The principal changes are to update thetext to meet the essential health and safety requirements of Machinery Directive2006/42/EC 1 as enacted as the Supply of Machinery (S
20、afety) Regulations2008 2.Presentational conventionsThe provisions of this standard are presented in roman (i.e. upright) type.

23、ry Directive 2006/42/EC 1, and additionallyspecifies minimum requirements for the provision of powered homelifts inprivate dwellings.NOTE As a general rule, the Lifting Equipment and Lifting Operations Regulations1998 3 do not apply to homelifts in private dwellings. However, in somecircumstances wh
24、ere a carer is employed in assisting the user to use the homelift,the regulations might apply.It is assumed that the powered homelift operates in an ambient temperature inthe range 5 C to 40 C. For temperatures outside this range, additionalmeasures might be necessary.This British Standard does not
25、specify requirements for: severe conditions (e.g. extreme environments, strong magnetic fields); lightning protection; potentially explosive atmospheres; the handling of materials, the nature of which could lead to dangeroussituations; homelifts of which the primary function is the transportation of
26、 goods; homelifts prone to vandalism; earthquakes or flooding; fire-fighting and evacuation; noise and vibrations; the design of concrete, hardcore, timber or other foundation or buildingarrangement; the design of anchorage bolts to the supporting structure; type A, B or C wheelchairs as defined in
27、BS EN 12183 and/or BS EN 12184; balancing weights or counterweights.This revision of BS 5900 deals with all significant hazards relevant to homelifts,when they are used as intended and under the conditions foreseen by themanufacturer. A list of significant hazards is given in Annex A.In order to det
28、ermine the specific characteristics of the homelift, at least thefollowing issues need to be discussed between the supplier and the specifier: environmental conditions; civil engineering considerations; other aspects related to the place of installation, including safe use of thehomelift; the use an
29、d places of use of the machinery; fire protection requirements; suitability for the user.Annex B gives information on issues which specifiers are expected to discusswith the supplier in order to select and specify a suitable homelift.BRITISH STANDARD BS 5900:2012 The British Standards Institution 20
30、12 1It is assumed that a homelift conforming to this standard is for the use ofpersons capable of using it safely and unaided, either after having been fullyinstructed in its use, or having observed clear and simple instructionspermanently displayed on the equipment. Persons not capable of safe unai
31、deduse of the homelift may be transported under the care of a fully instructedattendant for whom additional control facilities can be provided if required.Recommendations for specially adapted control devices are given in Annex C.1 ScopeThis British Standard specifies requirements for the design, ma
32、nufacture,installation, commissioning, testing, maintenance and dismantling of newpermanently installed electrically powered homelifts with the followingcharacteristics:a) travelling vertically between two predefined levels along a guided pathwhere the inclination to the vertical does not exceed 15;
33、b) supported or sustained by wire rope or chains, hydraulic cylinder (direct orindirect), screw and nut;c) penetrating a single floor;d) affixed to a building structure;e) where the carrier is partially enclosed;f) having a speed not greater than 0.15 m/s.This British Standard is applicable to homel
34、ifts that are installed in privatedwellings and are intended for the transport of persons with impaired mobility,standing or seated, with or without a wheelchair.NOTE Although this British Standard is applicable to new homelifts, it can also beused as guidance for the refurbishment and re-installati
