Foreword
This document (prEN 16031:2009) has been prepared by Technical Committee CEN/TC 53 “Temporary works
equipment”, the secretariat of which is held by DIN.
This document is currently submitted to the CEN Enquiry.
Introduction
Whilst this European Standard deals with the more common types of adjustable telescopic aluminium props in
use, it is not intended to prevent development of other types of props. For example, props may have hinged
ends or other length adjustment devices or be made of other materials. Whilst such props cannot comply with
this European Standard it is recommended that the principals of this European Standard should be considered
in the design and assessment of such props.
This European Standard is a product standard primarily for use in the field of falsework and formwork
standardized in EN 12812.
The specified values for load bearing capacity listed in this European Standard are figures for classification.
For site use γ and γ can be found in EN 12812

1 Scope
This European Standard specifies materials, design requirements, designation, corrosion protection
alternatives, together with assessment methods using both calculations and testing for adjustable telescopic
aluminium props which are intended for use on construction sites . Inner and outer tube of props are made in
aluminium or aluminium and steel
It specifies eleven classes of nominal specified values for strengths for adjustable telescopic aluminium props
each having a series of maximum extended lengths.
