Product Introduction
Summary
The instrument is designed and made as per national standard of People’s Republic of China GB/T508 Standard Test Method for Ash Content of Petroleum Products. It is suitable to determine ash content in the petroleum products as per GB/T508. It could not be used to determine ash content in the petroleum products containing ash-forming additives (including additives containing certain phosphorus compounds), lubricating oils containing lead, and used engine crankcase oils.
The method summary of ash content test: Take ashless filter paper as ignition core. Ignite the sample in the crucible to make it burning to ash and carbon residue. Heat the carbon residue at 775℃ in the high temperature furnace to make it convert to ash. Then cool down and weigh the mass.
