Many questions about foam, one universal approach: The DFA100 Dynamic Foam Analyzer measures the foamability of liquids and the stability of quickly decaying or long lasting foam based on reproducible foaming and height detection. Shake test: Add the defoamer to the bubble solution, shake it by hand, observe it at regular intervals, and record the defoaming time. shampoo sample into a 100 mL graduated cylinder. It involves placing diluted shampoo solution in a graduated cylinder, sealing the cylinder and then rotating it a number of times to create the foam. A cylinder foam evaluation test was performed to determine foam formation and retention. Shake the cylinder up and down 10 times. [9] Foaming ability: This was performed by using cylinder shake method. Find out how fire extinguishers work and how to use them … • 50 mL graduated cylinder • 2 eyedroppers • 1 glass 125 mL wide mouth jar (4 oz mason jar) with lid • 1 plastic 250 mL bottle for making AEA solutions • 1 balance The Foam Index Test Procedure 1.

Add 5 drops of oil to each test tube from step 14. 1.2 The values stated in SI units are to be regarded as standard. Observe and record the amount of suds or foam each soap solution produces. The foam volume was on a par. Test to evaluate foaming ability and foam stability. Designed to hold NFPA 11 Foam Collection Cylinder (included in Foam Concentrate Test Kit) or ICAO Foam Collection Cylinder. 1 Pages. If the foam height reaches the 100mm mark before 300 seconds, the time taken to reach this height is recorded. 10. With optional modules operating in parallel, it also measures the liquid content or analyzes the foam … 1.1 This test method applies to a simple shake test for evaluating the tendency of an aqueous solution of engine coolant to foam at room temperature.
