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).

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
