Acoustical Testing

Intertek can assist with all facets of acoustical testing, helping you meet third-party acoustical and airflow performance requirements defined by specifiers, buyers, and regulatory authorities.

Turnaround times for many of our tests are less than one week from receipt of sample to issuing of test report.

We offer a wide range of acoustical, airflow, and leakage testing services on products like air conditioners, dishwashers, windows and doors. Our acoustical testing facilities are NVLAP Acoustical Testing Services accredited for ASTM C423, ASTM E 90, ASTM E 477, ASTM E 492, ANSI S12.31, ANSI S12.32 and ANSI S12.51. Our acoustical and airflow testing laboratory is one of the most extensive and diversified facilities of its kind.

Association Testing: We test according to Air-Conditioning, Heating, and Refrigeration Institute (AHRI) and Air Movement and Control Association (AMCA) program requirements.

Leakage Testing: We perform leakage testing on several different product types including recessed lighting, air handler cases, PTACs, and others.

ENERGY STAR® Noise Rating: We test to ENERGY STAR Noise Rating standards as well as several different vibration measurement standards.

Product Development Assistance: We can conduct testing characterizing the sound and airflow performance of alternate components and designs.

Field Tests and Verifications: We perform many types of field tests and verifications, including: FIIC, ASTC, NIC, NNIC, Sound Power, Sound Pressure, and Sound Intensity.

Our floor ceiling assemblies include 6” concrete, 6” concrete with ceiling plenum, and a 100 sq. ft. floor opening for custom floor/ceiling systems to ASTM and ISO. The 6” concrete is also used for Delta IIC measurements.

Examples of products we test include:

Mechanical Equipment and Accessories: Outdoor unitary air conditioning equipment, ducted and non-ducted indoor air conditioning equipment, grilles, registers and diffusers, air control and distribution devices, fans, blowers and other air moving devices, machines, mechanical and electrical equipment and sub-assemblies; and hand-held power tools
