CE marking for windows and external pedestrian doorsets - product standard EN 14351-1

Information service on product standard EN 14351-1 Windows and external pedestrian doorsets

As the product standard EN 14351-1:2006+A2:2016 or DIN EN 14351-1:2016-12 are harmonized standards, the Construction Products Regulation requests bindingly the CE marking for windows and external pedestrian doorsets. An corresponding CE marking is already obligatory for products such as hardware for emergency exit doors or single-axis hinges for fire safety. The uniform labelling of the essential characteristics of a product is regulated and the associated test methods are determined with the European CE mark. Therefore, in order to assist the industry at the implementation, ift Rosenheim, as a testing institute, developed an annotation as well as practice-oriented information and services.

 

Background on product standard and CE marking

An objective comparison as well as a product-neutral tender is possible with the standard EN 14351-1, as it orientates on the “performance principle”. This means that the products are evaluated according to their characteristics. These, on the other hand, have to be verified by an independent testing institute or by means of tables of the building standards and mentioned in the CE mark. The mandated characteristics, which require a evidence of performance in Germany, include amongst others: the resistance to wind load, the watertightness, the thermal transmittance (U value) at heated residential buildings according to Energy Conservation Regulations as well as the radiation properties of glass and the air permeability. Acoustic insulation, burglar intrusion and further properties can be demanded within the tender.

 

Aim of the product standard EN 14351-1 Windows and external pedestrian doorsets

The aim of the product standard is an European uniform and material-independent specification of the characteristics and performance classes of windows and external pedestrian doorsets as well as the necessary tests and verifications. Planner, consumer and manufacturer obtain with this product standard the basis for performance-oriented and function-orientated evaluation of windows and doors. Manufacturer can declare that their products meet the uniform technical requirements and specifications. In addition, house owners and planner have the possibility to compare the products on basis of the characteristics and to select the product that meets their requirements. In order to support the development of individual products, an abandonment of the standardised constructions is accompanying the CE marking.

The CE marking for windows and external pedestrian doorsets became mandatory throughout Europe with the end of the coexistence period (01.02.2010). Exceptions are only permitted within Article 5 of the Construction Products Regulation.

 

Scope of DIN EN 14341-1

The product standard EN 14351-1 applies for the following elements:
  • Windows
  • French windows
  • Roof windows
  • Composite elements for the installation in wall openings and suitable roof windows

This also includes associated:

  • Hardware
  • Sealants
  • Glazed openings
  • Built-in roller shutters and roller shutter boxes
  • Manually operated external doors with integrated fanlights and adjoining side elements

The standard does not apply for:

  • Windows and doors with specifications for smoke leakage and fire resistance
  • Rooflights
  • Curtain walls
  • Industrial doors and gates
  • Internal doors
  • Revolving doors
  • Windows in escape routes
The CE mark does not indicate a quality mark, as only windows in new condition are tested according to the standard. The warranty of a sufficient fitness for use lies in the direct responsibility of the manufacturer. The manufacturer can give references, make personal recommendations or perform a quality certification, e.g. by the RAL Quality Associations or ift Rosenheim. In general, DIN EN standards are primarily technical recommendations like other DIN standards, without direct legally binding nature. This depends on whether it is about a civil or building regulation point of view.

 

The most important operational “homework” of CE marking are the following points (see also ift-Check list "The route to CE marking"):

  • Description of product and the associated performance characteristics
  • Compilation of available test reports and examination of the conformity with the test and classification standards mentioned in the product standard
  • Selection of representative product lines and test specimen
  • Assignment of the type-testing (TT) by a notified body
  • Introduction and/or assessment of factory production control
  • Issuing of Declaration of performance and CE marking

 

Basis of the CE mark

The basis for the CE mark is the Construction Products Directive (CPD), which was passed already in 1988, to regulate uniformly the manufacturing, marketing and use of construction products in Europe. However, the technical rules of the member states are standardise, whereas the regulation of the specifications takes place nationally. The product standards comprise the mandatory fundamental product requirements. Therefore, the classification and the test methods are defined in the EN standards. The national implementation of the European CPD behooves the Construction Products Law.
