This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by June 2009, and conflicting national standards shall be withdrawn at the latest by December 2009. This document supersedes EN 15095:2007. This document includes Amendment 1, approved by CEN on 2008-11-09. The start and finish of text introduced or altered by amendment is indicated in the text by tags !“. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive(s). !For relationship with EU Directive(s), see informative Annexes ZA and ZB, which are integral parts of this document.“ According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and the United Kingdom. -,-,- EN 15095:2007+A1:2008 (E) 5 Introduction This standard is a type C standard as stated in EN ISO 12100. The machinery concerned and the extent to which hazards, hazardous situations and hazardous events are covered are indicated in the scope of this standard. For machines designed and built according to the specifications of this Type C Standard the following applies: “When provisions of this type C standard are different from those which are stated in type A or B standards, the provisions of this type C standard take precedence over the provisions of the other standards for machines that have been designed and built according to the provisions of this type C standard.“ When this standard was prepared it was assumed that: only trained staff would operate, repair or maintain the machine; components without special requirements are 1) sized in accordance with good engineering practice and methods of calculation including all types of failure; 2) correctly constructed mechanically and electrically; 3) made of materials of adequate loading capacity and of suitable quality; 4) made of materials that are fit for that purpose. components are kept in a good repair and operating condition so that the required characteristics can be maintained in spite of wear and tear; sizing of load bearing parts ensures safe operation of the machine in a loading range from 0 % to 100 % of the nominal capacity and during testing conditions if applicable; details of particular conditions of use and the installation site are agreed between user and manufacturer; working area is adequately illuminated; installation site permits safe operation of the machine. -,-,- EN 15095:2007+A1:2008 (E) 6 1 Scope 1.1 This European Standard deals with the safety requirements for the following types of power-operated storage equipment: storage carousels; storage lifts; mobile shelving, pallet racking and cantilever racking with the objective of eliminating or minimising the hazards described in Clause 4. These hazards can arise during installation, starting up, operation, maintenance, testing and dismantling of the equipment. 1.2 It is essential that the safety requirements and/or measures taken in this standard be applied to storage equipment which operates indoors. Under difficult conditions, it is essential that additional hazard analysis and safety measures be taken into account, e. g. outdoor conditions, freezer applications, high temperatures, corrosive environment, strong magnetic fields, risk of explosive atmosphere, radioactive conditions, storage goods which due to their nature could generate hazardous situations (e. g. molten metal, acids/alkalis, fragile goods or explosives), effects of earthquakes and also contact with food. 1.3 Examples of power-operated storage equipment to which this standard applies are shown in Annex A. 1.4 With regard to buildings and parts of buildings, this standard applies only insofar that an assessment regarding hazards and risks in connection with interfaces to the storage equipment is carried out. 1.5 Storage equipment whose only power source is directly used human labour or gravity are excluded from the scope of application of this standard. 1.6 Power-operated storage equipment or parts of them do not fall under the regulations for passenger lifts. They are intended to handle and store goods. They are not intended to transport passengers under normal use (except for maintenance) and therefore not considered to be lifts (elevators). 1.7 This standard does not take hazards into account, which arise from noisy environments or environments subject to electromagnetic interference outside the range quoted in EN 61000-6-2. 2 Normative references The following referenced documents are indispensable for the application of this document.

The in-built lift unit carries the load carriers (e.g. storage containers) from an access opening to storage locations in a racking tower, or from a storage location to an access opening. Storage lifts can have one or more access openings on one or more levels (see Figure A.3) 3.3 mobile shelving mobile shelving comprises a series of hand loaded adjustable load carrying surfaces (shelves) supported by upright frames all of which is in turn fixed to a movable base unit. This base unit is supported on wheels mounted in the base unit which run on rails mounted in or on the floor. The system is designed to be loaded by hand with multiple loads all of which are substantially less than the total carrying capacity of the shelf. The system is not designed to be loaded or unloaded by mechanical equipment (see Figure A.4) 3.4 mobile racking mobile racking comprises a skeleton framework of fixed or adjustable design supporting unit loads generally without the use of shelves. This skeleton framework is in turn fixed to movable base units supported on wheels mounted in the base unit, which run on rails mounted in the floor. The system is designed for the storage of unit loads where loading or unloading is generally by mechanical means (see Figure A.5) 3.5 cable barriers current carrying access barrier 3.6 access opening opening in cladding or covers for the purposes of loading and unloading 3.7 compartment load intended permissible uniformly distributed load of a horizontal load carrying surface between two upright frames 3.8 bay load sum or compartment loads between two upright frames (including base supported compartment load) 3.9 accidental stop stopping of racking equipm
