This standard applies to all types of S/R machines, restricted to the rails on which they travel within and outside the aisles, which embody lifting means and may embody lateral handling facilities, for the storage and retrieval of unit loads and/or long goods such as bar materials and/or for order picking or similar duties. Also included is the transfer equipment used to change between aisles. Control of machines may range from manual to fully automatic. This standard does not apply to free ranging industrial trucks or robots. References in this standard to racking, buildings and systems only apply where it is necessary to assess the hazards and risks at their interfaces with S/R machines. This standard deals with all significant hazards relevant to rail dependent storage and retrieval equipment, when they are used as intended under the conditions foreseen by the manufacturer (see Clause 4). This standard applies to machines and equipment that are manufactured after the date of issue of this standard. Illustrations of examples of machines and transfer equipment to which this standard applies are shown in Annex A. Safety requirements and/or measures in this standard apply to equipment used under indoor conditions. However, additional risk assessments and safety measures need to be considered for uses in severe conditions, e.g. freezer applications, high temperatures, loads, the nature of which could lead to a dangerous situation (e.g. especially brittle loads, explosives), earthquake effects and also contact with foodstuff. Hazards during decommissioning are not covered. This European Standard deals as well with the technical requirements for electromagnetic compatibility (EMC). Noise emitted by these machines is not considered as significant but as a relevant hazard. This means that the manufacturer of the machine is obliged to carry out noise reduction and indicate the noise level.
