Frequently Asked Questions of Questions Regarding Product Evaluations

FAQ Index

General

  1. Is there a fee for having building products evaluated by TDI? TDI does not charge a fee for evaluating a product.
  2. Why doesn't TDI rely on products that have been evaluated by the ICC evaluation service, the Florida Product Approval System, or by Dade County, FL rather than developing their own reports?
    There are several reasons. First, not all of the building products that have been evaluated by TDI have also been evaluated by the ICC evaluation service, the Florida Product Approval System, or by Dade County, Florida. If we relied exclusively on products that have been evaluated by these organizations, then the availability of certain products may be limited. Second, windows, glass doors, and skylights, that have been evaluated by Dade County, FL. are not tested and labeled as required in Section R613.4 and R613.7.1 of the International Residential Code (IRC) and Section 1714.5.1 of the International Building Code (IBC) for windows and glass doors and in Sections R308.6.10 and R308.6.12.1 of the Texas Revisions to the IRC, Section 2405.5 of the IBC, and in Section 2405.7.1 of the Texas Revisions to the IBC for skylights.
  3. Will TDI evaluate products that have been evaluated by the ICC evaluation service, by the Florida Product Approval System, or by Dade County, FL?
    TDI will review product information for many products that other organizations have already evaluated. Before developing an evaluation report, the TDI will first determine if the product meets the adopted building specifications. The TDI will not be able to evaluate a product that has been tested to the Dade County, FL criteria if it is not able to comply with Sections R613.4 and R613.7.1 of the IRC or Section 1714.5.1 of the IBC for windows and glass doors or Sections R308.618 and R308.6.12.1 of the Texas Revisions to the IRC, Section 2405.5 of the IBC, and Section 2405.7.1 of the Texas Revisions to the IBC for Skylights.
  4. Are Texas licensed professional engineers who are appointed by TDI as qualified inspectors required to use product evaluation reports developed by the TDI on structures they are certifying?
    No. The engineer appointed as a qualified inspector may use information, such as test reports and design drawings provided by the product manufacturer or code evaluation reports, to determine if a product meets the required adopted building specifications and the design requirements for the structure.
  5. What design pressure should I test my product to resist?
    Please refer to Tables R301.2(2) and R301.2(3) of the IRC or ASCE 7-05. Products tested in accordance with ASTM E 330-02 must be tested to 1.5 times the design pressure.
  6. In areas that require windborne debris protection, do you require that we test exterior wall coverings, such as vinyl siding, for windborne debris resistance?
    No. Windborne debris protection is only required for exterior opening products such as windows, exterior doors, garage doors, skylights. Please refer to the Texas Revisions for specific windborne debris requirements.
  7. Are windows, doors, garage doors, and skylights required to be windborne debris resistant in the Inland II zone?
    No. In the Inland II zone, there are no requirements for windborne debris. Please refer to the Texas Revisions for specific windborne debris requirements.
  8. Are windows, doors, garage doors, and skylights required to be windborne debris resistant in the Inland I zone?
    In the Inland I zone, on all new construction, additions, renovations, repairs, you must provide protection on all glazed openings from windborne debris. This means that windows, skylights, doors with glazing, and garage doors with glazing must be either windborne debris resistant or protected from windborne debris with an impact protective system (shutter). Please refer to the Texas Revisions for specific windborne debris requirements.
  9. Are windows, doors, garage doors, and skylights required to be windborne debris resistant in the Seaward zone?
    In the Seaward zone, on all new construction, additions, renovations, and repairs, you must provide protection on all exterior openings from windborne debris. This means that windows, skylights, doors, and garage doors must be either windborne debris resistant or protected from windborne debris with an impact protective system (shutter). Please refer to the Texas Revisions for specific windborne debris requirements.
  10. Where can I have my building products tested?
    Building products must be tested at independent testing facilities recognized by either (1) the International Code Council; (2) the American Architectural Manufacturers Association (AAMA); (3) the Window and Door Manufacturers Association (WDMA); (4) Dade County, FL; (5) Underwriters Laboratories (UL); (6) Factory Mutual (FM); or (7) TDI.
  11. If I test a product windborne debris resistance, does it also need to be tested for uniform static pressure resistance?
    Yes. Refer to FAQs for windows, doors, garage doors, skylights, and impact protective systems for specific requirements.
  12. What standards for windborne debris will TDI accept?
    TDI will accept, for review, test reports for building products that have been tested in accordance with either: (1) ASTM E 1886-04 and ASTM E 1996-04; (2) AAMA 506-00; or (3) ANSI/DASMA 115-203 for garage doors, or (4) Dade County, FL TAS-201, TAS-202, and TAS-203 (except for windows and glass doors that must comply with the testing and labeling criteria specified in Section R613.4 and R613.7.1 of the IRC and Section 1714.5.1 of the IBC and for skylights that must comply with the testing and labeling criteria specified in Section R308.612.1 of the Texas Revisions to the IRC and Section 2405.7.1 of the Texas Revisions to the IBC).

  16. If a building product is not listed on TDI's product evaluation index, then does that mean that the product is not acceptable?
    No. It may only mean that TDI has not evaluated the product because we have not received any information from the product manufacturer. It's possible that the product meets the building specifications TDI adopted. If you are interested in using a product that is not listed on our index, and the product installation will be inspected by a TDI windstorm field inspector, please contact the TDI prior to purchasing the product. We may be able to obtain the appropriate test data from the product manufacturer and provide it to our inspectors. If a Texas licensed professional engineer who is appointed by the TDI as a qualified inspector will be inspecting the product installation, then the engineer can obtain the appropriate test data directly from the product manufacturer and can determine if the product complies with the building specifications TDI adopted.
  17. Are building products that are installed on commercial buildings required to meet TDI's requirements?
    If the Texas Windstorm Insurance Association will insure the commercial structure for windstorm and hail insurance, then all of the commercial structure's installed building products subject to wind loads should comply with the building specifications TDI adopted.
  18. When is the small missile impact test required?
    Please refer to ASTM E 1886-04 and ASTM E 1996-04. For impact protective systems (shutters), the test is required if there are openings greater than 3/16 inch projected horizontally. For exterior opening systems (windows, doors, skylights), the test is required when the products will be installed greater than 30 feet above grade (Note: for exterior opening systems, the small missile test is not required if the exterior opening product has passed the large missile test).
  19. If I am testing my product for windborne debris resistance, how many specimens must I test?
