scope:

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. 

The field data collected and reported under this standard are intended for use by building designers, operators, and users, and by manufacturers and installers of HVAC systems.

PURPOSE

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.
