Introduction
This European standard is a type C standard as defined in !EN ISO 12100-1".
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 systems and
components that have been designed and built according to the provisions of this type C standard.
While producing this standard it was assumed that:
- only trained persons operate the machine;
- parts without specific requirements are:
a) designed in accordance with the usual engineering practice and calculation codes, including all failures
modes;
b) of sound mechanical and electrical construction;
c) made of materials with adequate strength and of suitable quality;
d) made of materials free of defects;
- harmful materials, such as asbestos are not used as part of the system and components;
- components and system are kept in good repair and working order, so that the required characteristics remain
despite wear;
- by design of the load bearing elements, a safe operation of the system and components is assured for loading
ranging from zero to 100 % of the rated possibilities and during the tests;
- the ambient air temperature is maintained between - 15 °C and + 40 °C;
- the relative humidity is kept between limits which do not impede the safe working of the system and
components;
- the components (see clause 3.4) are not exposed to external vibration;
!deleted text"
- a negotiation takes place between the user / installer and the manufacturer concerning the particular
conditions for the use and places of use of the machinery;
- the working area is adequately lit;
- the places of installation allow a safe use of the system;
- safety data sheets on the bulk materials to be conveyed are provided by the user / installer and are part of the
design criteria.
EN 617, EN 618 and EN 620 may need to be considered for a complete continuous handling system (machine).
