33、/mmm through 150 N/mmm, and afactor of 1.25 for design strength designations in excess of 150N/mmm.C655M 112NOTE 3As used in this specification, the 0.3-mm crack is a testcriterion for pipe tested in three-edge bearing test and is not intended asan indication of overstressed or failed pipe under ins

34、talled conditions.NOTE 4Ultimate strength of concrete pipe in the buried condition isdependent on varying soil bedding factors and varying failure modes andshall not necessarily have a relationship to the ultimate strength as definedunder three-edge bearing conditions.7.2 Test Equipment and Faciliti
