Tests include procedures for evaluating external load crushing strength, flat slab top, core strength, absorption, hydrostatic, permeability, manhole step, cylinder, gasket lubricant, joint shear, alkalinity, and gasket measurements.Recommendations for Design of Reinforced Concrete Pipe,,The required strength of the concrete pipe is determined from the effects of the bending moment, thrust, and shear in the pipe wall. Wall thickness, concrete strength, and reinforcement design are evaluated using rational procedures based on strength and crack width limits that were developed in the ACPA long-range research program.Structural Design of Clay Pipes | CPDA,The figures for Crushing Strength and Bending Moment Resistance (B.M.R) in BS EN 295 Part 1 have been established after extensive research into the loads imposed on buried vitrified clay pipelines. The requirements for B.M.R have been set sufficiently high to ensure that pipes conforming to these, and used in a properly constructed pipeline, will not fail in bending before they reach their design crushing
