The specific gravity of the material shall b e determined with a Westphal specific gravity balance in accordance with the following procedure. a. Calbirate the balance at the test temperature by the following procedure, Fill the sample graduate wi

27、th freshly boiled, cool, distilled water. Clamp the graduate in place in a constant temperature bath set at 20 plus or minus 10 degrees C. Allow 15 minutes conditioning time to achieve temperature equilibrium. Remove the sample graduate from the bath and place it on the balance. Insert the plumb bob

28、 in the distilled water. Adjust the rider and vernier scale on the balance to give a reading of 1.000. This is the specific gravity of distilled water at the test temperature. b. Fill a sample graduate with the liquid to be tested. Clamp the graduate in place in the constant temperature bath and con

29、dition the sample for 15 minutes. c. Remove the graduate from the bath and place it on the balance and read the balance when it reaches equilibrium. Perform this step as rapidly as possible to minimize temperature changes. For accurate work, the plumb bob should be immersed to the same depth for eac

30、h determination. d. Record the balance reading as the specific gravity of test sample at the conditioning temperature. Duplicate results must check within plus or minus 0.002 unit or additional samples must be run. 6 Provided by IHSNot for ResaleNo reproduction or networking permitted without licens
