"Method of Testing the Performance of Air Outlets and Air Inlets"
Field technicians use this factor with balometers or anemometers to calculate actual CFM (Cubic Feet per Minute) during the Testing, Adjusting, and Balancing (TAB) phase of a project. 3. Laboratory Setup and Instrumentation Requirements
ASHRAE also provides "Read-Only" access to several of its standards via its online public preview portal. This allows engineers and students to reference the technical content without purchasing a full PDF license, provided they do not need to print or copy the text.

ASHRAE often provides free, read-only digital access to standards referenced in building codes on their official website. To help me tailor any further technical details, tell me:
: Guidance for displacement ventilation draft risk assessment. Normative Appendix F "Method of Testing the Performance of Air Outlets
: Covers a broader range of air-device types and sizes, including displacement ventilation and underfloor outlets .
The standard specifies the dimensions and baffling of the supply plenum to ensure an even, non-turbulent approach velocity to the test device.
Modern building codes (such as ASHRAE Standard 90.1) and green building certification systems (like LEED) mandate strict indoor environmental quality (IEQ) criteria. Standard 70 data helps engineers accurately model spaces to avoid drafts, uneven temperatures, and excessive noise. Prevention of Air Distribution Failures This allows engineers and students to reference the
