Conclusions:
The mean flash point of Benzene-1,4-diammonium sulphate (CAS No. 16245-77-5) is 138.6°C at 977.1hPa.
Executive summary:

The flash point determination of Benzene-1,4-diammonium sulphate (CAS No. 16245-77-5)was done following closed cup method using Pensky-Martens flash point apparatus. The test was conducted in replicates and mean flash point was found to be 138.6°C at 977.1hPa. 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.
