The Wincom Cleveland Open Cup (COC) Flash Point Tester is a precision laboratory instrument engineered to determine the flash and fire points of petroleum products, viscous materials, and lubricating oils that have a flash point above 79 degrees Celsius. Operating strictly in accordance with international testing standards such as ASTM D92, this open cup apparatus is crucial for evaluating the flammability, thermal stability, and safety limits of heavy petroleum materials during storage, transport, and operation.

Technical Specifications

• Temperature Testing Range: 80 degrees Celsius to 400 degrees Celsius

• Temperature Measurement Resolution: 0.1 degrees Celsius

• Heating Rate Control: Adjusts accurately to match standard method specifications (e.g., 14 to 17 degrees Celsius per minute initially, and 5 to 6 degrees Celsius per minute near the flash point)

• Ignition Source: Gas flame test sweep arm (or automated electronic ignition depending on the configuration)

• Test Flame Diameter: Standard gauge alignment (3.2 mm to 4.8 mm tool included)

• Power Supply: AC 220V, 50Hz

• Heating Power: Up to 1000W adjustable heating element

Key Features

• Standard Cleveland Open Cup Design: Features a solid, heavy-duty brass test cup built exactly to standard dimensional specifications to guarantee uniform heat transfer and repeatable testing environment.

• Precise Flame Sweep Arm: Equipped with a smooth manual or motorized sweep mechanism that passes the test flame across the open cup center at the exact required distance and speed.

• High-Efficiency Heating Element: Designed with an adjustable open heating plate or solid-state voltage regulator that gives the user precise control over the critical temperature ramp-up rate.

• Integrated Thermometer Holder: Sturdy adjustable fixture ensures the laboratory thermometer or digital PT100 temperature probe remains suspended at the perfect depth without touching the cup walls.

• Durable Safety Construction: Built with a heat-resistant outer casing and a stable desktop platform to protect operators from high working temperatures.

Primary Applications

• Lubricants and Heavy Fuels: Testing the flash and fire points of engine lubricants, gear oils, hydraulic oils, industrial grease, and heavy residual fuel oils.

• Bitumen and Asphalt Industry: Safety screening and quality certification for asphalt binders, liquid bitumens, and road construction chemicals.

• Quality Control and Safety Logistics: Checking high-temperature flash lines for specialty coatings, chemical compounds, and polymer materials to comply with fire safety laws.
