Test Facilities

Reims laboratory approved “UL Client Test Data Program” Since July 2025, the Reims laboratory has been a “UL Client Test Data Program” participant, which attests to the site's ability to produce test data that can be used in UL (Underwriters Laboratories) conformity assessment processes, in accordance with the requirements of UL 1449, 5th edition and CSA-C22.2 No. 269, and in compliance with good quality practices as described in ISO/IEC 17025. This recognition reinforces CITEL's position as a reference player capable of designing, validating, manufacturing and now certifying its solutions under UL delegation.
International Standards
The phenomena were first characterized and a series of standardized waves created (1.2/50µs voltage wave and 8/20µs and 10/350µs current waveforms), then a number of standards defining surge arrester performance were issued, among them : Surge Protectors for Low-Voltage installations: - NF EN 61643-11 (France) - VDE 0675-6-11 (Germany) - EN 61643-11 (Europe) - UL1449 (USA) - IEC 61643-11 (International) Surge Protectors for Telecom equipment: - IEC 61643-21 (International) - ITU-T recommendations K11, K12, K17, K20, K21, K36 (International) - UL 497 A/B (USA)
