Flammability Testing

Explanation of Flammability Tests

One of the largest causes for loss in process industries for both equipment and life is fire. The enormous volume and frequency of use of flammable and combustible liquids and gases handled worldwide implies that the risk of industrial accidents is great.

At Fauske & Associates (FAI) we can help you assess your risk exposure by characterizing the flammability potential of your combustible vapors or gases. The following is a list of the most common tests that are performed for flammability hazard characterization and the standards by which FAI can perform these tests; please note that specialized testing can be performed to more closely match your process conditions and thereby better gauge your risk.
