Introduction
This standard is a type C standard as stated in EN ISO 12100.
The machinery concerned and the extent to which hazards, hazardous situations and hazardous events are
covered are indicated in the scope of this standard.
When provisions of this type C standard are different from those that are stated in type A or type B standards,
the provisions of this type C standard take precedence over the provisions of the other standards, for
machines that have been designed and built according to the provisions of this type C standard.
While producing this standard it was assumed that:
a) only competent persons operate the machine;
b) components without specific requirements are:
1) designed in accordance with the usual engineering practice and calculation codes, including all
failure modes;
2) of suitable mechanical and electrical construction;
3) made of materials with adequate strength and of suitable quality.
c) harmful materials, such as asbestos are not used as part of the machine;
d) components are kept in good repair and working order, so that the required characteristics remain despite
wear;
e) by design of the load bearing elements, safe operation of the machine is assured for loading ranging from
zero to 100 % of the rated possibilities;
f) discussions have taken place between the user and the supplier concerning particular conditions for the
use and places of use of the machinery;
g) working area is adequately lit;
h) places of installation allow a safe use of the machine.

1 Scope
This standard applies to all types of S/R machines, restricted to the rails on which they travel within and
outside the aisles, which embody lifting means and may embody lateral handling facilities, for the storage and
retrieval of unit loads and/or long goods such as bar materials and/or for order picking or similar duties. Also
included is the transfer equipment used to change between aisles. Control of machines may range from
manual to fully automatic.
This standard does not apply to free ranging industrial trucks or robots.
References in this standard to racking, buildings and systems only apply where it is necessary to assess the
hazards and risks at their interfaces with S/R machines.
This standard deals with all significant hazards relevant to rail dependent storage and retrieval equipment,
when they are used as intended under the conditions foreseen by the manufacturer (see Clause 4).
This standard applies to machines and equipment that are manufactured after the date of issue of this
standard.
Illustrations of examples of machines and transfer equipment to which this standard applies are shown in
Annex A.
Safety requirements and/or measures in this standard apply to equipment used under indoor conditions.
However, additional risk assessments and safety measures need to be considered for uses in severe
conditions, e.g. freezer applications, high temperatures, loads, the nature of which could lead to a dangerous
situation (e.g. especially brittle loads, explosives), earthquake effects and also contact with foodstuff. Hazards
during decommissioning are not covered.
This European Standard also deals with the technical requirements for electromagnetic compatibility (EMC).
Noise emitted by these machines is not considered as significant but as a relevant hazard. This means that
the manufacturer of the machine is obliged to carry out noise reduction and indicate the noise level.
