Which two fuels volumes are used for DFWD testing (F76 and JP-5)?

Explanation:
In DFWD testing, the procedure specifies exact volumes of the two fuels to create a consistent test environment. The required combination uses 200 mL of F76 and 800 mL of JP-5, totaling 1 liter. This 1:4 ratio fulfills the standard test condition, ensuring the test article is exposed to both fuels in the intended proportions and the vessel is filled to the correct level for reliable measurements. Other volume options would either underrepresent F76 or alter the JP-5 dominance, leading to non-standard test conditions and less reliable results.
