This directive applies to "construction materials", which are covered by any products produced for permanent use in construction works, including buildings and civil engineering works. One of the aims of the regulation is to determine the rules of declaration of performance about the basic properties of building materials and to determine the principles of adhering the CE mark to building materials.
Manufacturers are obliged to apply the CE mark to all construction materials within the scope of the product-specific European Technical Assessment. The Building Products Directive requires constant control of the declared performance of building products. For example, the performance of building materials under fire conditions is important to ensure the compatibility of products. Building materials must meet basic health and safety requirements.
In the basic requirements of the regulation, general purposes for construction works with regard to health and safety are set out:
* Mechanical strength and balance,
* Fire safety,
* Hygiene, health and environment,
* Usage safety,
* Protection from noise,
* Energy saving and heat retention.
The Construction Materials Directive has been prepared in order to remove trade barriers created by technical specifications and to ensure the free movement of construction products within the borders of the European Union. With this directive, uniform evaluation methods have been established for the performance of building products in the European Economic Area. These methods are used by public institutions, architects, engineers and contractors when explaining the performance of products, presenting products to consumers, and ing products suitable for their use in construction works. Declaration of performance or declaration of conformity to the European Union is a prerequisite for affixing the CE mark on the product. In order to make a statement of performance, the manufacturer must rely on an authorized laboratory report or an organization report certified by a third party. By signing the declaration of performance, the manufacturer is responsible for the performance of the entire production.
In cases where the products must bear the CE mark, the following should be included in addition to this mark:
* Manufacturer´s name or trademark,
* When necessary, the last two digits of the year the CE mark was affixed,
* Number of the EC certificate of conformity,
* Identification number of the notified body involved in the production control process,
* Information about the properties of the product specified in the technical specifications.
The manufacturer can adapt the CE mark on the product based on the Building Products Directive or other directives. For example, the CE marking for low voltage cables can be based on the Low Voltage Directive requirements. While initial inspection, continuous surveillance, type tests and inspection tests are among the duties of the notified body, factory product controls, type tests for certain product levels and declaration of performance are among the duties of the manufacturer.
Conformity Assessment Process
European Technical Approval Guidelines must be in force for CE marking to be affixed to equipment covered by the Construction Products Regulation. Without standards and ATOK, CE marking cannot be made even if a product is a building material. In the Construction Materials Regulation, all conformity assessment systems according to product groups are defined by Council Decisions. In these systems, the duties of the Manufacturer and Notified Bodies are defined separately in 4 systems.
Certification of Conformity
SYSTEM 1 & 1+ Level Products; Initial type test of the material; first inspection of factory and FÜK; Continuous surveillance of FÜK; testing of samples taken.
SYSTEM 2 & 2+ Level Products; Certification of FÜK; Continuous surveillance, evaluation and approval of FÜK.
SYSTEM 3 Level Products; Initial type testing of the material (by the approved laboratory).
SYSTEM 4 Level Products; No notified body is required, all tasks belong to the manufacturer.
The decisions of the European Commission describe the mandatory procedures to be followed in the conformity assessment for each product or product group. A manufacturer can produce a construction material in accordance with harmonized European standards or accepted national standards and then follows the conformity assessment procedure established for that product.
Conformity Assessment Procedures
* First type testing of the product by the notified body or manufacturer,
* Testing of samples taken from the factory according to the test plan previously specified by the notified institution or manufacturer,
* Inspection-testing of samples taken from the factory, marketed products or construction site by the notified institution or manufacturer.
* Testing of samples taken from the party that is kept ready to be sent by the notified institution or manufacturer,
* Providing Factory Production Control by the manufacturer,
* Initial audit of factory and factory production control by the notified body;
* Continuous surveillance, supervision and inquiry of factory production control by an approved institution.
