5.2 Castable refractories which are self-flowing at one level of tempering liquid will require vibration for placement at some lower level of tempering liquid. At the tempering liquid levels which require vibration or tamping for placement the castable refractory should be characterized using test methods which are appropriate for castable refractories designed for vibration placement such as Test Method C1445 .
