ASHRAE STANDARD Measurement, Testing, Adjusting, and Balancing of Building HVAC Systems
To standardise the measurement, testing, adjusting, balancing, evaluating, and reporting of building heating, ventilating, and air-conditioning systems in the field.
This standard applies to air-moving and hydronic HVAC systems in buildings, as well as their associated heat transfer, distribution, refrigeration, electrical power, and control subsystems.
