Air/Water/Structural Assembly Testing

Most building products are designed to work together with other complementary products to actuate their benefits entirely. Customers expect that these building products will function as specified when appropriately installed, even if the combination of all components is beyond each manufacturer’s control. For assurance, code compliance, and to fulfill specifications, manufacturers of individual building components find that testing the air, water, and structural performance of assemblies provides the answers they need to excel in their business.

ICC NTA laboratories are accredited to the ISO 17025 standard, which ensures that you and your customers can rely on the validity of our results. Our team also understands how important test results are for your business goals and objectives — all our team members work together with you to efficiently conduct tests and prepare the test reports you need. We conduct assembly tests for various products and purposes, including but not limited to:

  • Floors, such as cantilevered floor assemblies
  • Proof loads, ultimate loads
  • Roofs, such as diaphragms, assemblies resisting wind loads, and assemblies including the building envelope
  • Trusses
  • Verification testing, on-site or in-situ
  • Walls, such as shear walls, assemblies resisting wind or gravity loads, and assemblies including the building envelope

As part of the International Code Council Family of Solutions, we work directly with ICC Evaluation Service, LLC (ICC-ES) to create tailored test plans that capture specialized requirements for innovative products, such as those found in the ICC-ES Acceptance Criteria. Test plans help ensure your innovative product has a clear path through the certification process with agreement from all participants. Below is a list of standards that may be included in test plans for Structural Assembly testing:

  • ASTM D198: Standard Test Methods of Static Tests of Lumber in Structural Sizes
  • ASTM D4761: Standard Test Methods for Mechanical Properties of Lumber and Wood-Based Structural Materials
  • ASTM D5206: Standard Test Methods for Windload Resistance of Rigid Plastic Siding
  • ASTM D5055: Standard Specification for Establishing and Monitoring Structural Capacities of Prefabricated Wood I-Joists
  • ASTM D5456: Standard Specification for Evaluation of Structural Composite Lumber Products
  • ASTM E72: Standard Test Methods of Conducting Strength Tests of Panels for Building Construction
  • ASTM E283: Standard Test Method for Determining Rate of Air Leakage Through Exterior Windows, Skylights, Curtain Walls, and Doors Under Specified Pressure Differences Across the Specimen
  • ASTM E330: Standard Test Method for Structural Performance of Exterior Windows, Doors, Skylights and Curtain Walls by Uniform Static Air Pressure Difference
  • ASTM E331: Standard Test Method for Water Penetration of Exterior Windows, Skylights, Doors, and Curtain Walls by Uniform Static Air Pressure Difference
  • ASTM E564: Standard Practice for Static Load Test for Shear Resistance of Framed Walls for Buildings
  • ASTM E1592: Standard Test Method for Structural Performance of Sheet Metal Roof and Siding Systems by Uniform Static Air Pressure Difference
