This European Standard gives guidelines for operational aspects relevant to structural safety of storage
systems. Such systems operate with heavy mechanical handling equipment working in close proximity to
static storage equipment. This European Standard minimizes the risk and consequences of unsafe operation
or damage to the structure. Some other forms of storage equipment are only partially covered and further
consideration, beyond the scope of this European Standard, can be required.
This European Standard gives guidance in conjunction with prEN 15512, EN 15620, and EN 15629 to ensure
that the specifier, user and designer are aware of the constraints in each other’s area to allow a safe design to
be produced.
This European Standard specifically excludes storage equipment manufactured form materials other than
steel (except for certain accessories) and equipment intended to be used for domestic storage purposes

This European Standard supplies guidelines for the technical specification to allow the design of racking and shelving in its various forms such as adjustable pallet racking (APR), crane serviced racking, drive-in racking (DIR), cantilever racking and shelving systems, including their various forms of construction, using manually operated and controlled mechanical handling systems. Some other forms of storage equipments are only partially covered and further consideration, beyond the scope of this document, may be required.
This European Standard gives guidance for the specifier of storage systems to coordinate suppliers of all equipment including individual responsibilities.
This European Standard does not cover storage equipments manufactured from materials other than steel (except for certain accessories) and equipment intended to be used for domestic storage purposes.

This European Standard specifies tolerances, deformations and clearances that pertain to the production, assembly and erection of pallet racking including the interaction with floors. These tolerances, deformations and clearances are important in relation to the functional requirements and ensuring the proper interaction of the handling equipment used by personnel, trained and qualified as competent, in association with the specific type of racking system. The interaction conditions are also important in determining the reliability of the storage system to ensure that the chance of an industrial truck impact, pallet impact or a system breakdown is acceptably low. The design safety philosophy given in prEN 15512 is based upon compliance with this standard.
This European Standard gives guidance for a variety of issues including operating clearances, manufacturing, assembly and erection tolerance limitations, as well as deflection or strain deformation limitations under loads. This European Standard is limited to single deep adjustable beam pallet racking operated with industrial trucks or stacker cranes. Drive-in, double deep and satellite systems will be considered for inclusion in the document in the future. This European Standard specifically excludes the tolerances and deformation of the trucks and stacker cranes. It is the responsibility of the truck or stacker crane supplier and the client or user to ensure that the tolerances, deformations and clearances, as quoted in this European Standard for the racking systems, are acceptable for the safe operation of the overall system.
This European Standard gives guidance to be used in conjunction with the latest information from the truck and stacker crane suppliers regarding turning radii, tolerances and deformations of the truck and stacker cranes.

This European Standard specifies the structural design requirements applicable to all types of adjustable beam pallet rack systems fabricated from steel members intended for the storage of unit loads and subject to predominantly static loads. Both un-braced and braced systems are included.
This European Standard gives guidelines for the design of clad rack buildings where requirements are not covered in EN 1993. The requirements of this European Standard also apply to ancillary structures, where rack components are employed as the main structural members. This European Standard does not cover other generic types of storage structures. Specifically, this European
Standard does not apply to mobile storage systems, drive-in, drive-through and cantilever racks or static steel shelving systems, nor does this European Standard establish specific design rules for the assessment of racking in seismic areas.
