Our ash determination equipment provides precise testing of ash content in petroleum products, lubricating oils, fuels, coal, coke, engine coolants, and petroleum coke. All instruments are CE marked and comply with international standards, including ASTM, ISO, DIN, and IP. Designed for laboratories, these muffle furnaces ensure accurate, safe, and efficient ash testing with advanced thermal control.

Ash Determination Test Methods
• ASTM D482 · IP 4 · ISO 6245 – Ash from Petroleum Products
Determines ash in petroleum fuels, crude oils, lubricants, waxes, and related products (0.001–0.180 mass %).
• ASTM D1119 – Ash in Engine Coolants
Measures ash content of commercial coolants and antirust formulations, before and after use.
• ASTM D3174 – Ash in Coal and Coke
Determines inorganic residue in coal and coke samples.
• ASTM D4422 – Ash in Petroleum Coke
Evaluates ash content in petroleum coke for quality and process control.
