ASTM D874 Sulfated Ash From Lubricating Oils And Additives
Brand KN
Product origin Dalian,China
Delivery time deliver as soon as received payment
Supply capacity 30 sets one month
The sample is ignited and burned until only ash and carbon remain. After cooling, the residue is treated with
sulfuric acid and heated at 775°C until oxidation of carbon is complete. The ash is then cooled, re-treated with sulfuric acid, and heated at 775°C to constant weight.
KN-482 Ash Content for Petroleum Product
Overview
This oven conforms to the ASTM D482 Standard Test Method for Ash from Petroleum Products and ASTM D874 Standard Test Method for Sulfated Ash from Lubricating Oils and Additives it is used for determination of ash in the range 0.001–0.180 mass %, from distillate and residual fuels, gas turbine fuels, crude oils, lubricating oils, waxes, and other petroleum products, in which any ash-forming materials present are normally considered to be undesirable impurities or contaminants. The apparatus is limited to petroleum products which are free from added ash-forming additives, including certain phosphorus compounds.
