Step-6 Place the base plate over a fine sand layer (5mm max thick) at center of the main ISM 300 (load carrying girder at center of stage) and centering by using plumb bob & spirit level.Step-7 After finish the plate installation adjustment hight are place above the plate carefully.Then hydrolic jack place properly that the load from bead transfer through jack to plate **If water come over plate or test location from ground then remove water by pumping Step-8 Now applying the initial load and then applied 1st load, 2nd load, 3rd load .... Continue to ultimate load or failure occurred. For each load increment settlements should be observed an interval of 1, 2.25, 4, 6.25, 9, 16, 25, 60 min. Load increment stop If settlement rate more than 0.02 mm/min. and check settlement continue hourly. Eatch load increment shall be kept for not less than 1 hours. The test shall be continue till 25mm (50mm in special cases) or failure occurs.
