Flash Point is defined as “the lowest temperature of a liquid at which its vapours will form a combustible mixture with air”. It is a convenient and reliable classification of the “flammability” of many substances.
- Open Cup tests simulate an un-contained condition, for example a spillage.
- Closed Cup tests simulate an enclosed environment, for example storage in a tank or sealed container and are usually specified due to improved precision.
Most industries need to test the Flash Point of raw materials, products or waste to ensure:
Product quality - as a measure of consistency and performance comparison
Compliance testing - to test safety classification for handling, storage, transport and waste
In-service analysis - tests on in-use oils and other substances for contamination / adulteration
General safety - to evaluate hazard potential
Specifications - to check conformance
A wide range of features ensures ease of operation and requires minimum operator skill. Test parameters are set via the keypad and a digital display provides temperature, sample size, test time and flash detection status. Default ‘Auto’ values are available for standard test conditions.
The Elcometer 6910 Closed Cup Tester can test from ambient to 300°C (572°F). Temperature is factory calibrated but facilities for user verification and calibration are incorporated.
Flash Point is automatically detected using a thermally activated detector, reducing the risk of operator error and minimising the potential danger of inhaling fumes during a test. A rechargeable gas tank with On/Off switch and fine adjustment are integral to the unit. Supplied with a 2ml (0.067fl oz) syringe and ignitor.
To test below the ambient temperature, an optional cooling module, suitable for temperatures as low as 0°C (32°F), should be ordered.
