Sediver Testing Facilities
Material science laboratory
Investigate materials and their behavior in service: vital to ensure a high level of performance and reliability of insulators over time.
Ageing test laboratory
Conduct endurance tests: essential to guarantee a high level of performance and reliability of insulators with long-term behavior under extreme service conditions.
Mechanical laboratory
Paramount to evaluate the mechanical ability of insulators to sustain extreme loads on insulators units and on complete configuration, including string hardware evaluation.
High Voltage laboratory
Carry out electrical tests: fundamental to achieve optimum insulation for each specific environmental condition, to qualify products and to assess the performance of any type of insulator string
Pollution laboratory
Perform pollution tests: critical to define the most suitable insulator design for each specific environmental condition and the performance of insulator strings under pollution.
Sediver Research Center laboratories obtained certification and accreditation recognized by more than 70 organisms in over 50 countries around the world.
The C.E.B High Voltage test laboratory fulfils the requirements of the standard NF EN ISO/IEC 17025 : 2017 - Cofrac accreditation testing, n° 1-0557 scope available on www.cofrac.fr.
This accreditation (issued by a third party) demonstrates the technical competence and the impartiality of our laboratory to carry out product conformity assessments.
The COFRAC organization ensures this through audits of our equipment and our test methods before issuing a new accreditation certificate.
This accreditation allows the research center to benefit from international recognition of the results obtained during its controls, COFRAC being a signatory of multilateral international agreements and being recognized worldwide in more than 50 countries (ILAC - International Laboratory Accreditation and IAF - International Accreditation Forum - through EA (European cooperation for Accreditation).
