Opis usług: 

The Department of Solid Fuels Quality Assessment has worked continuously since 1945.
Its highly skilled personnel, modern equipment and efficient management system ensure the accuracy, timeliness and reliability of the performed tests.
The Department conducts tests of solid fuels, solid biofuels, solid secondary fuels, mixtures of solid biofuels and solid secondary fuels with solid fuels and of waste (code 10 01 excluding 10 01 09).

The Department has:
