Title
Standard Test Methods for Determining Air Leakage of Air Distribution Systems by Fan Pressurization
ASTM International
Publication Date:
Nov 1, 2007
Scope:
The test methods included in this standard are applicable to the
air distribution systems in low-rise residential and commercial
buildings.
These test methods cover four techniques for measuring the air
leakage of air distribution systems. The techniques use air flow
and pressure measurements to determine the leakage
characteristics.
The test methods for two of the techniques also specify the
auxiliary measurements needed to characterize the magnitude of the
distribution system air leakage during normal operation.
A test method for the total recirculating air flow induced by
the system blower is included so that the air distribution system
leakage can be normalized as is often required for energy
calculations.
The proper use of these test methods requires knowledge of the
principles of air flow and pressure measurements.
Three of these test methods are intended to produce a measure of
the air leakage from the air distribution system to outside. The
other test method measures total air leakage including air leaks to
inside conditioned space.
The values stated in SI units are to be regarded as standard.
The values given in parentheses are for information only.
This standard does not purport to address all of the safety
concerns, if any, associated with its use. It is the responsibility
of the user of this standard to establish appropriate safety and
health practices and determine the applicability of regulatory
limitations prior to use. For specific hazard statements, see
Section 7.
