In 2017, SIEPEL got ISO/IEC 17025: 2005 accreditation (scope 1-6220 available on, covering the following measurements in shielded rooms and anechoic chambers areas:

  • Shielding effectiveness (from 10 kHz to 40 GHz) in accordance with EN 50147-1 standard
  • Quiet zone (from 30MHz to 1 GHz, and from 1 GHz to 18 GHz) in accordance with CISPR 16-1-4 standard
  • Uniform field area (from 26 MHz to 18 GHz) in accordance with CEI/EN 61000-4-3 standard.


These measurements can be performed on all kind of anechoic chambers and shielded rooms, no matter the brand. Prior to measurements, we carry out test plans. Once the measurements are done, we establish independent reports according to the criteria defined by COFRAC (French accreditation body).
