As the angle increases beyond 45°, a standard stair transitions into a steeper stepladder, bringing different design constraints.

: The clear width should ideally be 800 mm, though it may be reduced to 600 mm or even 500 mm in restricted environments. Head-height : A minimum vertical clearance of is required above the pitch line. Load Resistance : Steps must withstand a concentrated load of applied over a 100 mm x 100 mm area at the nosing. dqo52087pnd5x.cloudfront.net 2. Guard-rails

In German, it is referred to as:

Provides precise formulas, tables, and figures for designing stairs and railings, such as the relationship between rise, going, and slope. How to Obtain the Official PDF

However, manufacturers must also use (choice of fixed means and general requirements) as a companion standard to achieve full compliance. din en iso 14122-3 pdf

Are you designing for a or retrofitting an existing one?

Failing to design industrial platforms to ISO 14122-3 standards introduces severe liabilities:

Part 3 focuses on specific structural elements that operators use to change elevation or safely navigate high working zones:

A knee rail is required at roughly half the height. Toe Board: A toe board ( height) must be installed to prevent objects from falling. Why You Need the DIN EN ISO 14122-3 PDF Acquiring the official, up-to-date PDF is crucial for: As the angle increases beyond 45°, a standard

≥45∘is greater than or equal to 45 raised to the composed with power 75∘75 raised to the composed with power Single flight height is limited to (compared to in older versions). Overlap ( ): The overlap between steps must be at least 3. Guard-rails (Handrails)

This document is essential for:

For CE marking compliance in Germany, the version is the authoritative document, as its application provides a "presumption of conformity" with the Machinery Directive.

Staircases and public access ways inside commercial or residential buildings (which are governed by local building codes, such as DIN 18065 in Germany). Mobile elevating work platforms (MEWPs). 3. Dimensional Requirements for Stairs Load Resistance : Steps must withstand a concentrated
