CEN/TC 122/WG 2 - Ergonomic design principles

This document provides ergonomics data for standard developers to use in applying ISO/IEC Guide 71:2014 to address accessibility in standards. These data can also be used by ergonomists and designers to support the development of more accessible products, systems, services, environments, and facilities.
The ergonomics data include quantitative data and knowledge about basic human characteristics and capabilities as well as context-specific and task-specific data, all being based on ergonomics research. The data focused on the effects of ageing and/or consequences of various types of human sensory, physical, and cognitive disabilities. It does not contain general ergonomics data that have no direct relation to ageing or disabilities.
The data presented in this document are not exhaustive due to no available data for some aspects of human characteristics and capabilities with regard to ageing and disabilities.

This document is intended to be used within organizations that embrace and intend to implement the principles of human centredness outlined in ISO 27500.
This document is intended to provide requirements and recommendations on the human factors and ergonomics approach to achieving a successful and sustainable human-centred organization. It outlines managers' responsibilities ranging from organizational strategy to development of procedures and processes enabling human centredness, and the implementation of those procedures and processes.
This document provides requirements and recommendations for managers and the actions to be taken in order for an organization to achieve human centredness.
This document can be used:
a)    by managers to understand and improve human-centred aspects of their activities;
b)    by managers to identify how their staff can improve human-centred aspects of their activities;
c)    to provide a basis for training managers how to be human-centred;
d)    to provide a basis for organizations to evaluate the performance of managers.
It is not a management systems standard. Nor is it intended to prevent the development of standards that are more specific or more demanding.

ISO 10075-1:2017 defines terms in the field of mental workload, covering mental stress and mental strain, and short- and long-term, positive and negative consequences of mental strain. It also specifies the relations between these concepts involved.
In this document, mental workload is regarded as an umbrella or generic term, referring to all the concepts and constructs mentioned in the document and does not have a specified or standardized meaning of its own within the document. This is consistent with the use of the term in ergonomics and its applications, where it can refer to mental stress, mental strain and their effects, i.e. both to the causes and the effects. In this document, the term mental workload will thus not be treated as a technical term but only as a reference to the domain of mental workload.
NOTE       Annex A gives additional explanations of terms and concepts.
ISO 10075-1:2017 applies to the design of working conditions with respect to mental workload and is intended to promote a common usage of terminology between experts and practitioners in the field of ergonomics as well as in general.
ISO 10075-1:2017 does not address methods of measurement and principles of task design, which are dealt with in ISO 10075‑2 and ISO 10075‑3.

ISO 27500:2016 is intended for executive board members and policy makers of all types of organizations (whether large or small) in the private, public and non-profit sectors.
It describes the values and beliefs that make an organization human-centred, the significant business benefits that can be achieved, and explains the risks for the organization of not being human-centred. It provides recommendations for the policies that executive board members need to implement to achieve this. It sets out high-level human-centred principles for executive board members to endorse in order to optimize performance, minimize risks to organizations and individuals, maximize well-being in their organization, and enhance their relationships with the customers. The importance of organizational policy to address human-centredness is emphasized.
ISO 27500:2016 is not a management system standard. It is not intended or appropriate for certification purposes or regulatory or contractual use.
ISO 27500:2016 is not intended to prevent the development of national standards that are more specific or demanding.

ISO 6385:2016 establishes the fundamental principles of ergonomics as basic guidelines for the design of work systems and defines relevant basic terms. It describes an integrated approach to the design of work systems, where ergonomists will cooperate with others involved in the design, with attention to the human, the social and the technical requirements in a balanced manner during the design process.
Users of this International Standard will include executives, managers, workers (and their representatives, when appropriate) and professionals, such as ergonomists, project managers and designers who are involved in the design or redesign of work systems. Those who use this International Standard can find a general knowledge of ergonomics (human factors), engineering, design, quality and project management helpful.
The term "work system" in this International Standard is used to indicate a large variety of working situations, including permanent and flexible work places. The intention of this International Standard is to assist in the improvement, (re)design or change of work systems. Work systems involve combinations of workers and equipment, within a given space and environment, and the interactions between these components within a work organization. Work systems vary in complexity and characteristics, for example, the use of temporary work systems. Some examples of work systems in different areas are the following:
-      production, e.g. machine operator and machine, worker and assembly line;
-      transportation, e.g. driver and car or lorry, personnel in an airport;
-      support, e.g. maintenance technician with work equipment;
-      commercial, e.g. office worker with workstation, mobile worker with a tablet computer, cook in a restaurant kitchen;
-      other areas like health care, teaching and training.
The observance of ergonomic principles applies to all phases throughout the life cycle of the work system from conception through development, realization and implementation, utilization, maintenance and support to decommissioning.
The systems approach in this International Standard gives guidance to the users of this International Standard in existing and new situations.
The definitions and ergonomic principles specified in this International Standard apply to the design of optimal working conditions with regard to human well-being, safety and health, including the development of existing skills and the acquisition of new ones, while taking into account technological and economic effectiveness and efficiency.
The principles in this International Standard are applicable to many other human activities, e.g. in the design of products for domestic and leisure activities. A more general description of the principles in this International Standard can be found in ISO 26800.

This European Standard describes a procedure for analysing human activity in relation to specifying and refining the human component in the design or redesign of machinery and work systems.
NOTE 1   The ergonomics methodology described in this European Standard could also be applied to the design or redesign of products and non-work systems.
This European Standard is intended to assist project leaders in implementing human and physical resources, methods and schedules as well as in preparing the documents necessary to meeting related requirements.
The ergonomics methodology described can be applied to all different stages in design projects from the earliest concept to the final “prototype” or “mock-up”, whatever the industrial field or sector.
The objective of this European Standard is to achieve a solution that takes into account as many situations as possible which all users - including operators, maintenance staff and installers, may encounter. This will ultimately allow improved usability of the machinery and more robust technical solutions, combined with significantly greater system resilience, user autonomy and accessibility.
NOTE 2   Examples of the application of the methodology described in this European Standard are provided in Annex A.

This document describes the "Feedback Method", a method designed specifically to collect the contribution of machinery end-users by reconstructing and understanding how work is actually performed (i.e. the real work). This method can help to improve technical standards, as well as the design, manufacturing, and use of machinery.
By collecting the experiences of skilled users, this method can be used to reconstruct their actual work activities under different operating conditions and with any kind of machine. This helps to identify all the critical aspects having an impact on health and safety, or associated with ergonomic principles. Moreover, it makes it possible to identify some basic elements for defining the standards for machines and for their revision and improvement. It can also improve production efficiency and identify any need for additional study and research.
The method is designed to minimize the influence of the subjectivity of the facilitators and researchers in reconstructing and describing the reality of work, and to maximize the "objective" contribution of the skilled users of the machine.
The method combines a high level of reproducibility, sensitivity, and user-friendliness with low demands in term of resources, which makes it attractive to micro, small and medium-sized enterprises.
This Technical Report is addressed to standards writers, designers and manufacturers, employers-buyers, end users, craftsmen and workers, market surveillance and authorities.
