Air system testing and reporting shall be performed in accordance with instrumentation and procedures as defined within the 2005 Seventh Addition Procedural Standards for Testing, Adjusting and Balancing of Environmental Systems.

Instrumentation

All air system testing and balancing shall be performed with instrumentation in compliance with guidelines identified within the NEBB procedural standards. Selection of specific instrumentation for each application will be made to secure maximum accuracy level of test data. Listing of specific instrumentation and calibration records shall be submitted with final test report.

SOUND TEST PROCEDURES

Sound testing and reporting shall be performed in accordance with instrumentation and procedures as defined within the 1994 NEBB Procedural Standards for the Measurement and Assessment of Sound & Vibration.

Instrumentation

All sound tests will be performed with a CESVA Model SC310, it can
work as a type-1 integrating-averaging sound level meter that complies
with IEC 60651, IEC 60804 AND IEC 61672 International Standards and
their EU counterparts EN 60651 and EN 60804. The SC310 also complies
with the American standards ANSI S1.4 and ANSI S1.43. We always
carry the CESVA CB-5 calibrator or
a "GEN-RAD" Model 1982 Precision Sound Level Meter and Octave Ban Analyzer. This instrument conforms to ANS1 S1.4 Type 1 and 1EC 179 and is ideal for ASHA compliance measurements. We carry a "GEN-RAD" model 1562A Calibrator with the instrument at all times and meter calibration is verified before performing sound level testing.

Timing

Sound level measurements will be performed when the space is relatively quiet with a minimum of activity and background noise.

Specific Test Procedures

The microphone will be positioned no closer than three feet from any floor, wall or ceiling, or no closer than six feet from any terminal or room unit.

Sound pressure levels will be tested as prescribed in project specifications.

Reports

The following data shall be included on final report:

1. Measurements at the specified frequencies with the tested equipment turned on.
2. Measurements at the specified frequencies with the tested equipment turned off.
3. Corrective calculation, if required, between equipment noise and ambient noise levels.
4. The "Equipment Components" of the room sound level.
5. Graphical representation of equipment component, if required.
6. Identification of test location.

BUILDING SYSTEMS COMMISSIONING

All procedures and reporting shall be performed in accordance with procedures as defined within the NEBB Procedural Standards for Building Systems Commissioning of Environmental Systems, and Project Specifications.
