How much F76 is used for DFWD testing?

• A. 200 mL
• B. 100 mL
• C. 50 mL
• D. 300 mL

Answer: (A)

The main idea is using the exact volume specified by the testing procedure to get a valid and repeatable result. For DFWD testing, the procedure calls for 200 mL of F76. This amount provides the correct liquid depth in the test vessel to ensure proper mixing, measurement, and consistency between runs. Using less would leave the vessel too shallow, which can affect agitation, sample representation, and the accuracy of the test readings. Using more could overflow the vessel or change the test conditions, leading to unreliable data. Therefore, 200 mL is the chosen volume that balances accuracy, safety, and compatibility with the equipment.
