Foreword
This document (EN 12811-2:2004) has been prepared by Technical Committee CEN/TC 53 “Temporäre
Baukonstruktionen”, the secretariat of which is held by DIN.
This European Standard shall be given the status of a national standard, either by publication of an identical
text or by endorsement, at the latest by August 2004, and conflicting national standards shall be withdrawn at
the latest by August 2004.
This European Standard EN 12811 consists of the following parts under the general title: Temporary works
equipment:
- Part 1: Scaffolds - Performance requirements and general design
- Part 2: Information on materials
- Part 3: Load testing
Annex A is informative.
This document includes a Bibliography.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic,
Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania,
Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden, Switzerland
and United Kingdom.
Introduction
This European Standard represents a supporting standard for product standards produced by CEN/TC 53.
It takes into account the material-related comments on the following drafts obtained in the CEN-enquiry:
prEN 12810-1:1997, Façade scaffolds made of prefabricated components — Part 1: Product specifications.
prEN 12810-2, Façade scaffolds made of prefabricated components - Part 2: Particular methods of structural
design
prEN 12811:1997, Scaffolds — Performance requirements and general design.
prEN 12812:1997, Falsework — Performance requirements and general design.
prEN 12813:1997, Load bearing towers made of prefabricated elements — Methods of particular design and
assessment.
prEN 13331-1:1998, Trench lining systems — Part 1: Product specifications.
prEN 13331-2:1998, Trench lining systems — Part 2: Assessment by calculation or test.
prEN 13377:1998, Prefabricated timber formwork beams — Requirements, classification and assessment.
This standard is limited to the selection of types and grades of material from standards, which are either
international or European standards. However, in the field of temporary works equipment the use of other
materials can be indicated or even imperative.
The use of non standardised (new) materials can give advantage for particular components. But this use
prevents the marking of the product conforming in other respects to the product standard with the number of
the respective product standard.
The components of temporary works equipment are used for many years. There are components in the stores
of the users and on building sites which are made of materials corresponding to former national standards.
This standard does not intend to prevent neither the use of non standardised (new) materials nor the use of
components made of old materials.
It is beyond the scope and the competence of CEN/TC 53 to formulate regulations for non standardized new
materials and for old materials former standardized nationally.
In the absence of a European product directive for temporary works equipment, such regulations and their
mutual acknowledgement are reserved to the single European country.
For closing the gap until a European regulation is available, the following recommendations are given:
1. The single country could add a national foreword to this standard, which regulates the further use of
components, made of old materials for its jurisdiction.
2. The Working Groups of CEN/TC 53 could include a requirement in their product standards that also
products made partially of materials not covered by ISO or EN standards may have the number of the
product standard, if they are marked with an asterisk additionally and if the fact is recorded in the product
manual.
1 Scope
This European Standard provides guidance on where to find information on materials often used in temporary
works. It draws attention to a number of points that a designer should take into account.
The information given is limited to commonly used steel, aluminium alloys, cast iron, timber and timber based
materials.
Requirements are also given for welding, for limiting corrosion and other deterioration.
It is limited to the selection of types and grades of material from standards, which are either international or
European Standards.
