TECHNICAL INFORMATION

PERMANENT ROOM IDENTIFICATION SIGNS
(using separate tactile and visual characters)

Signs that designate permanent rooms and spaces must comply with specifications listed in the rest of this summary, with the following exceptions:

Sample Combination 2-Part Visual / Tactile Room Sign:

TACTILE CHARACTER EXCEPTIONS:

Where separate raised letters and visual characters with the same information are provided, tactile characters must meet all criteria listed on pages, Material Finish and Color Contrast and Tactile Characters, except:

• The raised character height (tactile characters) is permitted to be 1/2 inch (13 mm) minimum.

• Tactile characters are not required to contrast with the background.

Combination 2-part visual / tactile signs allow for greater flexibility regarding the use of type fonts for the visible portion, but require more surface area for repeating the visual information in a tactile form.

VISUAL CHARACTERS EXCEPTIONS:

Where separate raised letters and visual characters with the same information are provided, visual characters must meet all criteria listed on pages, Material Finish and Color Contrast and Tactile Characters, except:

• Visual only characters can be uppercase or lowercase or a combination of both.

• Type style can be serif or sans serif. However, they may not be italic, oblique, script, or highly decorative in form.

• Stroke thickness (based on uppercase "I"). 10% minimum and 30% maximum of character height.

• Character Spacing: 10% minimum and 35% maximum of character height.

• Character Height: sized to viewing distance (see page, Minimum Character Heights for Visual Signs).
