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 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:

  • Building Materials and Assemblies: Partitions (i.e., office panels), walls, doors, windows and floor/ceiling assemblies, carpeting, wall coverings, acoustical panels and ceiling tiles, duct liner materials and prefabricated silencers (standard size 2’x2’, round, straight, or elbow), recessed lights
