with Seta Flash point testers…

International fuel specification ASTM D975 permits the use of both Setaflash and Pensky Martens test methods, stating ‘D3828 (Setaflash) can be used as an alternative test method to ASTM D93 (Pensky Martens) for all grades of fuel.... ‘

Setaflash test methods, which include ASTM D3828 and D3278, are the trusted tests for rapid determination of flash point and there is established correlation between Setaflash and other flash point tests, including Pensky Martens and Tag (ASTM D56).

Tests for flash point on contaminated fuel samples are a good example of the significant advantages offered by the ‘flash-no flash’ test method.

Fuel samples that are contaminated with ‘light end’ materials ie: with materials more volatile than the fuel itself, are extremely difficult to obtain a repeatable and precise flash point result. One reason is that the contaminant will disperse during sample heating or may even cause a premature, often irreproducible flash.

Setaflash requires a much smaller volume of sample, just 2 or 4ml by comparison to 75ml needed for a Pensky Martens test. As a result the heating and test cycle occurs much more rapidly with less time for volatile components to disperse.

The Setaflash ‘ramp’ mode allows a laboratory to rapidly test a small volume of sample on a rising temperature equilibrium cycle until a flash point is determined. In addition all Setaflash testers are equipped with automatic flash detectors which eliminate much of the guesswork and which help to provide repeatable results.

The latest Series 8 Model is part of the Setaflash range of instruments which offer the fastest way of measuring flash point. The Series 8 range uses an electronic ignitor or optional gas flame accessory according to user preference. The ActiveCool version incorporates peltier heating and cooling which will rapidly reduce the cup temperature after a test is completed thus allowing fast sample removal and shorter test cycle.
