To provide uniform procedures for measurement, testing, adjusting, balancing, evaluating, and reporting the performance of building heating, ventilating, and air-conditioning systems in the field.
This standard applies to building heating, ventilating, and air-conditioning (HVAC) systems of the air-moving and hydronic types and their associated heat transfer, distribution, refrigeration, electrical power, and control subsystems.

This standard includes
a. methods for determining thermodynamic, hydraulic, hydronic, mechanical, and electrical conditions;
b. methods for determining room air-change rates, room pressurization, and cross contamination of spaces;
c. procedures for measuring and adjusting outdoor ventilation rates to meet specified requirements; and
d. methods for validating collected data while considering system effects.

This standard establishes
a. minimum system configuration requirements to ensure that the system can be field tested and balanced;
b. minimum instrumentation required for field measurements;
c. procedures for obtaining field measurements in HVAC testing and balancing and equipment testing; and
d. formats for recording and reporting results.
