No. The 2002 edition (DIN EN ISO 14122‑3:2002‑01) together with its amendment A1:2010‑12 has been by the 2016‑10 edition. Using the withdrawn version is not acceptable for machinery placed on the market after 2016, as it does not reflect current safety requirements and the updated Machinery Directive.
| 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) |
DIN EN ISO 14122‑3 is a . The relationship works as follows:

The ISO 14122 series is divided into four distinct parts, each covering a specific aspect of permanent industrial access:
Your does not stand alone. It references:
Steps must overlap by at least 10 mm to prevent feet from slipping through the open gaps.

One of the most critical sections of the PDF concerns fall protection.
As a , it provides specific safety solutions applicable to a wide range of machinery. When integrated with an industrial machine, compliance with this standard provides a "presumption of conformity" with the Essential Health and Safety Requirements (EHSR) of the European Machinery Directive (and the updated Machinery Regulation). The Four Parts of EN ISO 14122
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. Ensuring secure access to machinery
a machine’s footprint?
At least one intermediate knee rail must be installed. The clear space between the top rail and knee rail, or knee rail and toe-plate, must not exceed 500 mm.
In industrial environments, safety is non-negotiable. Ensuring secure access to machinery, platforms, and elevated workstations is a primary concern for plant operators, safety engineers, and designers. The standard is the essential technical guideline for the design, construction, and installation of permanent means of access to machinery.
