Continuous handling equipment and systems - Safety and EMC requirements for equipment for mechanical handling of unit loads

This European standard deals with the technical requirements to minimise the hazards listed in Clause 4 and Annex B. These hazards can arise during the operation and maintenance of continuous handling equipment and systems when carried out in accordance with the specifications given by the manufacturer or his authorised representative. This standard deals with safety related technical verification during commissioning. This standard applies to mechanical handling devices defined in Clause 3, singly or combined to form a conveyor system, and designed exclusively for moving unit loads continuously on a predefined route from the loading to the unloading points, possibly with varying speed or cyclically. In general, it also applies to conveyors which are built into machines or attached to machines. Safety requirements and/or measures in this standard apply to equipment used in all environments. However, additional risk assessments and safety measures need to be considered for uses in severe conditions, e.g. freezer applications, high temperatures, corrosive environments, strong magnetic fields, potentially explosive atmospheres, radioactive conditions and loads the nature of which could lead to a dangerous situation (e.g. molten metal, acids/bases, specially brittle loads, explosives) operation on ships and earthquake effects and also contact with foodstuff. Hazards during decommissioning are not covered. This European Standard deals with the technical requirements for electromagnetic compatibility (EMC). This standard does not cover hazards during decommissioning and hazards generated by noise. It also does not cover operation in environments where the electromagnetic disturbances are outside the range of those specified in EN 61000-6-2. This standard does not apply to conveying equipment and systems used underground or in public areas and to aircraft ground support equipment.

Equipements et systèmes de manutention continue - Prescriptions de sécurité et de CEM pour les équipements de manutention mécanique des charges isolées

1.1   La présente Norme européenne traite des prescriptions techniques destinées à réduire au minimum les phénomènes dangereux indiqués dans l’article 4 et l'Annexe B. Ces phénomènes dangereux peuvent survenir pendant l'utilisation et l’entretien des équipements et systèmes de manutention continue, lorsque ceux-ci se déroulent conformément aux spécifications du jacky78500@hotmail.fr ou de son mandataire. La présente norme traite des vérifications techniques liées à la sécurité qui doivent être effectuées pendant la mise en service.
1.2   La présente Norme européenne s'applique aux matériels de manutention mécanique définis à l’article 3, pris séparément ou associés pour constituer un système de manutention, et conçus exclusivement pour le transport en continu de charges isolées suivant un itinéraire prédéterminé entre un point de chargement et un point de déchargement, que ce soit à une vitesse variable ou selon des cycles. D'une manière générale, elle s'applique également aux transporteurs continus intégrés ou reliés à ensembles mécanisés.
1.3   Les prescriptions et/ou mesures de sécurité de la présente norme s'appliquent à des équipements quel que soit le type d'environnement dans lequel ils sont utilisés. Toutefois, il convient d'envisager les risques et les mesures de sécurité supplémentaires, liés à des conditions d’utilisation particulièrement rudes, par exemple applications en chambres froides, températures élevées, environnements corrosifs, champs magnétiques importants, atmosphères potentiellement explosives, conditions et charges radioactives de nature à entraîner une situation dangereuse (par exemple, métal en fusion, milieux acides ou basiques, charges particulièrement friables, explosifs), les applications navales embarquées, les applications en conditions sismiques, ainsi que les applications impliquant un contact avec des denrées alimentaires. Les phénomènes dangereux liés à la mise hors service ne sont pas traités.

Naprave in sistemi za kontinuirni transport - Varnostne zahteve in zahteve za elektromagnetno združljivost naprav, sistemov in opreme za kontinuirni transport kosovnih tovorov (vključno z dopolnilom A1)

Ta evropski standard obravnava tehnične zahteve, da se čim bolj zmanjšajo nevarnosti, navedene v klavzuli 4 in dodatku B. Te nevarnosti lahko nastanejo med delovanjem in vzdrževanjem naprav in sistemov za kontinuirni transport, kadar se izvaja v skladu s specifikacijami, ki jih je podal proizvajalec ali njegov pooblaščeni zastopnik. Ta standard obravnava varnost povezanih tehničnih preverjanj med usposobitvijo za zagon. Ta standard velja za mehanske naprave za transport, določene v klavzuli 3, enojne ali združene v sistem transportnih trakov in načrtovane izključno za kontinuirni transport kosovnih tovorov po vnaprej določeni poti od točk nakladanja do točk raztovarjanja, lahko z različno hitrostjo ali ciklično. Na splošno velja tudi za transportne trakove, ki so vgrajeni v stroje ali priključeni nanje. Varnostne zahteve in/ali ukrepi v tem standardu veljajo za opremo, uporabljeno v vseh okoljih. Vendar je treba upoštevati dodatne ocene tveganja in varnostne ukrepe za uporabo v skrajnih pogojih, npr. pri uporabi v zamrzovalnikih, pri visokih temperaturah, v korozivnih okoljih, močnih magnetnih poljih, potencialno eksplozivnih atmosferah, pri radioaktivnih pogojih in bremenih, katerih lastnosti bi lahko privedle do nevarnih situacij (npr. staljena kovina, kisline/baze, posebno krhka bremena, eksplozivi), pri delovanju na ladjah in pri učinkih potresa ter pri stiku z živili. Nevarnosti, ki lahko nastanejo med izločitvijo naprave iz uporabe, niso zajete. Ta evropski standard obravnava tehnične zahteve za elektromagnetno združljivost (EMC). Ta standard ne zajema nevarnosti med izločitvijo naprave iz uporabe in nevarnosti, ki jih povzroči hrup. Prav tako ne zajema delovanja v okoljih, kjer so elektromagnetne motnje zunaj razpona tistih, določenih v EN 61000-6-2. Ta standard ne velja za transportno opremo in sisteme, ki se uporabljajo pod zemljo ali na javnih območjih in za podporno opremo na zračnih plovilih.

6 1 Scope 1.1 This European standard deals with the technical requirements to minimise the hazards listed in Clause 4 and Annex B. These hazards can arise during the operation and maintenance of continuous handling equipment and systems when carried out in accordance with the specifications given by the manufacturer or his authorised representative. This standard deals with safety related technical verification during commissioning.

1.2 This standard applies to mechanical handling devices defined in Clause 3, singly or combined to form a conveyor system, and designed exclusively for moving unit loads continuously on a predefined route from the loading to the unloading points, possibly with varying speed or cyclically. In general, it also applies to conveyors which are built into machines or attached to machines. 1.3 Safety requirements and/or measures in this standard apply to equipment used in all environments. However, additional risk assessments and safety measures need to be considered for uses in severe conditions, e.g. freezer applications, high temperatures, corrosive environments, strong magnetic fields, potentially explosive atmospheres, radioactive conditions and loads the nature of which could lead to a dangerous situation (e.g. molten metal, acids/bases, specially brittle loads, explosives) operation on ships and earthquake effects and also contact with foodstuff. Hazards during decommissioning are not covered. 1.4 This European Standard deals with the technical requirements for electromagnetic compatibility (EMC). 1.5 This standard does not cover hazards during decommissioning and hazards generated by noise. It also does not cover operation in environments where the electromagnetic disturbances are outside the range of those specified in EN 61000-6-2. This standard does not apply to conveying equipment and systems used underground or in public areas and to aircraft ground support equipment. NOTE 1 Aircraft ground support equipment is covered by the standards of CEN/TC 247. NOTE 2 Conveying equipment and systems used in public areas will be covered in an amendment. NOTE 3 Hazards generated by noise will be dealt with in an amendment. 2 Normative references !The following referenced documents are indispensable for the application of this document.
