Ametek Chatillon Occupational Testing

ADA Compliance Testing

Chatillon dynamometers may be used to measure and evaluate compliance to the Americans with Disabilities Act requirements.

Door Opening Force

Chatillon dynamometers are used verify, validate and test structures and components relative to the American's with Disabilities Act specifications and requirements.

4.13.11* Door Opening Force

The maximum force for pushing or pulling open a door shall be as follows:

  • Fire doors shall have the minimum opening force allowable by the appropriate administrative authority.
  • Other doors.
    • exterior hinged doors: (Reserved)
    • interior hinged doors: 5 lbf (22.2N)
    • sliding or folding doors: 5 lbf (22.2N)

These forces do not apply to the force required to retract latch bolts or disengage other devices that may hold the door in a closed position.

Automatic Doors and Power Assist Door Force

Chatillon dynamometers are used verify, validate and test structures and components relative to the American's with Disabilities Act specifications and requirements.

4.13.12* Automatic Doors and Power-Assisted Doors

If an automatic door is used, then it shall comply with ANSI/BHMA A156.10-1985. Slowly opening, low-powered, automatic doors shall comply with ANSI A156.19-1984. Such doors shall not open to back check faster than 3 seconds and shall require no more than 15 lbf (66.6N) to stop door movement. If a power-assisted door is used, its door-opening force shall comply with 4.13.11 and its closing shall conform to the requirements in ANSI A156.19-1984.

Grab Bar Bending Stress

Chatillon dynamometers are used verify, validate and test structures and components relative to the American's with Disabilities Act specifications and requirements.

4.26.3 Structural Strength

The structural strength of grab bars, tub and shower seats, fasteners, and mounting devices shall meet the following specification:

  • Bending stress in a grab bar or seat induced by the maximum bending moment from the application of 250 lbf (1112N) shall be less than the allowable stress for the material of the grab bar or seat.

Grab Bar Shear Force

Chatillon dynamometers are used verify, validate and test structures and components relative to the American's with Disabilities Act specifications and requirements.

4.26.3 Structural Strength

The structural strength of grab bars, tub and shower seats, fasteners, and mounting devices shall meet the following specification:

  • Shear force induced in a fastener or mounting device from the application of 250 lbf (1112N) shall be less than the allowable lateral load of either the fastener or mounting device or the supporting structure, whichever is the smaller allowable load.
