ANSI/BHMA A156.3-2014 Grade 1 Standards

Exit devices and panic hardware certification requirements for commercial applications

Last updated: September 25, 2025

Overview

ANSI/BHMA A156.3-2014 is the American National Standard for Exit Devices, developed by the Builders Hardware Manufacturers Association (BHMA). This standard establishes performance requirements, test methods, and operational characteristics for panic hardware and fire exit hardware used in commercial buildings.

Grade 1 certification represents the highest level of durability and performance, requiring products to withstand 500,000 cycles of operation, making them suitable for high-traffic commercial applications where reliability is critical for life safety.

Grade 1 devices are required in many commercial applications, particularly in assembly occupancies, educational facilities, and healthcare buildings where reliable emergency egress is essential.

Grade Requirements

ANSI/BHMA A156.3 defines three grades of performance, with Grade 1 being the highest:

ANSI/BHMA A156.3 Performance Grades
Grade	Cycles Required	Typical Application	Force Requirements
Grade 1	500,000	High-traffic commercial	15 lbs maximum
Grade 2	250,000	Light commercial	15 lbs maximum
Grade 3	100,000	Residential	15 lbs maximum

Grade 1 Specific Requirements

Must maintain consistent performance throughout 500,000 cycles
Operating force cannot exceed 15 pounds at any point during the test
Latchbolt must project at least 1/2 inch when door is closed
Device must operate smoothly without binding or excessive wear
Outside trim must withstand 250,000 additional cycles

Testing Criteria

Cycle Test

The device must complete 500,000 cycles of operation on a test door. Each cycle includes full depression of the touchpad or crossbar, door opening, and return to the latched position. The test is conducted at a rate not exceeding 25 cycles per minute.

Operational Force Test

Maximum 15 pounds force to actuate the device
Force measured at multiple points along the actuating bar
Test performed before and after cycle testing
Force must remain consistent throughout service life

Additional Test Requirements

Finish durability: Salt spray test for 96 hours minimum
Security test: Withstand 250 pound-force pull
Dogging test: 10,000 dogging/undogging cycles if applicable
Temperature test: Operation from 0°F to 120°F
Vertical rod test: 100,000 cycles for top and bottom latches

Applications

Grade 1 exit devices are typically required or recommended for:

High-Traffic Areas

Airport terminals
Convention centers
Sports arenas
Shopping malls
Transportation hubs

Critical Facilities

Hospitals and healthcare
Schools and universities
Government buildings
Data centers
Emergency shelters

Compliance Considerations

When specifying Grade 1 exit devices, consider these compliance factors:

ADA compliance: Maximum 5 pounds operating force for accessibility
Fire rating compatibility: UL 10C listing for fire-rated assemblies
Code requirements: IBC, NFPA 101, and local building codes
Windstorm ratings: Miami-Dade or TDI approval in hurricane zones
Security features: Delayed egress or controlled access options

Always verify local code requirements as they may exceed ANSI/BHMA standards. Some jurisdictions require Grade 1 devices for all commercial applications.
