RFspin Calibration Laboratory Is Now ISO/IEC 17025 Accredited

Our calibration laboratory has reached an important milestone. On October 6, 2026, the Czech Accreditation Institute (ČIA) granted accreditation No. 453/2026 to RFspin Calibration Laboratory (No. 2433) under ISO/IEC 17025:2018.

Antennas are not just something we calibrate, they are what we design and build. Alongside our existing services, our laboratory now puts that know-how to work on your antennas, whatever their make, and backs the results with a certificate recognized internationally.

What we calibrate

Our accreditation covers antennas of any make across the full 500 MHz to 40 GHz range, in one laboratory:

• Antenna gain: three-antenna method at 1 m (SAE ARP 958E) or 3 m (ANSI C63.5), uncertainty from 0.7 dB
• Antenna factor: same methods, uncertainty from 0.7 dB
• Reflection coefficient: vector network analyzer, uncertainty from 0.21 dB

What you get

• A certificate with the ČIA mark, recognized in all EA MLA and ILAC MRA signatory countries
• Your measured data in the formats you work with, online 24/7 in our Mini Antenna Portal
• No customs formalities when you ship from within the EU

Whether you run a test laboratory or test your products in-house, you can now build your results on accredited data. We look forward to calibrating your antennas.
