Introduction
The population of Europe is ageing and the prevalence of disability, including disability associated with
the ageing process, is increasing. Older people and people with disabilities at present are estimated to
number some 80 million people – a large and growing proportion of the European Union population. The
changing demography presents both opportunities and challenges for the Union. The economic, social
and cultural potential of older people and people with disabilities is underexploited at present. However,
there is a growing recognition that society needs to exploit this potential for the economic and social
benefit of society generally.
This is one of the reasons that led to this document on vertical lifting platforms for people with impaired
mobility being one means to provide accessibility to buildings.
This document is a type C standard as stated in EN ISO 12100:2010.
This document is of relevance, in particular, for the following stakeholder groups representing the market
players with regard to machinery safety:
— machine manufacturers (small, medium and large enterprises);
— health and safety bodies (regulators, accident prevention organizations, market surveillance etc.).
Others can be affected by the level of machinery safety achieved with the means of the document by the
above-mentioned stakeholder groups:
— machine users/employers (small, medium and large enterprises);
— machine users/employees (e.g. trade unions, organizations for people with special needs);
— service providers, e.g. for maintenance (small, medium and large enterprises);
— consumers (in case of machinery intended for use by consumers).
The above-mentioned stakeholder groups have been given the possibility to participate at the drafting
process of this document.
The machinery concerned and the extent to which hazards, hazardous situations or hazardous events are
covered are indicated in the Scope of this document.
When requirements of this type-C standard are different from those which are stated in type-A or type-B
standards, the requirements of this type-C standard take precedence over the requirements of the other
standards for machines that have been designed and built according to the requirements of this type-C
standard.
Assumptions
With the aim of clarifying the intentions of the standard and avoiding doubts when reading it, the
following assumptions were made when producing it:
a) components without specific requirements are:
1) designed in accordance with the usual engineering practice and calculation codes, including all
failure modes;
2) of sound mechanical and electrical construction;
b) general electrical hazards are dealt with according to B level electrical safety standards;
c) components are kept in good repair and working order, in accordance with the maintenance manual,
so that the required characteristics remain despite wear;
d) by design of the load bearing elements, a safe operation of the machine is ensured throughout the
entire maximum working load range;
e) a mechanical device built according to good practice and the requirements of the standard, will not
deteriorate to a point of creating a hazard without the possibility of detection;
f) the ambient temperature is between 0 °C and +40 °C, at the place of use of the machinery;
g) Negotiation occurs between the manufacturer (the person applying the CE mark) and the user
concerning the specificity of the use and places of use of the stairlift:
1) suitability for user (see Annex D);
2) the place of installation allows a safe use for the machine (see Annex C);
3) any additional fire protection requirements.
