Question:
Pensky Martens closed tester is used for determination of which of the following property of fuel?
Pensky Martens closed tester is used for determination of which of the following property of fuel?
Show Hint
Remember the two main flash point testers:
- Pensky-Martens (Closed-cup) and Cleveland (Open-cup). Both are used strictly for identifying the flash and fire points of fuels and lubricants.

The Correct Option is C
Solution and Explanation
Step 1: Understanding the Concept:
The flash point of a fuel is the lowest temperature at which its vapors will ignite momentarily (flash) when exposed to an open ignition source.
Step 3: Detailed Explanation:
The Pensky-Martens closed-cup tester (ASTM D93) is a standard laboratory apparatus designed to determine the flash point of fuel oils, diesel, biodiesel, lubricating oils, and other flammable liquids.
The closed cup configuration prevents vapors from escaping, yielding a precise and safe measurement of the temperature at which a ignitable vapor concentration accumulates.
Step 4: Final Answer:
The correct option is 3, which corresponds to Flash point.
