ASTM D482 Ash Content Tester
ASTM D482 Ash Content Tester
MT-AC68
The ASTM D482 Ash Content Tester is designed for determining the ash content in petroleum products under controlled laboratory conditions. The instrument is manufactured in accordance with GB/T 508 – Test Method for Ash from Petroleum Products, which corresponds to ASTM D482.
Introduction
Ash content represents the inorganic residue remaining after the complete combustion of petroleum products. It is an important indicator used to evaluate contaminants, metallic compounds, and inorganic impurities present in fuels and lubricating oils.
During the test, the sample is ignited using ashless filter paper as a wick and allowed to burn until only carbonaceous residue remains. The residue is then heated in a high-temperature furnace at approximately 775°C, where it is converted into ash. After cooling, the ash residue is weighed to determine the ash content of the sample.
The ash content tester mainly consists of a high-temperature furnace, temperature controller, porcelain crucibles, ashless filter paper, and handling tools. The temperature controller allows accurate measurement, display, and regulation of furnace temperature to maintain stable testing conditions.
This instrument is widely used in petroleum refineries, fuel testing laboratories, petrochemical plants, research institutes, and quality inspection agencies.
