QB

In order to simplify the current certification scene in the construction sector and maximize the legibility of benchmarks for the quality, performance and reliability of products, services and stakeholders, the CSTB is launched QB - Quality in Building at the end of 2015.

The excellence and impartiality of the certification process and the level of certification requirements form the basis of the technical added value of QB certification, thus contributing to the continuous reliability of product quality.

The QB mark supports professionals by highlighting the quality of their products, services and skills.

It certifies the compliance of products with conditions set out in certification reference systems, which are established through the participation of all stakeholders. These conditions come from commonly accepted standards and include additional requirements that take into account the needs of users or add value to products.

As a certification body, the CSTB performs all certification operations, from the development of reference documents to the issuance of certificates and monitoring of certificate holders. It determines the terms of use for the QB mark, which are described in the "Certification Rules for the Mark".

Le CSTB définit les conditions dans lesquelles la marque QB est délivrée aux demandeurs, maintenue aux titulaires, suspendue ou retirée. Ces conditions sont décrites dans le référentiel de certification.
