Revision of D3154-14 Standard Test Method for Average Velocity in a Duct (Pitot Tube Method)


D3154 was in danger of expiring at the end of 2022 without reapproval. The statement that this "standard is
undergoing revision and will not be ready for ballot before the standard’s expiration date; therefore, it is requested that membership with concerns vote “affirmative with comments”. These comments will be addressed in the revision of this standard. Membership with concerns are also invited to join the revision effort." The renewal ballot received a comment from Mike Brisson stating: "onsiderations for the promised revision:
Section 5 does not actually discuss significance and use but simply says where additional documentation can be found. This section should briefly describe why this standard
is important and how it is used.
In Section 6.6.8, Fyrite is a trademarked name which should be replaced with alternative
wording or identified as the only available option (if that is the case)."

In addition, the 2021 EPA NTTAA Standards Report released June 18, 2021, stated that D3154 was identified as requiring significant revision before it could be used in lieu of government-unique standards (GUS). The report stated the following deficiencies.

Deficiencies: The standard lacks quality control and assurance requirements. It does not include proof that openings of standard pitot tube have not plugged during the test, whether differential pressure gauges other than inclined manometers are used, and the frequency and validity range for calibration of temperature sensors.

The intent of this revision is to address the EPA concerns and the comment received on the renewal ballot.
