Cleveland Open Cup Flash Point Tester

The instrument can automatically test the flash point and ignition point of petroleum products (the ignition point of oil exceeding 80 ° C, except crude oil and petroleum fuel)， and can be compared with the test results of manual instruments, very simple and convenient.

Meets the ISO 2592 standard. Its programmable logic controller and touch screen (5.5 ") help automate testing, and managing test results is easy.

Application

Covering Multiple Industries, Driving Safety and Efficiency Upgrades

Petrochemical Industry

Refining and Quality Inspection: Monitoring flash point changes in processes such as crude oil distillation and lubricant blending to ensure product quality. For example, a refinery reduced the lubricant rejection rate from 2% to 0.5% by real-time flash point detection.

Asphalt Production: Testing asphalt flash point to meet JTJ052 standards and prevent spontaneous combustion risks during transportation.

Power and Energy Sector

Transformer Oil Testing: Determining the flash point of transformer oil according to DL/T 596 standard to assess its insulation performance and aging degree. For example, a power plant found that the flash point of a transformer oil had dropped to 130℃ through testing, and timely replacement prevented equipment failure.

New Energy Research and Development: Studying the flash point characteristics of new fuels such as biodiesel and hydrogen carriers to promote the application of clean energy.

Transportation Industry

Railways and Aviation: Detecting the flash point of locomotive oil and aviation lubricants to ensure operational safety. For example, an airline found that the flash point of a batch of aviation fuel was too low through testing, and suspended the use of that batch of fuel to avoid flight accidents.

Test Procedures

Sample Preparation: Heat the sample until it becomes fluid, then pour it into the cup up to the marked line, avoiding contamination of the cup walls.

Heating Control: In the initial stage, heat rapidly at 14-17℃/min, then slow down when the temperature reaches 56℃ below the expected flash point.

Critical Stage: When the temperature is 28℃ below the expected flash point, control the heating rate to 5.5℃/min ± 0.5℃.

Ignition Determination: Sweep a flame across the cup opening every 2℃ increase in temperature. Record the temperature when a transient blue flame appears and immediately extinguishes.

Test Completion: Clean the equipment and switch off the power supply.

FAQ

1. What is the primary purpose of this tester?

It determines the flash point of flammable liquids, oils, and chemicals using the Cleveland open cup method to assess fire and safety hazards.
