The flash-point of the test substance was determined to be 100 and 101°C. The difference between the results obtained with the two tests was 2°C. From this, it was concluded that the flash-point of the test substance is the lowest flash-point obtained. 

 

Conclusions:
The Pensky-Martens closed cup method was applied for the determination of the flash-point of 2-sec-butylphenol. The flash-point of the test substance was 100°C.

Executive summary:

The flash point of the test substance 2 -sec-butylphenol was determined by the Pensky-Martens closed method. The method followed the EU Method A.8. (Flash Point), the ISO No. 2719:2002 (Determination of flash point - Pensky-Martens closed cup method) and the ASTM International, ASTM D 93 (Standard Test Methods for Flash Point by Pensky-Martens Closed Cup Tester). The estimated flash-point of the test substance in the preliminary test was 102°C. In the main study, two tests were performed. The difference between the results obtained with the two tests was 2°C (100 and 101°C). From this, it was concluded that the flash-point of the test substance is the lowest flash-point obtained. 

The flash-point of the test substance was 100°C.
