The lowest flash-point was corrected for the atmospheric pressure (i.e. 102.6 kPa).

Corrected flash-point = 237÷0.25(101.3-102.6)°C= 236.68°C

Rounded off to 0.5°C gives the flash-point for Hatcol 2352: 236.5°C.

Conclusions:
Rounded off to 0.5°C gives the flash-point for Hatcol 2352: 236.5°C.
Executive summary:

The determination of the flash-point was performed in accordance with EEC-Directive 92/69 EEC, A.9 "Flash-point" (1992) and DIN EN 22719: "Bestimmung des Flammpunktes Verfhrennach Pensky Martens im geschlossenen Tiegel"; December 1993.

The atmospheric pressure on the day of the test, was 100.10 kPa.

The lowest flash-point was corrected for the atmospheric pressure.

Corrected flash-point   = 215 + 0.25 (101.3-100.10)°C

= 215.30°C
