European foreword
This document (prEN 131-9:2026) has been prepared by Technical Committee CEN/TC 93 “Ladders”, the
secretariat of which is held by DIN.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 14183:2003.
This document includes the following significant technical changes with respect to EN 14183:2003:
— standard integrated in the EN 131 series for ladders;
— all seating functions of step stools deleted;
— requirements and test methods aligned with EN 131-2 as far as possible;
— ladder type step stools added;
— determination of the friction coefficient in 6.10 modified and carried out on glass;
— compression security device test added as 6.11.
1 Scope
This document specifies the requirements for step stools. This includes design characteristics,
dimensions, materials, performance requirements, test methods and the declaration of suitability of use.
This document is not applicable to ladders and stepladders as defined by EN 131-1.
NOTE This document is applicable to both side ascendable ladder type step stools with an allowable standing
height up to 1 m. Both side ascendable step ladders with an allowable standing height greater than 1 m belong to
the scope of in EN 131-1.
This document is applicable to step stools designed for general professional and non-professional use.
This document is not applicable to step stools which by their design and instructions are intended and
limited only for a specific professional use and as a result are not for general professional or non-
professional use.
This document is not applicable to products intended for use by children falling under the scope of
CEN/TC 252 “Child care articles” or toys falling under the scope of CEN/TC 52 “Safety of toys”.
The products are intended to be used by one person only, requirements are based upon a maximum total
load of 150 kg.

4 Functional dimensions and designations
4.1 General
The drawings are examples only and products need not correspond. However, dimensions shall be
applied. Step stools shall be fitted with steps that are uniformly spaced to within a tolerance of ±2 mm.
All types of products covered by this document may be fitted with castors and wheels.
There shall be no gap between the projection of the steps to the ground (see Figure 3).
A platform shall have a minimum area of 600 cm and shall include a square of 200 mm × 200 mm, see
Figure 1.
Openings in platforms and steps shall not allow a ball of a diameter of 35 mm to fall through.
The design shall seek to minimize the existence of shearing and squeeze points and where they do exist
to minimize the shearing and squeezing effects as far as practicable.
NOTE Shear or squeeze points exist if the distance between two accessible parts relative to each other is less
than 18 mm and more than 7 mm in any position during movement.
The radius of the horizontal edges of platforms and steps shall be max 15 mm (see Figure 1) in order to
avoid slipping at the edges.
If the height of the step stool is more than 750 mm and the platform is less than 240 mm × 400 mm a
hand-/kneerail is required which shall b
