Chapter T8: Other Features

T801 General.  The technical requirements in Chapter T8 shall apply where required by Chapter T2 or where referenced by a requirement in this document.

T802 Surfaces

T802.1 General.  Surfaces shall comply with T802.

Advisory T802.1Surfaces.  The technical requirements for surfaces in T802 apply to circulation paths (T203.4.1), lift platforms (T302.5.1), ramps and bridgeplates (T303.5), wheelchair spaces (T402.2), and step treads (T504.2).

T802.2 Slip Resistant.  Surfaces shall be slip resistant.

T802.3 Openings.  Openings in surfaces shall not allow the passage of a sphere more than 16 mm (5/8 inch) diameter.  Elongated openings shall be placed so that the long dimension is perpendicular to dominant direction of travel.  Lift platforms that are folded and stowed manually, and ramps and bridgeplates that are deployed manually shall be permitted to have a cut-out in the surface 38 mm (1½ inches) maximum by 115 mm (4½ inches) maximum for the operator to grasp the surface.

T802.4 Protrusions.  Protrusions on surfaces shall be permitted to be 6.4 mm (¼ inch) high maximum.

T802.5 Surface Discontinuities.  Surface discontinuities shall be 6.4 mm (¼ inch) high maximum without edge treatment and 13 mm (½ inch) high maximum with beveled edge treatment.  The bevel shall have a slope not steeper than 1:2 (50 percent) applied across the entire surface discontinuity.

T802.5 Surface Discontinuities
Vertical change in level  6.4 mm (1/4 inch) maximum without treatment and vertical change 13 mm (1/2 inch) maximum with a beveled edge sloping 1:2 maximum.

Advisory T802.5 Surface Discontinuities.  Two adjacent surfaces can have discontinuities up to 13 mm (½ inch).  If the surface discontinuity is over 6.4 mm (¼ inch), a bevel with a maximum slope of 1:2 (50 percent) is required, and the bevel must blend the entire surface discontinuity with no lip.

T803 Doorway Lighting.  Lighting at doorways shall comply with Table T803.  Lighting shall not shine directly in the eyes of passengers when entering and exiting doorways.

T804.3.2 Non-Circular Cross Section.  Gripping surfaces with a non-circular cross section shall have a perimeter dimension of 100 mm (4 inches) minimum and 160 mm (6¼ inches) maximum, and a cross section dimension of 57 mm (2¼ inches) maximum.

T804.3.2 Non-Circular Cross Section
Non-circular cross sections (square with rounded corners (a)  and elliptical (b)) shown with the largest cross section dimension 57 mm (2 ¼ inches) long maximum and a perimeter dimension of 100 to 160 mm (4 to 6 1/4 iinches).

T804.4 Clearance.  Clearance between gripping surfaces and adjacent surfaces shall be 38 mm (1½ inches) minimum.

T804.4 Clearance
