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

    Oprindelse:
    CEN
    International kategori
    Status
    Forslag om nyt arbejdsemne under udarbejdelse
    Komite
    Beskrivelse
    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.

    This European standard deals with the technical requirements to minimise the risks due to the hazards listed in clause 4, which can arise during operation and maintenance of fixed belt conveyors and systems as defined in 3.1 to 3.2.4 and designed for continuously conveying loose bulk materials from the loading point(s) to the unloading point(s). Requirements for electromagnetic compatibility are also covered. This standard applies to use in ambient air temperatures of -15_ C to + 40_ C. This standard does not cover : a) use in open cast lignite mining or use underground, such as in mines or tunnels ; b) use in public areas or for man-riding ; c) floating, dredging and ship mounted equipment ; d) conveyors requiring a high level of cleanliness for hygiene reasons, e.g. in direct contact with foodstuffs or pharmaceuticals ; e) conveyors using a moving belt with other than a continuous rubber or polymeric surface for the conveying medium ; f) transportation of the conveyor ; g) the design of the supporting structure which is not part of a conveyor (see 3.2) ; h) the effects of wind ; i) hazards resulting from handling specific hazardous materials, (e.g. explosives, radiating material) ; j) hazards resulting from contact with or inhalation of harmful fluids, gases, mists, fumes or dust ; k) biological and micro-biological (viral or bacterial) hazards ; l) hazards due to heat radiation from the materials handled ; m) hazards caused by operation in electromagnetic fields outside the range of EN 61000-6-2: 1999; n) hazards caused by operation subject to special regulations (e.g. explosive atmospheres) ; o) hazards caused by noise ; p) hazards caused by the use of ionising radiation sources ; q) hazards caused by hydraulic equipment. The safety requirements of this standard apply to equipment and systems placed on the market after the date of publication of this standard.

    Forslag om nyt arbejdsemne vedtaget
    Beskrivelse
    This document describes procedures for the testing of dyed paper and board intended to come into contact with foodstuffs. Some procedures depending on the foreseeable use of the material are given. Visual evaluation against a grey scale provides grading of the bleeding. NOTE: For samples having significant different sides, a migration can occur from one glass fibre to the other and could lead to wrong interpretation of the fastness of one side. These samples should be checked using large sampling procedure to prevent cross contamination of the glass fibre during the migration procedure. The procedure is described in annexe A. If lower limit of detection is required, this procedure could also be used.
