Vertical formwork - Part 1: Performance requirements, general design and assessment

This standard sets out the significant parameters which are relevant to the provision of formwork for all types of vertical concrete faces. For most parameters, it gives ranges of values from which a choice has to be made. It also gives some additional parameters for factory made panels which are part of a system and are assembled to create vertical formwork. Four groups are used to form a classification.

Foreword
This document (prEN 15113-1:2004) 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
The purpose of this European Standard is to sets out performance requirements for vertical formwork and to
provide a safe place of work with safe access suitable for the work being done. These are substantially
independent of the materials of which the vertical formwork is made. The standard is intended to be used as
the basis for enquiry and design.
As a number of options are given to suit different applications, a choice has to be made between the various
alternatives within this European Standard. All other requirements would be in an associated job specification.
Based on these requirements, a set of rules can be drawn up for a particular type of equipment. These may
be standard for general use, or specially prepared for a particular job.
This European Standard includes rules for structural design, which are of particular relevance to vertical
formworks of certain materials.
This standard does not cover the use of materials conforming to EN or ISO standards not still valid.
For access and working facilities for operatives, reference should be made to the requirements of EN 12811-1
but this standard also gives more specific details which will be needed in some cases.

1 Scope
This part of standard sets out the significant parameters which are relevant to the provision of formwork for all
types of vertical concrete faces. For most parameters, it gives ranges of values from which a choice has to be
made.
It also gives some additional parameters for factory made panels which are part of a system and are
assembled to create vertical formwork. Several groups are used to form a classification.
It gives guidance on design by the limit state method.
It does not specify the micro quality of the form face or any of the parameters of the concrete face which will
be revealed when the formwork is removed.
