Not everyone knows the critical hinge code that might affect the safety and functionality of the door operation. Choosing the right quality is what needs to be done especially if you’re working with fire rated, ADA compliant, or high-traffic doors—but first what are the key codes to understand?
3 Key Hinge Code Explained
1) ANSI/BHMA A156.17
This standard outlines requirements for cycle testing, materials, finishes, and dimensions. For single-acting hinges, Grade 1 certification means passing a rigorous 1,000,000-cycle durability test. This ensures long-term reliability with minimal maintenance or replacement.
Single Acting Hinges | |
*Cycles | Number |
Grade 1 | 1,000,000 |
Grade 2 | 500,000 |
Grade 3 | 250,000 |
*Cycle requirement on BHMA A156.17 Standard
2) ADA Door Closing Speed and California CBC 2016 (1126A.4.2)
Some doors may shut quickly making it difficult for disabled personnel to get through safely. Both the ADA and the CBC hinge code helps to provide accessibility to everyone by requiring:
- Doors with closers should take at least 5 seconds to move from the open position at 90 degrees to 12 degrees from the latch.
- Doors with spring hinges should take at least 1.5 seconds to close from the open position of 70 degrees.
3) NFPA 80 Standard
This standard defines the minimum requirements for fire doors, curtains, dampers, and other opening protectives to function properly in fire conditions. It aims to protect life and property by ensuring correct installation, inspection, and maintenance. To comply, doors and components must be made of fire-resistant materials and be UL-listed or labeled by an approved testing agency to verify performance under fire exposure.
The Problem with Traditional Spring Hinges
Most traditional spring hinges don’t pass the hinge code—Why?
- No adjustable closing speed: they slam shut quickly, which violates ADA and CBC code that require doors to take at least 1.5 seconds to close from 70°.
- Not built for long-term durability: wear out faster, requiring more maintenance or replacement because they fail to meet the 1million cycle test.
- Poor material and non fire rated: often made from material that can’t withstand high heat, not UL-listed.
- Uncontrolled and Non-Adjustable: lack of adjustability for tension or damping causing doors to have an inconsistent performance, especially in high-traffic environments.

The minimum closing force for a fire door closer is 5 lbf (22 N) at the leading edge. This ensures the door reliably latches, meeting NFPA 80 fire door requirements and ADA accessibility standards.
To stop a door from closing on its own, adjust the hinge tension until the door stays in place or closes as desired.
