Document Title: Self-supporting metal sheet for roofing, external cladding and internal lining - Product specification and requirements
German Designator: DIN EN 14782
Date: March 2006
National Foreword Designations:
This standard has been prepared by CEN/TC 128 'Roof covering products for discontinuous laying and products for wall cladding' (Secretariat: Belgium).
The responsible German body involved in its preparation was the Normenausschuss Bauwesen (Building and Civil Engineering Standards Committee), Technical Committee 005-02-06 AA Dacheindeckungsprodukte aus Metallblech (Sp CEN/TC 128/SC 7).
This standard sets out requirements and test methods for factory-made self-supporting metal sheet for roofing and cladding. The standard applies only for products for non-loadbearing applications. 'Permanent loading' of products as in this standard only covers the selfweight of the sheet, using supports at intervals of 1 m or less.
EN 14872 is a product standard, and does not affect the specifications of the DIN 18807 series of standards.
Mandate: Prepared Under European Commission Mandate 121 and Mandate 122
Purchase From DIN: DIN EN 14782
View Standard: Documents have been removed from view until resolution of pending litigation. Currently available standards are listed in Table 01.
EN 14782 is a 2006 standard for self-supporting metal sheets used in construction for non-structural applications. The pieces are used for roofing, wall cladding and lining, ceilings, and soffit applications.
The standard builds on top of and relies on a large number of basic standards. For example, the definition of the metal sheets relies on EN 506:2000 (specifications for copper or zinc sheets), EN 508-1:2000 (steel sheets), EN 508-2:2000 (aluminum sheets), and EN 508-3:2000 (stainless steel sheets).
The standard covers a number of properties of these metal sheets, including mechanical resistance, water permeability, and fire performance. If a product is covered by this standard, they are put on a “deemed to satisfy without the need for testing” list, meaning that a construction project may use the product in a number of categories. For example, clause 5.2, “reaction to fire,” specifies that products may be deemed to “satisfy the requirements for performance Class A1 of the characteristic reaction to fire in accordance with the provisions of EC Decision 96/603.”
The genesis of this standard is Council Directive 89/106/EEC . It was passed on December 21, 1988, and details the “approximation of laws, regulations and administrative provisions of the Member States relating to construction products.” The Directive is specifically concerned with member state regulations in the field of construction, and provides for the joint goals of building safety and the removal of technical barriers to trade in the construction field.
Based on the Council Directive, the European Commission created two mandates:
Both mandates are extremely specific about the areas to be covered, laying out a number of criteria that map to the section of the standard that was produced. As part of the mandate, national regulatory authorities and the Commission were intimately involved in monitoring the creation of the standard, working closely with the national delegations that participate in the CEN/CENELEC process.
The standardization activity was conducted under a Commission-approved work program, and specific provisions were made for public circulation of draft and other due process considerations typical of any regulatory process. The work program
submitted had to include very detailed information, such as a list of all supporting documents relevant to test methods, definitions of the characteristics and forms of materials to be covered, a timetable for finalization, and specification of who exactly will be carrying out the work.
The final product reflects the careful monitoring of this process by the Commission. Annex ZA of EN 14782 lays out a one-to-one correspondence between the requirements of the mandate and the specific sections of the standard. It also lays out the form of the CE conformity marking, including how the material react to fire, the classes of external fire performance, and the resistance of the materials to concentrated force.
Once the standard has been approved by both CEN and the Commission, the forward specifies that “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 July 2006, and conflicting national standards shall be withdrawn at the latest by July 2006.”
