The activities carried out by the The Institute for Materials Testing within the assessment and verification of constancy of performance of construction products according to a certain system for assessment and verification of constancy of performance – 1+, 1 and 2+, are defined in the Rulebook on assessment and verification of constancy of performance of construction products and the Law on Construction Products.
Submiting of an application
The Application for certification/ assessment and verification of the constancy performance for certain construction product is submitted on the official form of the certification body (STZ 51, Application for certification ), whereby the client confirms that he agrees with the terms of certification. Along with the application for certification, the client is obliged to submit all documents, which, depending on the technical specification, require a certification body.
