They must not leak when water is poured into them empty. Vibrators or rodding are entirely interchangeable, but vibrators must be used for slumps 1" or less. When planning to mold and cure concrete specimens, it is required that tests for slump, temperature, and air content be performed unless entrained air is not of concern to the project.
