Altera can manufacture the Infinity Series Hinged DP Rated French doors to meet ADA requirements and guidelines. The following information delivers a general overview of primary ADA requirements for doors:
ADA REQUIREMENTS OVERVIEW:
Width and Height Requirements:
According to ADA standards, the clear width of a door opening shall have a minimum clear opening of 32 in (815 mm) with the door open 90 degrees, measured between the face of the door and the opposite stop. (Figure 1)
The clear height of a door opening must be a minimum of 80 inches. (Figure 2)
REQUIREMENTS REGARDING DOOR SURFACE:
If there are any projections on the face of the door, they must be no lower than 34 inches above the floor or ground and must not extend more than 4 inches from the surface of the door. (Figure 3)
Door surfaces within 10 inches of the floor or ground must be a smooth surface on the push side extending the full width of the door. Any parts creating a horizontal or vertical joint on the surface shall be within 1⁄16 inch in depth. If cavities are created by added kick plates they must be capped.
HANDLES, PULLS, LOCKS AND LATCHES
Handles, pulls, latches, locks and other operating devices on accessible doors must have a shape that is easy to grasp with one hand and does not require tight grasping, tight pinching, or twisting of the wrist to operate. Lever-operated mechanisms, push-type mechanisms, and U-shaped handles are acceptable designs. When sliding doors are fully open, the operating hardware must still be exposed and usable from both sides. Hardware must be mounted no higher than 48 inches above finished floor.
Thresholds at doorways shall not exceed 3/4 in (19 mm) in height for exterior sliding doors or 1/2 in (13 mm) for other types of doors. Raised thresholds and floor level changes at accessible doorways shall be beveled with a slope no greater than 1:2. If the changes in level are greater than 1⁄2 inch, the threshold must be equipped with a ramp. The floor or ground surface within the maneuvering clearances at the doorway must not have a slope steeper than 1:48.
If a door has a closer, then the sweep period of the closer shall be adjusted so that from an open position of 70 degrees, the door will take at least 3 seconds to move to a point 3 in (75 mm) from the latch, measured to the leading edge of the door.
