What is BS EN 15620 about?  
BS EN 15620 discusses about Steel static storage systems.
BS EN 15620 specifies tolerances, deformations, and clearances that pertain to the production, assembly and erection, and performance under a load of pallet racking and cantilever racking. 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 mechanical handling equipment impact, pallet impact or a system breakdown is acceptably low.
BS EN 15620 is limited to:
- Single deep adjustable beam pallet racking operated with industrial trucks
- Single and double deep adjustable beam pallet racking operated with stacker cranes
- Drive-in and drive-through racking systems operated with industrial trucks
- Cantilever racking systems operated with industrial trucks
Note1: BS EN 15620 does not apply to specialized types of equipment such as automated trucks, mini load, satellite systems, systems involving the use of articulated trucks, trucks using intrusive stacking methods or industrial truck serviced rack-clad buildings.
Note 2:BS EN 15620 specifically excludes the tolerances and deformation of the industrial trucks, stacker cranes, and floors.
Who is BS EN 15620? 
BS EN 15620 on Tolerances, deformations, and clearances of steel static storage systems is applicable to: 
- Manufacturers of storage systems
- Warehouse workers
- Designers of storage systems
- People working in the retail industry
- End consumers
Why should you use BS EN 15620?  
Racking systems are commonly used in warehouses, industries, and large retail stores to store goods. It is important for the specifier in cooperation with the client or user to ensure that the tolerances, deformations, and clearances, as quoted in this document are acceptable for the safe operation of the overall system considering all factors of influence and the user informed by means such as operating instructions.
The interaction conditions are also important in determining the reliability of the storage system to ensure that the chance of mechanical handling equipment impact, pallet impact or a system breakdown is acceptably low.
The specifier can carry out appropriate design/calculations to vary some of the parameters provided that an equivalent safe operation is achieved.
In order to have reliable state of the art guidance for those involved in designing these products and due to the differences in the shape of the structural components, detailing and connection types, additional technical information to the Euro codes is required.
BS EN 15620 specifies the requirements for the safe operation of pallet racking. The design, construction, and installation of steel static storage systems should conform to BS EN 15620.
BS EN 15620 gives guidance to be used in conjunction with mechanical handling equipment and floor information.
What’s changed since the last update? 
BS EN 15620:2021 supersedes BS EN 15620:2008, which is withdrawn.
BS EN 15620:2021 includes the following significant technical changes with respect to BS EN 15620:2008:
- Floor tolerances have been removed
- Tolerances for drive-in racking and cantilever racking have been added
- Tolerances for crane racking have been removed
- The classification system for racking operated by industrial trucks has been removed
