This document specifies methods for determining the ring creep properties for glass-reinforced thermosetting plastics (GRP) pipes. Properties include the creep factor and the long-term specific creep stiffness. Testing is performed under either wet (total immersion in water) or dry conditions.
Dry creep testing is typically performed for the assessment and control of raw material consistency.
Wet creep testing is typically undertaken to determine the long-term creep performance in simulated use conditions.
