    Revision of C1818 - 19 Standard Specification for Synthetic Fiber Reinforced Concrete Culvert, Storm Drain, and Sewer Pipe

    (What is a Work Item?)

    Active Standard: C1818 - 19

    Developed by Subcommittee: C13.02 | Committee C13 | Contact Staff Manager



    circular pipe; D-load; sewer pipe; storm drains; Syn-FRCP; synthetic fibers; three edge bearing strength;;


    Three manufacturers participated in comparison testing of a given size and class of pipe and obtained inconsistent results from application of current ASTM C 1818 test methods. One manufacturer tested pipe that presented ductile response with several cracks forming before ultimate load was reached. Another met the requirements for Ultimate load with simultaneous quadrant cracking similar to a non-reinforced pipe but failed the reload. The third noticed performance between the two but was unable to meet the ultimate load or the reload for 24 CL3 pipe. After considerable discussion, it was suggested that the test methods detailed in the standard as written do not provide for a consistent performance in the product covered by the standard. To allow for the standard to be rewritten to address these inconsistencies and to prevent end users from receiving product that does not perform to their expectations, the standard is recommended to be withdrawn.
