                 Free alkali:0.3-2

                Specific gravity(25 degree): 1.0±0.05


                Spray pressure: 0.8-2.0bar


                Dipping time:3-15minutes

                Spray time:60-80seconds



Testing method: free alkali: pipet 10ml sample into 250ml conical beaker, add 2-3 dripping phenolphthalein indicator, after drop 0.1N hydrochloric acid till pink disappear. The consumption of the hydrochloric acid is same as free alkalinity.
