ISO/IEC Guide 71:2014Guide for addressing accessibility in standards
Andrew ArchDigital Government Strategy Department of Finance
Purpose
Help designers, manufacturers and educators gain a better understanding of the accessibility requirements of an increasing part of the population;
Increase the number of standards containing accessibility considerations, with perhaps a greater number focusing specifically on accessibility;
Integrate accessibility features into standards – and product or service design – from the outset.
Abstract
Provides guidance to standards developers on addressing accessibility requirements and recommendations in standards that focus, whether directly or indirectly, on systems (i.e. products, services and built environments) used by people.
To assist standards developers to define accessibility requirements and recommendations, it presents:
a summary of current terminology relating to accessibility
issues to consider in support of accessibility in the standards development process
a set of accessibility goals (used to identify user accessibility needs)
descriptions of (and design considerations for) human abilities and characteristics
strategies for addressing user accessibility needs and design considerations in standards

Accessibility in the standards development process
1. Define the standards project and the applicability of Guide 71
2. Ensure the standards development committee is well equipped to implement an accessible process with equitable participation
3. Develop the content of the standard
4. Issue the draft standard for public review and vote and revise the standard as needed
5. Publish the standard
Applying Guide 71
Identifies two complementary approaches to addressing accessibility
An ‘accessibility goals approach’ – identifying user accessibility needs
A ‘human abilities and characteristics approach’ - identifying design considerations
Accessibility Goals
1. Suitability for the widest range of users
2. Conformity with user expectations
3. Support for individualization
4. Approachability
5. Perceivability
6. Understandability
7. Controllability
8. Usability
9. Error tolerance
10. Equitable use
11. Compatibility with other systems
Human Abilities and Characteristics
Discusses a range of impairments and their limitations and related design considerations:
Sensory abilities and characteristics (seeing, hearing, touch, taste, smell)
Immunological system functions
Physical abilities and characteristics (body size, movement, strength and endurance, voice and speech functions)
Cognitive abilities
Strategies for addressing user accessibility needsand design considerations in standards
Developing standard-specific requirements and recommendations
Provide multiple means of information presentation and user interaction
Set parameter to accommodate the widest range of users
Minimise unnecessary complexity
Provide individualised access to a system
Eliminate unnecessary limits or constraints on user interactions
Provide compatibility with ATs
Provide alternative versions
Pros
Uses the International Classification of Functioning, Disability and Health (ICF) from the World Health Organisation (WHO) as a resource for terminology
Released identically as:
CEN/CENELEC Guide 6 (PDF)
ITU H-series Supplement 17
Includes lots of design consideration guidance
Includes a checklist for the questions related to the accessibility goals
Provides extensive additional references
Links to a survey to obtain feedback and information about experiences using the Guide
Has good accessibility in PDF
Cons
No guidance as to which approach might suit what type of standard
40 questions to consider for the accessibility goals
Could have been a higher level set of checks (11 areas)
Very complex concepts for people with no disability/accessibility background
Overlooks some key WCAG 2.0 accessibility issues such as specifying flicker rates for seizures and minimum colour ratios
Includes Key Actions such as “Ensure that all commenting and voting tools are accessible” without any guidance
Potential conflict with EC Mandate 473 (inclusion of ‘design for all’ in relevant CEN/CENELEC/ETSI European standardisation initiatives)
Guide 71 is only available in PDF
