Full Name

ASTM D3154 – Standard Test Method for Average Velocity in a Duct (Pitot Tube Method)


This test method describes measurement of the average velocity of a gas stream for the purpose of determining gas flow in a stack, duct, or flue.

Although technically complex, it is generally considered the most accurate and often the only practical test method for taking velocity measurements.
