CSTB Certificate: What It Is and How to Obtain One

What Is a CSTB Certificate?

A CSTB (Centre Scientifique et Technique du Bâtiment) certificate confirms that a construction-sector product meets defined quality, safety, and environmental standards. It is applicable to construction materials, building products, and other goods used in the construction industry. The certificate provides evidence that the product has been tested, assessed, and accepted as fit for the declared application, and it gives specifiers and buyers a reliable record that the product complies with the referenced standards.

How to Obtain a CSTB Certificate

The CSTB process follows a defined sequence:

• Application: Sistem Patent Kalite files the CSTB application on your behalf. The application identifies the product, its intended use, and the standards it needs to be assessed against.
• Product evaluation: CSTB reviews the product in detail. The review covers material composition, declared performance, and compliance with the applicable product standards and environmental requirements.
• Audits and testing: CSTB arranges laboratory testing and any required on-site audits or factory-production-control checks.
• Certification and issuance: if the product meets the requirements, the CSTB certificate is issued, confirming that the product has been verified as conforming to the referenced standards.

Which Products Fall Under CSTB?

CSTB scope covers a wide set of construction-sector categories, from structural materials through to facade components, insulation, thermal products, windows, doors, and interior finishes. If you are unsure whether your product is within scope, a pre-application review will confirm the applicable standards and the CSTB procedure that fits.

CSTB Certificate Fees

Fees depend on the product category, the testing programme, and the number of variants within scope. Ask for a quote once the scope is confirmed.
