DUS 2067:2018 Standard Test Method for Sulfated Ash from Lubricating Oils and Additives, First Edition. (13 page(s), in English)
This Draft Uganda Standard covers the test method for the determination of the sulfated ash from unused lubricating oils containing additives and from additive concentrates used in compounding. These additives usually contain one or more of the following metals: barium, calcium, magnesium, zinc, potassium, sodium, and tin. The elements sulfur, phosphorus, and chlorine can also be present in combined form. Application of this test method to sulfated ash levels below 0.02% by mass is restricted to oils containing ashless additives. The lower limit of the test method is 0.005% by mass sulfated ash.
