We test TSE to ISO 10307-1 / ASTM D4870 / IP 375. Measuring TSE along with TSP/TSA and SN data, we can provide a greater understanding and assessment of the fuel’s potential sediment behaviour.

During secondary refining the fuel stability reserve may be reduced creating instability. Asphaltenic drop-out causing sludging, which can block filters, pipework and lead to the engine being starved of fuel and engine black-out.

TSE is used to assess the Cleanliness of the fuel – i.e. inorganic foreign matter such as sand, rust, dirt, cat-fines. Assessment of whether sludge is from dirty or unstable fuel, will identify if current system is capable of coping with such fuel.
