Complete assembly consists of Muffle furnace, evaporating dish and Furnace tong.
Compliance with following International Standards:
- ASTM D482, IP 04
Significance & Use:
- This test method covers the 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 test method is limited to petroleum products which are free from added ash-forming additives, including certain phosphorus compounds.
Following Apparatus will be provided to carry out the test:
1) Muffle Furnace Horizontal, front loading type:
- In this improved model, ceramic fiber wool insulation (instead of brick insulation) has been provided resulting in weight and size reduction of furnace. The weight and size of the furnace is 1/4 and 30% less respectively as compared to brick furnace. The heat up time is less. Heat loss is very low-resulting in power saving.
Vent Port:
- Built in vent port for removal of non oxious gases etc. preferably with a provision of connecting the extension pipe with vent lid should be air tight for Volatile Matter analysis.
Calibration port (If required by indenter):
- Provision of hole with cover will be provided in the furnace door for putting temperature sensor for calibration of equipment.
Safety Features:
- Thermocouple breaks protection to cut power to the heating element in order to prevent thermocouple failure runway condition.
- Safety switch to cut of the power in case of door is open
- Hour Meter to indicate actual working hours of Heating Elements
2) Evaporating Dish or Crucible:
- 50 to 100-ml for samples containing more than 0.02 mass % sulfated ash, or 120 to 150-ml for samples containing less than 0.02 mass % sulfated ash
- Made of fused silica
3) Electronic Balance (0.1 mg):
- Make: Reputed make
- Weighing Capacity: 220 gm
- Readability: 0.1 mg
- Repeatability: < 0.1 mg
- Pan Size: 80 mm Diameter
- Calibration: Built in Motorized calibration
