The work of preparing International Standards is normally carried out through ISO technical committees
10、. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the Intern
11、ational Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the diffe
12、rent types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2. www.iso.org/directivesAttention is drawn to the possibility that some of the elements of this document may be the subject of patent rights.

22、raille patterns or a combination of braille patterns; the braille word is composed of one or more braille characters.Braille patterns are all placed within the braille cell and they require the space of the braille cell. A braille cell requires the space of all six nominal dots. Vacant dots shall no
23、t be neglected because they are a part of the braille pattern.Where a braille character or word appears in isolation, there shall be an exclusion zone around such a character or word.Codes and format of braille characters, which are commonly used and recognized in each country, shall be adopted.Brai
24、lle shall be arranged to allow tactile reading to be performed consistent with the braille reading order in the language in which it is presented, e.g. left to right.3.2 Configuration and spacing of braille dot and cellThe configuration of braille dots and cells shall be in accordance with Figure 1;
25、 the spacing shown as a, b, p and q shall be in the range shown in Table 1.Specifications should be in line with national or regional standards, if applicable.Table 1 Spacing between braille dots and cellsDimensions in millimetresParameters DescriptionDistance between dot centresa Vertical dot spaci

31、e perpendicular height of braille dot centre, h, should be greater than 0,5 mm when used in outdoor arrangement and on or in vehicles of means of transport.3.5 Correlation among dimensional parameters of brailleDimensional parameters of braille shall reflect the technical correlations between the in
32、dividual parameters. For example if the smallest dot diameter and dot spacing are chosen, all other dimensions shall be proportional.4 Application of braille on signage, equipment and appliances4.1 GeneralMaterials used for braille shall attain good tactile readability, have a surface and edge that
33、will not cause harm when touched, be durable, 4 ISO 2013 All rights reservedBS ISO 17049:2013ISO 17049:2013(E) not be damaged in normal use, and not be adversely affected by the external thermal environment, moisture or liquid.Where braille and print are both used, the readability of one format shal
34、l not impair the readability of the other.Braille shall be located on a place that is safe to touch, e.g. away from a source of heat or a sharp edge.Where the information displayed in braille is revised, braille information shall be immediately corrected accordingly.4.2 Braille on signage4.2.1 Gener
35、alSignage with braille shall be located in appropriate positions for easy access.The number of cells in a single line shall be as follows:a) if there is only one column in one line, the number of cells shall not exceed 40;b) if there are multiple columns in one line, the number of cells in one colum
36、n shall not exceed 40 and the total number of cells shall not exceed 80 in a single line;c) an exclusion zone of three or more cells shall be placed between each column in a single line.4.2.2 HandrailOne application, among others, is on a handrail (see Figure 5).Braille shall be displayed parallel t
37、o the longitudinal direction of a handrail.Braille shall be displayed on the area where it can be most easily read, and which allows safe reading by touch when a hand holds the handrail. Such an area should be chosen by considering the shape, thickness, surroundings and the method by which the handr
38、ail is fixed.For a handrail on stairs, braille should be displayed at the end of the handrail, which is an extension of tactile walking surface indicators (TWSI) (see ISO 23599), if any, on the floor in front of the stairs.Handrails with braille should have extensions, preferably of at least 300 mm
39、in length on both ends of the staircase; this is to allow for safe reading of braille.

40、rence room ( second floor: the large hall)Figure 5 Example: handrails for stairsIn cases where there are handrails on both sides of a room door, the signage with braille shall be placed on the side of the handrail where the door opens (ledge side). Where it is required to indicate the direction of t
41、he door or opening, the signage with braille should be placed on both sides of the handrail, and shall include a symbol, such as a tactile shape of an arrow or the specific combination of braille patterns which indicates an arrow (see Figure 6).21Key1 Meeting room 2 ( Meeting room 2)2 Meeting room 2

Figure 6 Example: room doorway4.3 Braille for the controls of equipment and appliances4.3.1 GeneralBraille for the controls of equipment and appliances shall be placed on the same surface with t
43、he controls.Braille shall not be placed diagonally, nor in curved or upside-down arrangements.6 ISO 2013 All rights reservedBS ISO 17049:2013ISO 17049:2013(E)An exclusion zone shall be used around a braille cell or cells.NOTE Placing braille near operative buttons with a rise or similar kind of prot
44、rusions can hinder the movement of fingers in reading braille (see Figure 3).Braille labelling of independent and adjoined controls in the same line should be separated by an exclusion zone of two or more cells in order to avoid misreading. Even with limited space, an exclusion zone of one and a hal
45、f cells shall be used (see Figure 7).abcxyzabc xyzFigure 7 Exclusion zones and adjoined braille4.3.2 ButtonsBraille should not be placed on a button.Braille shall not be placed on a ring around a control button unless it can be presented in a straight horizontal line.Braille may be placed on the but
46、tons if the buttons cannot be identified by touch or there is no space for braille around a button, and if there is no possibility of unintended operation by reading braille.Where buttons are arranged horizontally, braille shall be above and adjacent to the corresponding buttons.Where buttons are ar
47、ranged vertically, braille shall be placed to the left of and adjacent to the corresponding buttons.4.3.3 DialsBraille should be placed on or around dials, and in the same orientation as the print.
