36、in three-edge bearing test and is not intended as an indicationof overstressed or failed pipe under installed conditions.NOTE 4Ultimate strength of concrete pipe in the buried condition is dependent on varying soil bedding factors and varying failure modes and shallnot necessarily have a relationshi
37、p to the ultimate strength as defined under three-edge bearing conditions.7.2 Test Equipment and FacilitiesThe manufacturer shall furnish without charge all samples, facilities, and personnelnecessary to carry out the tests required by this specification.7.3 Pipe Load TestsThe tests for crushing str
