meet the expectations of regional, national or international companies
Always mindful of the quality of our analyzes and the reliability of our scientific data, the CNEP has numerous accreditations or certifications recognized worldwide.
Certification ISO 9001 - version 2015
Accreditation RENAULT ME D153200A
Centre de Ressources technologiques
Member of the Allizé-Plasturgie network
Coming from a fundamental research laboratory, the CNEP has been supporting Businesses (Large Groups, ETIs and SMEs), Research Organizations and Innovation Systems for more than 36 years.
The numerous industrial uses brought about by a better knowledge of the aging mechanisms of polymeric materials made it necessary to set up the CNEP (National Center for the Evaluation of Photoprotection) in 1986 to examine the original problems associated with the long-term quality control of polymer materials in use formulation.
After an exchange between the project manager and a CNEP manager, a study is proposed taking into account the expectations of the project and the samples available for the study. After agreement, a quote and a time limit for completing the study are proposed
The samples received at the CNEP are referenced in our Quality system and then shaped by us in order to meet the expectations of the project and the requirements of our accelerated aging equipment.
In the specific case of a durability study, the chemical and color changes during exposure in a SEPAP accelerated photo-aging chamber are monitored by IRTF under different adapted modes and by UV-Visible in order to have a global view of the mechanisms involved
At the end of the planned duration of exposure, a report bringing together all the analyzes and changes in the materials as well as a report allowing an estimate of the lifespan of the various materials is sent to the project manager who can ask advice from the researcher who wrote the report
The CNEP will be in very reduced activity from August 10 to 15, 2020, contact us preferably after this period.
