ANSI / BHMA — Builders Hardware Manufacturers Association (A156 Series)
BHMA develops voluntary consensus standards for architectural hardware through the ANSI accreditation process. The A156 series is the definitive US standard for door hardware performance and testing. Standards are published by BHMA and available at buildershardware.com. ANSI approval is indicated in the full designation (e.g., ANSI/BHMA A156.1-2023).
ANSI/BHMA A156.1 Core Standard
Butts and Hinges
The primary US standard for butt hinges. Defines three performance grades (Grade 1, 2, 3), cycle-life testing requirements (500,000 cycles for Grade 1), leaf thickness, load capacity, and dimensional tolerances. Any hinge used in a commercial application should meet A156.1 Grade 1 or Grade 2 at minimum.
ANSI/BHMA A156.7
Template Butt Hinges
Governs template hinges — hinges whose screw-hole patterns match the standard SDI/ANSI template punch pattern used in factory-prepared hollow metal doors and frames. Template hinges enable direct field installation without custom drilling. This standard defines the exact hole locations, tolerances, and required documentation to claim template compliance.
ANSI/BHMA A156.17 Self-Closing
Self-Closing Hinges
The only ANSI standard that specifically addresses self-closing hinges (both spring and hydraulic/fluid-damped types). Defines closing force requirements, cycle-life testing (500,000 cycles for Grade 1), and adjustment range specifications. Products claiming ADA compliance with self-closing hinges should reference both A156.17 and the ADA opening force limits (5 lbf maximum for interior doors).
ANSI/BHMA A156.26 Continuous
Continuous Hinges (Piano Hinges)
Covers continuous hinges that run the full height of the door, distributing load across the entire door edge rather than at discrete points. Often used in high-traffic commercial and institutional applications to eliminate sagging. Defines geared and non-geared types, load ratings, cycle life, and corrosion resistance requirements.
ANSI/BHMA A156.4
Door Controls — Closers
The primary standard for overhead door closers. Relevant to hinge selection because A156.4 and A156.17 sometimes govern the same installation — a project may choose between an overhead closer (A156.4) or a self-closing hinge (A156.17) as the required closing device. A156.4 also defines the ADA-relevant backcheck and sweep speed requirements.
ANSI/BHMA A156.18
Materials and Finishes
Defines the standardized US finish code system (e.g., US32D = satin stainless steel, US10B = oil-rubbed bronze). Also establishes salt spray corrosion testing hours required for each finish category. Essential for specifying hardware finishes consistently across multiple hardware types and manufacturers.
ANSI/BHMA A156.2
Bored and Preassembled Locks and Latches
While not a hinge standard, A156.2 governs the locksets that work in conjunction with hinges on commercial doors. Relevant because latch engagement — which affects fire door closing requirements — is tested under this standard. Grade 1 locks are required on fire-rated assemblies per most AHJ interpretations.
NFPA — National Fire Protection Association
NFPA develops fire safety codes and standards adopted by most US jurisdictions. NFPA documents are updated on 3–5 year cycles and are available for free online viewing (with registration) at nfpa.org or for purchase in print or PDF. The Authority Having Jurisdiction (AHJ) determines which edition is enforced locally.
NFPA 80 Core Standard
Standard for Fire Doors and Other Opening Protectives
The primary authority for all fire-rated door assemblies in the US. Covers requirements for hinges (Table 6.4.3.1 — minimum hinge size and quantity), closing devices, latching, glazing, gasketing, and annual inspection/testing. Every fire door hinge selection must comply with NFPA 80. The 2025 edition is the most recent; many jurisdictions enforce the 2019 or 2022 editions.
NFPA 101
Life Safety Code
The Life Safety Code governs egress and occupancy requirements that directly affect door hardware selection — which doors must be self-closing, which must be fire-rated, and where panic hardware (push bars) is required. Hinges on egress doors must not impede the required clear opening width. Referenced alongside NFPA 80 for fire door assemblies.
NFPA 105
Standard for Smoke Door Assemblies and Other Opening Protectives
Governs smoke door assemblies — doors tested for smoke leakage rather than flame and heat resistance. Smoke doors require self-closing devices, positive-latching hardware, and smoke-gasketing. The hinge requirements generally parallel NFPA 80 but the assembly listing and testing protocol differ. Many corridors in healthcare and education facilities require smoke-rated assemblies under NFPA 105.
UL — Underwriters Laboratories (Now UL Solutions)
UL is an independent safety testing and certification laboratory. UL Listings on door hardware indicate the product has been tested to the relevant UL standard and is authorized to carry the UL mark. For fire doors and hardware, a UL Listing is required by NFPA 80. Standards are available at ul.com/standards.
UL 10C Core Standard
Standard for Positive Pressure Fire Tests of Door Assemblies
The more stringent of the two UL fire door test standards. UL 10C simulates real fire conditions where hot gases are positively pressurized against the door — the worst-case scenario in a stairwell or mechanical shaft. All hardware (including hinges) in a UL 10C listed assembly must be listed as part of that assembly. Most new commercial construction requires UL 10C listings.
UL 10B
Standard for Fire Tests of Door Assemblies
The predecessor to UL 10C, still in use for some assembly types. Tests doors under neutral pressure (no positive pressure differential). Some older listed assemblies reference UL 10B. When specifying hardware for renovation projects, verify whether the existing door listing is UL 10B or UL 10C — replacement hardware must be compatible with the existing listing.
UL 305
Standard for Panic Hardware
Governs panic hardware and exit devices used on egress doors. Indirectly relevant to hinges because the hinge must support doors with heavy panic device loads and must not impede the door's travel to the required 90-degree minimum opening. Listed panic hardware used on fire-rated doors must be combined with listed hinges.
ICC — International Code Council
The International Code Council (ICC) develops model building codes adopted (with local amendments) by most US states and municipalities. The I-Codes are updated on a 3-year cycle. Adopted editions vary by jurisdiction. Available at iccsafe.org.
IBC — International Building Code Core Standard
International Building Code
The IBC is the foundational building code for commercial construction in the US. Chapter 7 (Fire and Smoke Protection) and Chapter 10 (Means of Egress) directly govern door hardware. The IBC references NFPA 80 for fire door assemblies and ICC A117.1 for accessibility. Door hardware must comply with IBC requirements as adopted and amended by the local jurisdiction.
ICC A117.1 Accessibility
Accessible and Usable Buildings and Facilities
The technical accessibility standard referenced by both the IBC and the ADA Standards for Accessible Design. For door hardware, A117.1 specifies: maximum opening force (5 lbf for interior non-fire doors), clear width requirements (32″ minimum, 34″ preferred), door hardware operability (lever-style or push/pull, no tight grasping or twisting), and maneuvering clearances. Self-closing hinge selection must comply with the 5 lbf limit.
IRC — International Residential Code
International Residential Code
Residential counterpart to the IBC. The IRC governs door construction and hardware for single-family homes and duplexes. Requirements are less stringent than the IBC — residential doors typically require fire separation between garage and living space (20-minute rated assemblies with self-closing hardware), but commercial-grade listings are not required for most residential applications.
ADA / DOJ — Americans with Disabilities Act / Department of Justice
The ADA is federal law (enforced by the Department of Justice) that prohibits discrimination based on disability. The 2010 ADA Standards for Accessible Design are the legally enforceable requirements for most commercial and public accommodation facilities in the US. The technical detail in the ADA Standards is largely drawn from ICC A117.1.
2010 ADA Standards for Accessible Design Federal Law
ADA Standards for Accessible Design (2010)
The 2010 ADA Standards are the governing federal requirements for accessible design. Section 404 addresses doors and doorways: minimum 32″ clear width, 5 lbf maximum opening force for interior non-fire doors, hardware operability requirements, and maneuvering clearance dimensions. Self-closing hinges used in ADA-compliant installations must open within the 5 lbf limit and must not close before the user has cleared the door opening.
Section 508 — Rehabilitation Act
Section 508 Standards (Federal Electronic and Information Technology)
While primarily governing electronic and information technology, Section 508 also applies to federally funded building projects. Federal buildings, VA hospitals, and federally funded educational facilities must comply with both ADA Standards and Section 508 requirements. Door hardware specifications for federal projects should reference both documents.
