For the safe release and marking of building materials to the market;
- Product Safety and Technical Regulations Law 7223
- 2011/305/EU Building Materials Regulation
- Regulation on the Criteria to Which Building Materials Will Be Subject
- CE Marking Regulation
- Regulation on Conformity Assessment Bodies and Notified Bodies These are the regulations required to be well known and
Building materials: It refers to all materials or tool materials that
are produced and presented to the market for permanent use in all kinds of construction works or in any part of these works, and the performance of which affects the performance of construction works related to the basic requirements.
Performance of building materials: Expressing the performance of the material in terms of its basic characteristics as a level, class, or definition.
Safe product: A product that is considered to provide a high level of protection for human health and safety, including the duration of use and the requirements for service, installation and maintenance, where applicable, under normal and reasonably foreseeable conditions, the use of which does not carry risks or carries minimal risks specific to the use of the product.
Products covered by the Building Materials Regulation Conformity verification systems have been determined by the European Union Commission decree.
The Commission decree establishes the duties applicable to our country and other EU countries, which should be carried out among the manufacturer and certifier (Approved Organization or Compliance Assessment Body) in the name of eligibility confirmation systems for building materials products according to the risk group.
Commission decrees describe responsibilities and product risk group. According to the regulations, the manufacturer is responsible for the safety of the product and for meeting the standard requirements and the requirements of the regulations.
Within the framework of these tasks, compliance confirmation systems (System 1, 1+, 2+, 3, and 4) are listed based on the degree of risk and group in product groups that will directly impact human health. It is necessary to ensure that the products in system 1, system 1+ and system 2+ are constantly controlled by a third party by the certification body.
Certification bodies serving within the framework of these confirmation systems (conformity confirmation system; products included in System 1, 1+, 2+ and 3) are authorized by the Ministry of Environment, Urbanization and Climate Change after being audited and accredited by the Accreditation Agency (TÜRKAK). After being published in the European Union Official Gazette, the eligibility assessment service is carried out.
The Authorized Certification Bodies are constantly supervised by TÜRKAK and the Ministry each year.
Compliance Assessment Bodies regularly audit manufacturers that produce products covered by system 1, 1+, 2+ annually.
Manufacturers, on the other hand, must continuously experiment and maintain factory production control. Compliance Assessment Bodies strictly control the products, in particular, that are within the scope of system 1+.
Unannounced samples are taken at least 6 times a year by the certification body and the accredited laboratories perform the tests according to the TS EN ISO 17025 Standard.
Samples are taken from the production site by impartial and independent trained samplers. 3 samples are taken for the same type of product. These samples are sealed and encoded. Of these, 1 is being tested by the manufacturer, 1 is being tested by the compliance assessment body, and 1 is being taken as a witness sample.
Special code is provided for the samples taken. Samples are delivered to accredited laboratories with the special code provided. Laboratories perform their tests with the code given without knowing who the sample belongs to and make their reports with the code.
The Compliance Assessment Body compares the tests it performs at least 6 times a year with the tests performed by the manufacturer and evaluates their eligibility. Likewise, all tests are evaluated annually in statistically specific programs.
Within the scope of system 2+, factory production control is constantly audited annually. It is being checked whether the manufacturer meets the standard terms of its tests and factory production control is being evaluated.
Within the scope of system 3, manufacturers use the safety mark of products by conducting tests to authorized accredited laboratories.
Within the scope of system 4, manufacturers conduct their tests according to the relevant product standard and use the declaration and safety mark according to the product performance by installing the factory production control system.
The concrete product in particular is covered by the G mark by national regulation. For the first-type test analysis of the product produced according to the concrete class, 9 cubed samples are taken from each batch individually. The samples taken are encoded with special codes. Coded samples are tested with code in laboratories. With the factory production control carried out every year, the manufacturer’s laboratory infrastructure, personnel competence, process competence, quality infrastructure such as input control, sales, purchasing, training are regularly checked.
Samples are taken from the samples poured at the construction site without informing the manufacturer at least 3 times a year, and the tests are carried out by authorized laboratories with the codes given on regular basis.
In this way, it is ensured that the products are offered for safe use by using the CE mark or G mark, and the standard conditions and regulatory requirements of the products.
It is the manufacturer’s responsibility to present the products to the market with the CE mark and the G mark. The responsibility of manufacturers to provide the standard requirements of their products is mandatory by legislation.
In the certification system, it is crucial that samples represent production and samples are taken unannounced neutrally. It is crucial that the samples are encoded and tested in the lab and the lab does not know to whom samples belong.
Certification bodies are also required to meet and implement their standard requirements one-on-one.
In this way, safe products that meet the standard conditions are presented to the market and their use is ensured. Market surveillance by the competent authority (Ministry) for products put on the market is also a regulatory requirement.
Trilateral liability from regulation ensures safe products are held on the market by CE and G mark. Failure to fulfill the duties by the trilateral responsibilities (Manufacturer, Ministry and Conformity Assessment Agency) causes unsafe products to be placed on the market.
It is undesirable to have unsafe products on the market and should not be allowed to do so. The use of safe products is ensured by performing the trilateral responsibility seamlessly and continuously in a loop.
