Loss on Heating of Oil and Asphaltic Compounds – ASTM Test Method

The Loss on Heating (LOH) test is an essential procedure for evaluating the thermal stability of oils, asphalt binders, and asphaltic compounds. This method measures the loss in mass (excluding water content) when a sample is subjected to controlled heating. It provides critical data for determining the durability, oxidation resistance, and quality of petroleum-based materials.

LT/LH-256000/M – Loss on Heating Oven (ASTM Standard)

The Loss on Heating Oven is designed to perform accurate and repeatable LOH testing in full compliance with ASTM standards. Built for durability and precision, the oven ensures consistent results in the analysis of asphaltic compounds, bitumen, and oils.

Key Features:
• Rugged steel outer body coated with epoxy anti-acid paint for corrosion resistance.
• Inner chamber in stainless steel AISI 304 with rounded corners for easy cleaning.
• Internal dimensions: 403 × 370 × 458 mm (approx.).
• Rotating axle system (5–6 rpm) controlled by a geared motor, located on oven top, designed for container support (ordered separately).
• Double insulation door with silicone seal to minimize heat loss.
• Door equipped with a 200 × 200 mm toughened glass viewing window.
• Thermal insulation with mineral fiber for energy efficiency.
• Digital P.I.D. thermostat with 1°C resolution for precise temperature control.
• Temperature range: +5°C above ambient up to +280°C.
• Integrated safety thermostat for overheating protection.
• Forced ventilation with adjustable manual flow control.
• Power supply: 220 Vac, 50/60 Hz.

This equipment provides accurate loss on heating measurements, making it ideal for research labs, quality control, and industrial asphalt testing applications.
