  • Point Loading Test under accelerated test conditions (PLT+)

    Point Loading Test under accelerated test conditions (PLT+)

    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 PLT under accelerated test conditions (PLT+) was developed by HESSEL Ingenieurtechnik with the aim of accelerating the characterization of the stress crack behavior of PE 100-RC pipes.

    The PLT+ is an internationally established testing procedure to demonstrate suitability for alternative installation methods.

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.
