This is our cubic meter chamber, one of only a few in the United States. The cubic meter chamber is used to verify the results found in the smaller 20 liter test vessel.
Earlier we learned about Kst values. As a general rule, Kst values less than 50 would be a great candidate to clarify testing results within the cubic meter chamber. The tests performed in this chamber are the screening test, also known as the challenge test. Other tests are the Kst minimum explosible concentration, and limiting oxygen concentration. Keep in mind the amount of sample that's needed to do testing inside the cubic meter chamber. Many of the tests require a minimum of 20 to 30 pounds of sample. This is one area where our dust kit just won't cut it for this test.
Many clients will send their sample in a 55 gallon drum. The Fauske onsite service team is available to come to your facility or just help you with the next phase of the process and decide on what testing is now needed. Fauske & Associates is here for you to serve your process safety needs. Let us know how we can be a resource. Fauske & Associates, world leader in nuclear and chemical process safety.
