Question

What action must be taken if the sample flashes upon the first application of the flame during a flashpoint analysis?

A) Repeat the test with a higher flame
B) Record the flashpoint as observed
C) Use a different sample
D) Conduct the test in a different environment

Answer 1

If the sample flashes upon the first application of the flame during a flashpoint analysis, the flashpoint should be recorded as observed.

Step-by-step explanation:

If the sample flashes upon the first application of the flame during a flashpoint analysis, the correct action to take is to record the flashpoint as observed. Flashpoint analysis is used to determine the lowest temperature at which a substance gives off enough vapor to ignite when exposed to an open flame. The flashpoint is the temperature at which the sample momentarily flashes or ignites.
