Where fixed means of access are needed.

Input the mathematical load formulas found within the standard into engineering design software or CAD tools. This ensures that the structural integrity of fabricated guard-rails matches the safety factors required by the European harmonized standard. Procurement Specifications

Part 3 of the ISO 14122 series focuses on three main components:

Some websites offer “free” PDF files of the – but these are no longer valid . Using withdrawn versions may cause serious safety gaps and non‑compliance with the EU Machinery Directive. din en iso 14122-3 pdf

This standard applies to:

For 38°, the tread depth (going) should be approximately 250–300 mm. Total horizontal run = 14 x 250 mm = 3500 mm.

Structures designed to reach machine operating and service points.

| Mistake | Consequence | Solution | |---------|-------------|----------| | Using open risers on stepladders | Foot or tool slips through, causing fall | Use closed (solid) risers for angles >45° | | Inconsistent step height (even 10 mm variation) | Tripping hazard | Use a jig or CNC fabrication | | Forgetting toe plates on guardrails | Objects fall on workers below | Add 100 mm min. toe plate | | Handrail not continuous | Loss of balance at landing | Extend handrail across landing | | Slip resistance too low (R9 on oily steps) | Slips in wet conditions | Use R12 or R13 surface (chequer plate or grit strip) |

ISO 14122‑3 is . It is part of a four‑part series that together covers all aspects of permanent access to machinery:

The standard applies to that are part of a stationary machine, as well as to non‑powered adjustable parts (such as foldable or slidable components) of those fixed means of access. “Fixed” means of access are defined as those mounted by screws, nuts, welding or similar methods so that they can only be removed with tools.

A: Spiral stairs are partially covered. The standard provides specific additional requirements for tread width at the inner radius (minimum 120 mm). Consult the standard carefully.
