ActiveGlass-reinforced thermosetting plastics (GRP) pipes—Determination of the long-term ultimate bending strain and the long-term ultimate relative ring deflection under wet conditions
玻璃纤维增强热固性塑料（GRP）管 湿态环境下长期极限弯曲应变和长期极限相对环变形的测定
Application Summary AI generated
This standard specifies a test method for determining the long-term ultimate bending strain and relative ring deflection of glass-reinforced thermosetting plastic (GRP) pipes when exposed to wet conditions. It is applied in the pipeline industry for evaluating the structural durability and design life of GRP pipes used in water, wastewater, and chemical transport systems where continuous moisture contact occurs. The standard ensures reliable performance predictions for buried or submerged piping under sustained bending and ring deformation loads.
