Din En Iso 14122-3 Pdf 🆕 Tested & Working

Does not apply to powered access like lifts, elevators, or escalators.

DIN EN ISO 14122-3 is part of a four-part international standard. It focuses specifically on attached to permanent machinery. The complete standard series includes:

The standard is highly technical, providing specific measurements and geometric constraints to minimize the risk of falling, slipping, or tripping. Engineers and designers must consult the PDF documentation to verify exact tolerances, but the key areas of focus include:

The minimum clear width of a staircase should be 600 mm, though 800 mm is highly recommended for regular two-way industrial traffic. din en iso 14122-3 pdf

Before signing off on a factory layout or platform design, verify your schematics against this quick reference checklist derived from the standard: Structural Element Checkpoint Requirement Compliant? (Y/N) Is the top rail at least 1100 mm high? Toe-plate Is there a 100 mm barrier to prevent falling objects? Stair Riser Does the riser height ( ) comply with the Clearance Is there at least 2300 mm of overhead headroom? Access Gate Are all fence openings protected by a self-closing gate?

While users often search for a "DIN EN ISO 14122-3 PDF," it is important to note that this is a copyrighted technical standard. Official copies can be purchased from authorized distributors like DIN Media or the ISO Store . Scope and Application Does not apply to powered access like lifts,

(the latest version) specifies requirements for non-powered stairs, step ladders, and guardrails that provide safe access to machinery. It applies to permanent access routes where the vertical rise exceeds 500 mm or where there is a risk of falling.

Available through local national standards institutions (e.g., DIN, BSI, AFNOR).

Compliance requires verification through physical testing or finite element analysis (FEA). The complete standard series includes: The standard is

This standard is part of the ISO 14122 series, intended to be used in conjunction with (which defines general requirements for access), and is essential for adhering to the European Machinery Directive (2006/42/EC). Scope of the Standard The standard applies to:

In industrial environments, access to machinery is not a luxury—it is a necessity. However, every year, thousands of workplace accidents occur due to poorly designed stairs, ladders, and platforms. To combat this, the International Organization for Standardization (ISO) and the European Committee for Standardization (CEN) developed the series, which has been adopted as DIN EN ISO 14122 in Germany.

The standard specifies dimensional requirements for industrial stairs, including step width, riser height, going (tread depth), and the angle of inclination. It also covers landings, handrails and the clearances required for safe passage.

To ensure natural human stride cadence, the dimensions of the rise ( ) and going ( ) must satisfy the following formula:
