– Used to assess the ability of oil to corrosive to corrosive metals. – The sulfur compounds in oil will cause corrosion of many different metals. – Corrosion is defined as an oxidation on metal surfaces causing metal loss or accumulation of deposits. – Hydraulic oil, aviation oil, metal cutting oil, especially transformer oil and […]

The purpose is to assess the degree of contamination or loss of quality (heat and chemical) of the oil. Insoluble residue = soot, dust, metal fragments (due to abrasion), products of oxidation and hydrolysis … Determined by the following methods: Total insoluble residue: Number of mg of residue collected after filtering 100ml of oil => […]

Sulfate ash content is the amount of residue left after completely burning the oil sample. Car engine oil: Sulfate ash content Determination method: ASTM D 874 – Petrol engine oil: sulfate ash ≤ 1,5% m – Diesel engine oil: sulfated ash ≤ 2% m

Density is the ratio of the density of a given substance at a specified temperature (15 ° C or 30 ° C) to the density of pure water at a specified temperature (15 ° C or 30 ° C). ). The density and density of a substance are equal if considering the density of water […]
