Anotace textu normy ASTM D2996-23 :

This specification covers machine-made reinforced thermosetting resin pressure pipe (RTRP) manufactured by the filament winding process. This specification does not include reinforced polymer mortar pipe (RPMP), which is another type of fiberglass pipe. The pipes are generally classified by type, grade, class, and hydrostatic design. In addition, a secondary cell classification system defines the basic mechanical properties of the pipe. The resins, reinforcements, colorants, fillers, and other materials, when combined as a composite structure, shall produce a pipe that shall meet the performance requirements of this specification. Materials shall be tested and the individual grades shall conform to the specified values of dimensions and tolerances, long-term static hydrostatic strength, long-term cyclic hydrostatic strength, short-term hydrostatic failure strength, longitudinal tensile properties, and stiffness factor.
