Foam Plastic Insulation Testing

Manufacturers of foam plastic insulation are no strangers to innovation. Whether driven by customers seeking novel applications or by the goal of maintaining compliance with ever-changing local, state, and federal requirements, innovative manufacturers maintain close relationships with their third-party testing partners who help them quickly adapt to market needs. These third-party partners help by guiding the manufacturers or validating their plans to ensure the most efficient path to performance and fire-safety compliance.

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 foam plastic insulation tests for many characteristics, including but not limited to:

  • Density
  • Dimensional stability
  • Water absorption
  • Thermal resistance
  • Compressive resistance
  • Water-vapor transmission
  • Oxygen index
  • Closed-cell content
  • Surface burning characteristics
  • Fire performance
  • Tensile strength
  • Leachable chloride, fluoride, silicate, and sodium ions
  • Response to thermal and humid aging

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 foam products:

  • ASTM C271: Standard Test Method for Density of Sandwich Core Materials
