Medical electrical equipment - Particular requirements for the basic safety and essential performance of medical beds for children
This Standard applies to the BASIC SAFETY and ESSENTIAL PERFORMANCE of MEDICAL BEDS, hereafter referred to as MEDICAL BEDS as defined in 201.3.218, intended for CHILDREN as defined in 201.3.207, and ADULTS with atypical anatomy (ADULTS ranging outside the definition for ADULTS in 201.3.201).
This standard applies to medical beds with nonadjustable and electrical / mechanical adjustable functions.
This Standard applies to MEDICAL BEDS with an internal length of up to 180 cm suitable to a body length of 155 cm.
NOTE 1 The limitation of 180 cm is in order to minimize the foreseeable misuse, of a parent sharing the bed with the child or that the bed will be used by an ADULT.
If a manufacturer wishes to make a bed that can be used by both a child and an ADULT, e.g. length of 180 cm or more, then it will fulfil both EN 60601-2-52 and this particular standard.
This Standard does not apply to MEDICAL BEDS intended for ADULTS as defined in 201.3.201 (covered by EN 60601-2-52).
This Standard does not apply to :
- incubators covered by EN 60601-2-19 ;
- beds for children, covered by EN 716-1 and EN 716-2 ;
- cribs and cradles covered by EN 1130 (all parts) ;
- bunk beds and high beds, covered by EN 747-1 and 747-2.
If a clause or subclause is specifically intended to be applicable to a MEDICAL BED only, or to ME SYSTEMS only, the title and content of that clause or subclause will say so. If that is not the case, the clause or subclause applies both to MEDICAL BEDS and to ME SYSTEMS, as relevant.
HAZARDS inherent in the intended physiological function of MEDICAL BED or ME SYSTEMS within the scope of this standard are not covered by specific requirements in this standard except in 7.2.13 and 8.4.1 of EN 60601-1:2006.
NOTE 2 See also 4.2 of EN 60601-1:2006.
NOTE 3 Body length is measured from crown to sole.
1.2 Object
The object of this particular standard is to establish particular BASIC SAFETY and ESSENTIAL PERFORMANCE requirements and test methods for MEDICAL BEDS as defined in 201.3.218 intended for CHILDREN as defined in 201.3.207.

Diese Norm gilt für die BASISSICHERHEIT einschließlich der WESENTLICHEN LEISTUNGSMERKMALE von MEDIZINISCH GENUTZTEN BETTEN, nachfolgend als MEDIZINISCH GENUTZTE BETTEN bezeichnet, wie in 201.3.218 definiert, die für KINDER entsprechend der Definition in 201.3.207 und für ERWACHSENE mit atypischer Anatomie (ERWACHSENE, die nicht unter die Definition für ERWACHSENE in 201.3.201 fallen) vorgesehen sind.
Diese Norm gilt für medizinische Betten mit nicht einstellbaren und mit einstellbaren elektrischen/ mechanischen Funktionen.
Diese Norm gilt für MEDIZINISCH GENUTZTE BETTEN mit einer Innenlänge von bis zu 180 cm, die für eine Körperlänge von 155 cm geeignet sind.
ANMERKUNG 1 Die Begrenzung auf 180 cm soll den vernünftigerweise vorhersehbaren Missbrauch minimieren, dass sich ein Elternteil das Bett mit dem KIND teilt oder dass das Bett von einem ERWACHSENEN genutzt wird.
Wenn ein HERSTELLER ein Bett herstellen möchte, dass sowohl von einem KIND als auch von einem ERWACHSENEN genutzt werden kann, z. B. mit einer Länge von 180 cm oder mehr, dann wird es EN 60601-2-52 sowie diese Besonderen Festlegungen erfüllen.
Diese Norm gilt nicht für MEDIZINISCH GENUTZTE BETTEN, die für ERWACHSENE entsprechend der Definition in 201.3.201 vorgesehen sind (diese sind von EN 60601-2-52 erfasst).
Diese Norm gilt nicht für:
- Inkubatoren, die in EN 60601-2-19 behandelt werden;
- KINDERBETTEN, die in EN 716-1 und EN 716-2 behandelt werden;
- KRIPPEN und Wiegen, die in EN 1130 (alle Teile) behandelt werden;
- Etagenbetten und Hochbetten, die in EN 747-1 und EN 747-2 behandelt werden.
Ist ein Abschnitt oder Unterabschnitt speziell nur für die Anwendung auf ein MEDIZINISCH GENUTZTES BETT oder nur auf ME-SYSTEME vorgesehen, ist dies aus Überschrift und Inhalt des Abschnittes oder Unterabschnittes ersichtlich. Ist das nicht der Fall, trifft der Abschnitt oder Unterabschnitt, wo anwendbar, sowohl auf das MEDIZINISCH GENUTZTE BETT als auch auf das das ME-SYSTEM zu.
GEFÄHRDUNGEN, die sich aus der vorgesehenen physiologischen Wirkungsweise von MEDIZINISCH GENUTZTEN BETTEN oder ME-SYSTEMEN im Anwendungsbereich dieser Norm ergeben, sind nicht durch besondere Anforderungen in dieser Norm erfasst, ausgenommen in EN 60601-1:2006, 7.2.13 und 8.4.1.
ANMERKUNG 2 Siehe auch von EN 60601-1:2006, 4.2.

EN 50637:2017 (E) 6 Introduction EN 60601-2-52 applies to the BASIC SAFETY and ESSENTIAL PERFORMANCE of MEDICAL BEDS for ADULTS, hence not covering requirement for beds for CHILDREN and ADULTS with atypical anatomy. This particular standard is based on the Mandate M/467 Medical beds issued by the European Commision with the following background information: It appears, from a first analysis undertaken by Competent Authorities, that the current set of standards is not adapted to the needs of CHILDREN or ADULTS with an atypical anatomy. EN 60601-2-52 does not foresee a maximum distance for the bars that is small enough to prevent accidents. According to the Competent Authorities’ representatives, a part of the safety problem is due to the fact that medical beds for ADULTS are not appropriately labelled as being designed only for ADULTS with a normal anatomy. Users are therefore not always aware of the risk of medical beds for young PATIENTS or for ADULTS with an atypical anatomy. Hospital administrations do not always see a need to buy medical beds which are appropriate for CHILDREN or for ADULTS with an atypical anatomy. Therefore, clear labelling of the targeted PATIENT groups for medical beds complying with EN 60601-2-52 could reduce the risk of inappropriate use of this kind of medical beds for CHILDREN or for ADULTS with an atypical anatomy. Labeling is taken care of by Amendment 1 of EN 60601-2-52. Competent Authorities’ representatives also stated that there is a need for the development of requirements for MEDICAL BEDS and COTS for CHILDREN and ADULTS with an atypical anatomy. In order to prevent EN 60601-2-52 from being extraordinary complex to use, CLC/TC 62 decided to develop this particular standard rather than further amending EN 60601-2-52 in relation to use for CHILDREN and ADULTS with an atypical anatomy. This standard is based on input from the following standards and reports: • EN 60601-2-52, Medical electrical equipment — Part 2-52: Particular requirements for basic safety and essential performance of medical beds (IEC 60601-2-52)1); • EN 716-1, Furniture — Children's cots and folding cots for domestic use — Part 1: Safety requirements; • EN 716-2, Furniture — Children's cots and folding cots for domestic use — Part 2: Test methods; • EN 1130-2, Furniture — Cribs and cradles for domestic use — Part 2: Test methods; • EN 747-1, Furniture — Bunk beds and high beds — Part 1: Safety, strength and durability requirements; • EN 747-2, Furniture — Bunk beds and high beds — Part 2: Test methods; • CEN/TR 13387 (all parts), Child use and care articles — General safety guidelines; • DIN 32623, Hospital children's cots made from metal and plastic — Safety requirements and testing; • Nordic Requirements specification for Adjustable beds for disabled children.

EN 50637:2017 (E) 7 201.1 Scope, object and related standards Clause 1 of EN 60601-1:2006, Medical electrical equipment — Part 1: General requirements for basic safety and essential performance, applies, except as follows: 201.1.1 * Scope Replacement: This Standard applies to the BASIC SAFETY and ESSENTIAL PERFORMANCE of MEDICAL BEDS, hereafter referred to as MEDICAL BEDS as defined in 201.3.218, intended for CHILDREN as defined in 201.3.207, and ADULTS with atypical anatomy (ADULTS ranging outside the definition for ADULTS in 201.3.201). This standard applies to medical beds with nonadjustable and electrical / mechanical adjustable functions. This Standard applies to MEDICAL BEDS with an internal length of up to 180 cm suitable to a body length of 155 cm. NOTE 1 The limitation of 180 cm is in order to minimize the foreseeable misuse, of a parent sharing the bed with the child or that the bed will be used by an ADULT. If a manufacturer wishes to make a bed that can be used by both a child and an ADULT, e.g. length of 180 cm or more, then it will fulfil both EN 60601-2-52 and this particular standard. This Standard does not apply to MEDICAL BEDS intended for ADULTS as defined in 201.3.201 (covered by EN 60601-2-52).
This Standard does not apply to : • incubators covered by EN 60601-2-19 ; • beds for children, covered by EN 716-1 and EN 716-2 ; • cribs and cradles covered by EN 1130 (all parts) ; • bunk beds and high beds, covered by EN 747-1 and 747-2. If a clause or subclause is specifically intended to be applicable to a MEDICAL BED only, or to ME SYSTEMS only, the title and content of that clause or subclause will say so. If that is not the case, the clause or subclause applies both to MEDICAL BEDS and to ME SYSTEMS, as relevant. HAZARDS inherent in the intended physiological function of MEDICAL BED or ME SYSTEMS within the scope of this standard are not covered by specific requirements in this standard except in 7.2.13 and 8.4.1 of EN 60601-1:2006. NOTE 2 See also 4.2 of EN 60601-1:2006. NOTE 3 Body length is measured from crown to sole. 201.1.2 Object Replacement: The object of this particular standard is to establish particular BASIC SAFETY and ESSENTIAL PERFORMANCE requirements and test methods for MEDICAL BEDS as defined in 201.3.218 intended for CHILDREN as defined in 201.3.207. 201.1.3 Collateral standards Addition: This particular standard refers to those applicable collateral standards that are listed in Clause 2 of EN 60601-1:2006 standard and its accociated amendments and corrigenda and Clause 2 of this particular standard.
