Executive summary:

The flash point determination of test substance 3H,3'H-2,2'-bi-1-benzothiophene-3,3'-dione was done as per the test guideline OECD 103. The method is closed cup method using Pensky Martin’s Flash Point Apparatus. The flashpoint of the test substance was determined to be 105 °C at 980.9 hPa. Based on criteria mentioned in CLP regulation the chemical has flash point >than 60 degree C hence the substance was considered to be non-flammable.
