EN 1090-1

Background

From 1st of July 2013 onwards, Regulation (EU) No 305/2011 - EU Construction Products Regulation - applies to the marketing of construction products.

The Regulation lays down the conditions for the placing on the market (first making available on the market) and the provision of construction products (any supply of a construction product for distribution, or for use on the Union market), as well as the CE marking.

According to the provisions of the EU Construction Products Regulation (EU CPR) it is up to the manufacturers and the economic operators on an equal footing such as importers or dealers that are considered manufacturers, to decide on its own responsibility if their product falls within the scope of application of the EU CPR and whether the requirements for the marketing of harmonized construction products are met. The following details do not relieve economic operators of their own responsibility and cannot replace individual legal advice in individual cases.

The manufacturers of steel structures and aluminum will be obliged from 1 July 2014 to do CE marking according to EN 1090-1 (Execution of steel structures and aluminum structures - Part 1: Requirements for conformity assessment of structural components), this fulfillment allows the placing on the market of construction products within the EU.

Summary

This series of standards deals with the execution of steel structures and aluminum structures.
So far, three parts are published:

Part 1 - Requirements for conformity assessment of structural components
This describes which properties of products are to declare which requirements apply accordingly and what options are available to meet these. In addition it describes the responsibilities of manufacturer and conformity assessment body (CAB).

Part 2 - Technical requirements for steel structures
Part 3 - Technical requirements for aluminum structures

Here different requirements are described as a function of different execution classes. The design class with the lowest requirements is the design class EXC1 and those with the highest EXC4. In addition to this also requirements depending on the corresponding design class, for example for the welding supervisory personnel, etc. are listed.

Process of preparation

The manufacturer shall qualify in advance its products through Initial Type Test (ITT) or Initial Type Calculation (ITC) and implement a system of internal control of production

·         Initial type testing (ITT) to assess the manufacturing capabilities.

·         Initial type calculation (ITC) to assess the structural design capabilities, where the manufacturer shall declare structural characteristics governed by design of the component;

·         FPC system shall consist of written procedures, regular inspections and tests and/or assessments and the use of results to control the component’s constituent products, equipment, the production process and the manufactured component.

Certification

The manufacturer shall certify its FPC (Factory Production Control) through the involvement of a Notified Body.

The Notified Body issues the certificate of conformity of the factory production control that allows the manufacturer to draw up the Declaration of Performance (DoP) and affix the CE marking on its products and market them, as required by Regulation (EU) 305/2011.

Two assessment activities:

  • ·     Initial inspection of both the factory and the factory production control system;
  • ·     Continuous surveillance and assessment of the FPC system.
