was evaluated based on a one-sided confidence level of 97.5%.
Specific risk is used for risk evaluation (w = 0, AL = TL).
- Passed:
Measured values (geometric means) are equal to or higher than the requirement.
The distribution of measured values lies within the tolerance limits. - Fail:
Measured values (geometric means) fall below the requirement.
Note:
Decision rules contained in applicable standards or specified by the customer take precedence over this general rule.
