We have been asked on numerous occasions to audit Exeloo’s and are yet to find one that meets the requirements of both the BCA & AS1428.1.
The following is an extract from a recent audit we undertook.
Access approach path measured at 1:7.5. Maximum allowed 1:8.
Insufficient contrast between walls and door in accordance with AS1428.1 7.1(f)
Flat level section not provided in front of door controls.
Physical Specifications for Braille – Australian Braille Authority
Braille characters are composed of combinations of dots from a matrix of three rows and two columns, known as a cell.
The physical specifications for Braille dots and the distance between them shall be as follows:
Note I: within cells the horizontal distance between dots must always be less than or equal to the vertical distance between them.
Note II: Braille dots should be smooth and pleasant to touch. Therefore, dots must be dome shaped, rather than being pointy or flat. Note that the spherical radius is a function of the base diameter and the height of dots, not an independent parameter.
This Specification sets out the requirements for the design and installation of Braille and tactile signage.
2.1 Location of Braille and tactile signs
Signs including symbols, numbering and lettering must be designed and installed as follows:
a) Signs must be located not less than 1200 mm and not higher than 1600 mm above the floor or ground surface.
b) Signs with single lines of characters must have the line of tactile characters not less than 1250 mm and not higher than 1350 mm above the floor or ground surface.
c) Signs identifying rooms containing features or facilities listed in D3.6 must be located
(i.) on the wall on the latch side of the door with the leading edge of the sign located between 50 mm and 300 mm from the architrave; and
(ii.) in the event of insufficient latch side dimension, a sign may be placed on the non-latch side of the door; and
(iii.) where (i) or (ii) is not possible, the sign may be placed on the door itself.
d) Signs identifying paths of travel must be placed so they are located directly ahead in the direction of travel. Where one wall continues in the direction of travel and the other forms a corner, the sign must be placed on the continuing wall.
2.2 Braille and tactile sign specification
The following applies to Braille and tactile sign orientation:
a) Tactile characters must be raised or embossed to a height of not less than 1 mm and not more than 1.5 mm.
b) Characters must have a height of not less than 17.5 mm for each metre of viewing distance.
c) Upper case tactile characters must have a height of not less than 15 mm and not more than 55 mm.
d) Lower case tactile characters must have a height of 50% of the related upper case characters.
e) Tactile characters, symbols, and the like, must have rounded edges.
f) The entire sign, including any frame, must have all edges rounded.
g) The surface of the sign must be continuous for hygiene purposes.
h) Signs must be constructed so as to resist the removal of letters and Braille dots by picking or adhesive failure.
i) The background, negative space or fill of signs must be of matt or low sheen finish.
j) The characters, symbols, logos and other features of signs must be matt or low sheen finish.
k) The minimum letter spacing of tactile characters on signs must be 2 mm.
l) The minimum word spacing of tactile characters on signs must be 10 mm.
m) Fonts with letters of constant stroke thickness must be used.
n) The thickness of letter strokes must be not less than 2 mm and not more than 7 mm.
o) Tactile text must be left justified, except that single words may be centre justified
The following applies to luminance-contrast as defined in AS 1428.1:
a) The backgrou`nd, negative space or fill of a sign or border must have a minimum luminance-contrast with the surface on which it is mounted of 30%.
b) A border must be provided for luminance-contrast with the sign’s background and shall have a minimum width of 5 mm.
c) Tactile characters, icons and symbols must have a minimum 30% luminance-contrast with their background or fill within the sign.
d) Luminance-contrasts must be met under the lighting conditions in which the sign is to be located.
Braille and tactile signs must be illuminated to ensure luminance-contrast requirements are met at all times during which the sign is required to be read.
The following applies to Braille:
a) Braille must be grade 1 Braille (uncontracted) in accordance with the criteria set out by the Australian Braille Authority.
b) Braille must be raised and domed.
c) Braille must be located 8 mm below the bottom line of text (not including descenders).
d) Braille must be left justified.
e) Where an arrow is used in the tactile sign, a small arrow must be provided for Braille readers.
f) On signs with multiple lines of text and characters, a semi-circular Braille locator at the left margin must be horizontally aligned with the first line of Braille text.
