Jurisdictions may also modify model codes or standards, so project teams should always verify the requirements adopted by the authority having jurisdiction (AHJ).

    Understanding Codes and Standards for Steel Doors

    The terms code, standard, test standard and listing are sometimes used interchangeably, but they serve different purposes.

    Building Codes

    Building codes establish minimum requirements for the design and construction of buildings. They address areas such as structural safety, fire protection, means of egress, accessibility and occupant safety. The International Building Code (IBC) and other model codes are adopted by jurisdictions throughout the United States, often with state or local modifications.

    Referenced Standards

    Building and fire codes frequently reference other standards for specific products, materials, tests or installation requirements. For example, fire door requirements in building and fire codes may reference NFPA 80 for the installation and maintenance of fire door assemblies.

    Product Standards

    Product standards establish requirements for the construction, materials, performance or installation of specific products. SDI and ANSI/SDI standards provide requirements and guidance specifically related to steel doors and frames.

    Test Standards

    Test standards establish procedures used to evaluate the performance of products or assemblies. Depending on the application, steel doors and frames may be tested for characteristics such as fire resistance, physical endurance, air leakage, windstorm resistance or other performance requirements.

    Listings and Labels

    A listing or label identifies an assembly that has been evaluated in accordance with applicable testing requirements. For rated openings, the complete door and frame assembly must meet the requirements applicable to the specific application.

    How to Specify Steel Doors Using Codes & Standards

    1. Identify the Applicable Building Codes

    Determine which building, fire, accessibility and energy codes have been adopted by the project jurisdiction. Check for state and local amendments that may modify the model code requirements.

    2. Identify the Opening’s Function

    Determine how the opening will be used and what conditions it will encounter. Consider factors such as occupancy, location, means of egress, fire protection, accessibility, security, acoustics and environmental exposure.

    3. Determine Required Performance

    Identify the required rating or performance level before selecting the door and frame. A fire-rated opening, for example, has different requirements from an exterior opening subject to severe windstorm conditions or a security opening.

    4. Select the Appropriate Steel Door & Frame

    Use applicable SDI standards and project requirements to select the appropriate door level, construction, frame type, hardware preparation and other characteristics. ANSI/SDI A250.8 provides a foundation for specifying standard steel doors and frames.

    5. Coordinate the Complete Opening

    The door should be coordinated with the frame, hardware, glazing, louvers, anchors, accessories and surrounding wall construction. Performance requirements apply to the complete opening assembly, not simply the door itself.

    6. Reference the Applicable Standards

    Include the applicable SDI, ANSI, NFPA, UL, ASTM and other standards in the project specification. Avoid relying only on generic descriptions such as “heavy-duty” or “fire-rated” when specific performance requirements can be identified.

    7. Verify Jurisdictional Requirements

    Confirm applicable requirements with the authority having jurisdiction (AHJ), particularly when a model code has been modified or supplemented by state or local requirements. Project-specific code compliance should be verified by the appropriate design and construction professionals.
