4 Basic policies
The basic policies which shall be followed with respect to office equipment in order to ensure and
improve accessibility are as follows.
a) The office equipment shall be planned and developed to be usable by older persons and persons
with disabilities, by meeting the requirements in Clause 6.
b) The methods that shall meet the requirements in Clause 6 may be the function of the office
equipment itself or the software operated with connected personal computers. When the
requirements are met by application software on mobile devices, the requirements provided in
ISO/IEC 40500 shall be met.
c) The methods that shall meet the requirements in Clause 6 can be the standard form of office
equipment, or with its option.
d) An alternative method shall be accepted, if there is no other direct method meeting the requirements
in Clause 6.
e) The essential functions and performance of office equipment shall not be interfered by the attempt
to meet the requirements in Clause 6.
f) Accessibility shall be ensured and improved, within the safety of user. Extra consideration shall
be needed to ensure the safety of users with disabilities, for they sometimes have to operate office
equipment following different steps from people without disability, because of their impairments.
g) The operations that are targeted in 6.7 are as follows. For others (from 6.1 to 6.6, and from 6.8 to
6.12), all operations are targeted.
1) Required target operations
— power up /power down / power save / authenticate;
— place a document on platen glass / auto document feeder, and take out;
— select and perform a function (copy, fax, scan, and print);
— take out printed paper;
— perform user registration and management;
— perform actions for security management;
— change the settings (such as defaults) of functions (copy, fax, scan, and print).
2) Recommended target operations
When the safety of older persons and persons with disabilities can be ensured, the following
operations should be targeted.
— install hardware;
— supply paper;
— remove a paper jam;
— replace a consumable.
h) The functions targeted in Clause 6 shall be equivalent to the functions provided to people without
disabilities.
i) When the status of the conformity with Clause 6 is provided, it shall be shown including the status
of consideration each disability shown in Clause 5.

5 Classification of disabilities
5.1 Classification and characteristics of disabilities
5.1.1 General rules
Disabilities targeted in the guidelines are shown from 5.1.2 to 5.1.11.
For specific requirements which office equipment is to consider can be referred in Clause 6. Each
disability also shall include the state of disabilities due to temporary injuries and illness.
For older persons, they shall be considered to have a mild symptom that is not included in the following
targeted “disabilities”, or multiple mild symptoms, and giving consideration to each disability leads to
considerations for older persons.
The classification of disabilities is classified by referring to the classification of ISO/IEC Guide 71 and
harmonized with the classification of US Section 508 Standards and EN 301 549, premising the use of
office equipment.
5.1.2 Blindness
A disability that represents the state of being unable to use vision. A prior learning is premised because
operations and actions rely on tactile sense and hearing sense. Blind people cannot make use a mouse
but can use a personal computer with a keyboard and screen reading out software. Some users use
devices such as smartphones.
5.1.3 Low vision
A disability that represents the state of being able to use vision, but it is limited. The eyesight cannot be
corrected to the degree to bear daily life even with eyeglasses. If vision can be corrected, it is not called
low vision even if eyesight is low. Some users utilize the accessibility feature of an operating system
to use a personal computer and carry a loupe with a high magnification rate. They also use assistive
devices like magnifying printed papers including books. Some users move their eyes closer to about 3
cm from the device to operate it.
5.1.4 Colour blindness
A disability that is different from normal colour sensitiveness. Colour blindness includes total colour
blindness, which is being completely unable to distinguish any colour, and colour weakness which is
difficulty distinguishing some colours. For example, it is well known that people with colour weakness
have difficulty distinguishing red and green, but there are some other combinations of colours which
are not easily distinguished. They can distinguish better by adjusting to higher contrast, but that may
change the colour tone of the user interface, which makes to persons with low vision, who rely on
colours to see, more difficult to recognize the operational parts. Meanwhile, due to aging, it becomes
difficult for people to distinguish white and yellow, and black and dark blue.
5.1.5 Deafness
A disability that represents the state of being completely unable to use hearing. Since deaf people are
unable to hear the words they themselves say, speech impairment can be induced. In daily life, as they
cannot hear the surrounding sound, it is sometimes difficult to avoid danger promptly. They may not
recognize whether a loud sound is going on or off. So, they may not even realize a vacuum cleaner is not
plugged.
5.1.6 Hearing impairment
A disability that represents the state of being partly able to use hearing by using a hearing aid or
cochlear implant. However, in many cases, they do not hear as clearly as people without a hearing

ISO/IEC 10779:2020(E)
disability, and consonants are especially unclear. They recognize the words by predicting through the
earlier conversation, or the situation. So, if the subject of conversation suddenly changes, the persons
with hearing impairment may not keep up with conversation. The ability to hear lowers due to aging,
and it becomes difficult for old persons to recognize especially the higher tones.
5.1.7 Speech impairment
A disability that represents the state of being unable to speak or being able to speak partially. There are
various cases, including speech impairment induced from congenital hearing impediment, or removing
larynx at cancer surgery. When a person is completely unable to speak, writing messages is the main
mean to communicate.
5.1.8 Impairment that limits upper limb strength and action
A disability where it is difficult to perform operations which need strength of hands and fingers, fine
motor control or both hands, because of low muscle force, low control capability, prosthetic hand
and finger, inability to use one hand, difficulty in simultaneous movement or involuntary movement
(tremor).
The difficulties are not limited to the operations that need strength, but also the operation of touch
panels or mouse, which need only low strength but require fine finger movements.
Some people may have no thermal nociception due to loss of sensation. Aging lowers muscle strength
and control capability.
5.1.9 Impairment that limits reach ranges
A disability that limits accessible ranges, which includes persons who use a cane or a wheelchair,
and impairment of upper limb and persons with low height. A wheelchair user without upper limb
problem normally uses a manual wheelchair, and wheelchair user who has upper limb problem uses an
electric wheelchair. In both cases, as the users have to stretch a hand out from the sitting position, the
accessible ranges of the high area, the low area, and th
...
