Scope
This Standard describes methods for evaluating building heating@ ventilation@ air-conditioning@ and refrigeration systems.It applies to air moving and hydronic systems@ including associated air moving@ circulating heat transfer fluid systems@ refrigeration@ electrical power@ and control systems.The Standard includes methods for determining temperature@ enthalpy@ velocity flow rate@ pressure@ pressure differential@ voltage@ amperage@ wattage@ and power factor.This Standard establishes:a. Minimum system configuration requirements to assure that the system can be field tested and balanced.b. Minimum instrumentation required fol field measurements.c. Procedures for field measurements used in testing and in balancing.d. A format of recording and reporting test results for use in evaluating conformance with design requirements.
