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.

• Measuring Flash Point

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

The Elcometer 6910/2 Setaflash Series 3 Open Cup Tester offers the fastest and most accurate Flash Point instrument at a cost effective price. 

Certain substances, classified as “flammable” by Closed Cup Flash Point Testing, may be reclassified as “non-flammable” by combustibility testing. This has significant potential cost reduction implications for the packaging, storage and shipping of many materials.

The Elcometer 6910 Setaflash features an open cup for flash/no-flash finite determinations or sustained combustion tests, audible and on-screen prompts and easy calibration. Flash Point tests can be conducted in less than two minutes with a temperature range from ambient to 300°C (572°F)

A manually operated flame sweeping arm is fitted to the cup and gas is supplied from the integral tank via the control valve. The flash or sustained combustion characteristics of the sample are observed visually by passing the test flame over the sample.
