What is PMCC flash point?

LCFP-A10 is compact, stand-alone closed cup flash point tester which determines the low temperature operability in diesel fuel, biodiesel, blends and gas oils. It is designed as per “Test Methods for Flash Point of Petroleum Products (Pensky-Martens Closed Cup Methods)” ASTM D93.

What is a flash point tester?

Flash point testing is a procedure designed to determine whether a sampled mixture of vapour and air is flammable. It can also determine the temperature at which flammability occurs in a sample. The oil industry uses flash point testing for oil analysis.

What is ASTM D93?

ASTM D93 stands for standard test methods for Flash Point by Pensky-Martens Closed Cup Tester. The ASTM D93 standard test method can be devided into three procedures: Procedure A covers destillated fuels such as diesel, biodiesel blends, kerosine, heating oil and turbine fuels.

What is the difference between Abels and Pensky-Martens apparatus?

Able Flash Point Apparatus. It is designed as per I.P. Pensky-Martens Flash Point Tester: PMA 5. The automatic Pensky-Martens closed-cup tester measures the flash point at the lowest temperature at which the application of an ignition source causes the vapors of a sample to ignite.

What is the difference between Cleveland open cup flash point and closed cup flash point test?

Open cup flash point is the flash point we obtain from open cup method where the vapour above the liquid is in equilibriums with the liquid. In contrast, closed cup flash point is the flash point we obtain from the closed cup method where the vapour above the liquid is not in equilibrium with the liquid.

Why closed cup apparatus is more reliable than open cup?

Closed cup testers normally give lower values for the flash point than open cup (typically 5–10 °C or 9–18 °F lower) and are a better approximation to the temperature at which the vapour pressure reaches the lower flammable limit.

How many types of flash point are there?

There are two basic types of flash point measurement: open cup and closed cup.

How do you determine flash points?

Flash points are determined experimentally by heating the liquid in a container and then introducing a small flame just above the liquid surface. The temperature at which there is a flash/ignition is recorded as the flash point.

What is ASTM D56?

ASTM D56 test method covers the determination of the flash point using a Tag Closed Cup Tester (see picture below), of a liquid with a low viscosity. The observed flash point shall be corrected for barometric pressure.

Which apparatus is used for Flash & fire point test?

Explanation: Flash Point Apparatus is used for Flash Point and Fire Point estimation.

Can we get accurate flash and fire point by Cleveland apparatus?

When the oil is tested using the open cup apparatus, the temperature is slightly more than the above temperatures. The flash and fire point temperatures may differs by 20°C to 60°C when it is tested by open cup apparatus. However, a greater difference may be obtained if some additives are mixed with oil.
