Thanks to its test facilities and expertise in the engineering of tests, the CSTB is able to conduct its research, assessment and certification activities at the highest level. Test engineering – a multiphysical approach to buildings and customized protocols – directly measures the performance characteristics of an innovation for which a testing framework has yet to be standardized. When appropriate, the CSTB can also use a combined approach with digital simulation to push the analysis further.

The CSTB can also conduct full-scale tests to explore the integration of products in buildings as closely as possible to actual conditions. It checks the effectiveness of innovations, factoring in how they will be used, their industrial characteristics and the degree of complexity of the physical phenomena involved.

The CSTB has more than 1,200 test benches as well as major test facilities used by the different scientific and technical disciplines. These facilities have a broad range of capabilities for testing materials, products and structural components, for traditional and innovative processes.

The testing activities are accredited by the French national accreditation body (COFRAC). The accreditation numbers are: 1-0300, 1-0301, 1-0302, 1-0304, 1-0305, 1-0306, 1-2122 and 1-1542 for tests, and 2-1930 for calibration (scopes of accreditation are available at www.cofrac.fr).
