Foreword
This document (EN 620:2002) has been prepared by Technical Committee CEN /TC 148, "Continuous handling
equipment and systems", the secretariat of which is held by AFNOR.
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by endorsement, at the latest by October 2002, and conflicting national standards shall be withdrawn at the latest
by October 2002.
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 annex ZA and ZB, which is an integral part 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, Czech Republic, Denmark, Finland,
France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal, Spain,
Sweden, Switzerland and the United Kingdom.
This draft standard forms part of a series of five draft standards the titles of which are given below:

EN 617 "Continuous handling equipment and systems – Safety and EMC requirements for the equipment for
the storage of bulk materials in silos, bunkers, bins and hoppers" ;

EN 618 "Continuous handling equipment and systems - Safety and EMC requirements for equipment for
mechanical handling of bulk materials except fixed belt conveyors” ;

components for pneumatic handling of bulk materials”.
In this standard Annex A is normative, Annexes ZA and ZB are informative.
Introduction
This European Standard is a type C Standard as stated in EN 1070:1998.
The products concerned and the extent to which hazards are covered are indicated in the scope of this standard.
While producing this standard it was assumed that :

negotiations occur between the manufacturer and the purchaser concerning particular conditions for the use
and places of use for the machinery related to health and safety ;

only suitably trained persons will operate this machinery ;

the machinery will be kept in good repair and working order, in accordance with the manufacturer's
instructions, to retain specified health and safety characteristics throughout its working life ;

the place of installation is adequately lit.

the place of installation will allow safe use of the machinery;

by design of the load bearing elements, the safe operation of the system and components is assured for
loading ranging from zero to 100 % of the rated capacities and during testing;

all parts of the machinery without specific requirements, will be :
a) made from materials of adequate strength and durability and of suitable quality for their intended purpose;
b) of sound mechanical construction ;
c) designed in accordance with the usual engineering practice and engineering codes, taking account of all
failure modes and incorporating appropriate safety factors.
EN 617, EN 618 and EN 741 need to be considered for a complete continuous handling system (machine).
1 Scope
1.1 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.
1.2 This standard applies to use in ambient air temperatures of -15 C to + 40 C.
1.3 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.
NOTE Directive 94/9/EC concerning equipment and protective systems intended for use in potentially
explosive atmospheres can be applicable to the type of machine or equipment covered by this European
Standard. The present standard is not intended to provide means of complying with the essential health and
safety requirements of Directive 94/9/EC.
