18、rvices Page 4 EN 1970:2000 Foreword This European Standard has been prepared by Technical Committee CENTTC 293, Technical aids for disabled persons, the Secretariat of which is held by SIS. This European Standard shall be given the status of a national standard, either by publication of an identical
19、 text or by endorsement, at the latest by December 2000, and conflicting national standards shall be withdrawn at the latest by December 2000. This European Standard has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essent
20、ial requirements of EU Directive( s) . For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this standard. According to the CENKENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European S
21、tandard: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom. This standard provides one means to demonstrate that adjustable beds for disabled persons, whic
22、h are also medical devices, conform to the essential requirements outlined in general terms in Annex 1 of the EU Directive 93/42/EEC. It is not intended to provide a means to show conformity with the requirements of any other directive. There are three levels of European Standards dealing with techn
23、ical aids for disabled persons. These are as follows, with level 1 being the highest: Level 1: Level 2: Level 3: General requirements for technical aids Particular requirements for families of technical aids Specific requirements for types of technical aids. Where standards for particular aids or gr
24、oups of aids exist (level 2 or 3), the requirements of lower level standards take presedence over higher level standards. Therefore, to address all requirements for a particular aid, it is necessary to start with standards of the lowest available standard. This is a combined level 2- and 3- standard
25、 (lowest possible) for adjustable beds for disabled persons, which are also medical devices, as specified in the scope. 8 BSI 082000 COPYRIGHT European Committee for Standardization Licensed by Information Handling Services COPYRIGHT European Committee for Standardization Licensed by Information Han

27、ending on the product in question. The risk analysis should be used for determining if further or other requirements should be addressed for each specific product. Due to the dissimilarity of disabilities to be alleviated, it is not possible to specify requirements for adjustable beds for disabled p
28、ersons in such a way that any bed of this type is covered. The present standard is therefore intended to cover the major part of adjustable beds for disabled persons. Certain beds, e.g. those designed to meet special needs, might need to fulfil other or further requirements, e.g. regarding ergonomic
29、s or EMC, than specified in this standard. Beds covered by the present standard differ from beds covered by the IEC standard on electrically operated hospital beds, e. g. due the following characteristics: - beds for disabled persons are intended to be used instead of domestic beds for permanent use
30、, with the intention of alleviating or compensating for a disability or handicap and to facilitate better working conditions for attendants; - beds for disabled persons do not require the same level of strength and cleaning as hospital beds, due to the different application; - beds for disabled pers
31、ons do not require the same electrical performance as hospital beds due to the different application.

32、ge 6 EN 1970:2000 1 Scope This standard specifies essential requirements and related test methods for non-electrically and electrically operated adjustable beds, including detachable bed boards, bed lifts, side rails, grab handles and lifting poles intended to be used by disabled persons to alleviat
33、e or compensate for a disability or handicap. The standard also applies to stand up beds. The standard does not apply to lateral tilt beds. The standard does not apply to beds intended for use in the diagnosis, treatment or monitoring of patients under medical supervision (covered by EN 60601 -2-38
34、for electrically operated hospital beds). The standard does not apply to ordinary domestic beds, beds intended for children under 12 years of age, and mattresses. The requirements in this standard do not take into account extreme heavy duty use of the bed. 2 Normative references This European Standa
