Independent Testing Agency (ITA)
A Division of Building Envelope Consulting Services, LLC

Independent Testing Agency is a subsidiary of BECS to specifically provide the quality assurance air & water infiltration field testing services specified in the construction industry at a great value.

We reference voluntary specification and performance guidelines outlined by the American Architectural Manufacturers Association (AAMA 101, 501, 502, and 503) which in turn refer to the American Society for Testing and Materials (ASTM) Standards for field evaluation.  Below is the list of ASTM standards that we utilize during our quality control evaluation of field conditions:

  • ASTM E 783 - Standard Test Method for Field Measurement of Air Leakage Through Installed Exterior Windows and Doors.

    • The test method is applicable to exterior windows and doors and is intended to measure only such leakage associated with the assembly and not the leakage through openings between the assemblies and adjacent construction.

  • ASTM E 1105 - Standard Test Method for Field Determination of Water Penetration of Installed Exterior Windows, Skylights, Doors, and Curtain Walls, by Uniform or Cyclic Static Air Pressure Difference.
    • The test method is applicable to any curtain wall area or to windows, skylights, or doors alone.  It is intended primarily for determining the resistance to water penetration through such assemblies for compliance with specified performance criteria, but it may also be used to determine the resistance to penetration through joints between the assemblies and the adjacent construction.  This standard simulates a wind driven rainstorm.
