This British Standard specifies requirements for the design, manufacture, installation, commissioning, testing, maintenance and dismantling of new permanently installed electrically powered homelifts with the following characteristics: travelling vertically between two predefined levels along a guided path where the inclination to the vertical does not exceed 15°; supported or sustained by wire rope or chains, hydraulic cylinder (direct or indirect), screw and nut; penetrating a single floor; affixed to a building structure; where the carrier is partially enclosed; having a speed not greater than 0.15m/s. This British Standard is applicable to homelifts that are installed in private dwellings 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 be used as guidance for the refurbishment and re-installation of existing homelifts.
