Flash Point Testers
According to the US Department of Transportation in CFR49; 173.120, Flash point is the minimum temperature at which a liquid gives off vapor within a test vessel in sufficient concentration to form an ignitable mixture with air near the surface of the liquid. Regulation defines the test methods allowed for differing types of liquids and all of our testers fit into one or more of these definitions.
Our flash point testers from Stanhope Seta; include models for ASTM D93 Pensky Marten, D56 TAG Closed Cup, D92 Cleveland Open Cup and D3828 (D3278) Small Scale Closed Cup Rapid Equilibrium method. We also have available a combustibility tester for ASTM D4206 for mixed samples.
The Small Scale Closed Cup, first developed by Stanhope Seta as the Setaflash tester, can be used in lieu of either a Pensky Martens or a TAG Closed Cup Tester on the relative materials, referring to DOT CFR49;. This is a real advantage in that you can test both types of materials on just one tester. Other advantages include a smaller sample size (2-4 ml) and a shorter test time (anywhere from one to twenty minutes depending on method.) It is also much easier to use than other types; particularly in the manual versions.
Setaflash is specified by ASTM D1655 and the UK DefStan 91-91 for testing aviation Turbine fuels, Diesel (D975), fuel oil (D396), gas Turbine fuel (D2880), Dxx Biodiesel blends and Kerosine (D3699). It is the only instrument recommended for testing waterborne paints.
Our Series 3 manual testers are available with or without an “Active Cool” component to cool sample cup between samples. They do include automatic temperature control and flash detection, however the operator needs to dip the test flame.
Our Series 8 automatic testers likewise are available with or without “Active Cool”. With “Active Cool” and a water bath attached the low temperature model can test throughout a range of minus 20C to plus 131C. Without “Active Cool” the higher temp model has a range of Ambient plus 5C through 300C.
