The applicant concludes an agreement with the Technical Assessment Body for the conduct of the proceedings.

Unless otherwise provided for in the agreement, within two months from the initiation of the proceedings, the Technical Assessment Body presents the applicant with a written position regarding the application. In its position, the Technical Assessment Body specifies:

  • the type, subject, methods and scope of additional tests, calculations and classifications, together with a concise justification for their necessity,

  • a list and subject of additional documents and information required under separate regulations

– necessary to assess the performance characteristics of the construction product in relation to its intended use.

Obtaining the documents, information, test results, calculations and classifications referred to above is the responsibility of the applicant.

In the proceedings, the Technical Assessment Body recognises the results of tests and calculations performed by:

  • laboratories accredited in accordance with the Act of 13 April 2016 on Conformity Assessment and Market Surveillance Systems;

  • foreign laboratories, where this results from international agreements, and laboratories notified in accordance with Regulation (EU) No. 305/2011 of the European Parliament and of the Council of 9 March 2011 laying down harmonised conditions for the marketing of construction products and repealing Council Directive 89/106/EEC;

  • other domestic and foreign laboratories with which the Technical Assessment Body has concluded agreements on the mutual recognition of test and calculation results.

The Technical Assessment Body may also recognise, in the proceedings, test results and calculations provided by the applicant and performed by domestic or foreign laboratories other than those listed above.

When conducting the proceedings, the Technical Assessment Body:

  • assesses the performance characteristics of construction products, taking into account applicable separate regulations, including technical and construction regulations, as well as scientific principles and practical knowledge;

  • analyses the data received from the applicant in a manner ensuring a balanced assessment;

  • makes impartial decisions;

  • ensures the confidentiality of information obtained during the proceedings and maintains the secrecy of test and calculation results, design documentation and technology descriptions reserved by the applicant.

After obtaining the complete set of test reports, calculations, information and documents specified in its position regarding the application, the Technical Assessment Body issues the National Technical Assessment or refuses to issue it, providing justification for its decision.

Information on accredited laboratories is available on the website of the Polish Centre for Accreditation.

CONDITIONS FOR THE ASSESSMENT OF PERFORMANCE OF A CONSTRUCTION PRODUCT

The conditions for the assessment of performance of a construction product are developed on the basis of § 6(2) and § 7 of the Regulation of the Minister of Infrastructure and Construction of 17 November 2016 on national technical assessments (Journal of Laws of 2016, item 1968), with regard to construction products for which there are sufficient scientific grounds and practical knowledge to determine a uniform scope of the required level of performance characteristics.

The Conditions for Assessment are developed by a technical assessment body/national technical assessment body within the scope of product groups for which it is authorised to issue national technical assessments. In the case of construction products falling within the scope of more than one assessment body, the Conditions for Assessment are developed jointly by those bodies.

The provisions contained in the Conditions for the Assessment of Performance of a Construction Product are taken into account in the procedure for issuing a national technical assessment for a product covered by the Conditions for Assessment.
