Our metrology and calibration services

Metrology and calibration - Accelerometric metrology

These services concern the fields of electromagnetic compatibility and mechanical and climatic environments.

Our Emitech and Environne'Tech metrology and calibration services have been developed at the same time as our testing laboratories. They have been created to meet our internal needs and contribute to the Cofrac accreditations of our laboratories.

Furthermore, our Emitech metrology laboratory has itself been awarded Cofrac Calibration accreditation.

Developed on the basis of expertise acquired within our group, Emitech’s metrology and calibration services are made available externally to manufacturers equipped with their own laboratories and sharing the same stringent requirements as our own laboratories.

Cofrac-accredited calibrations of equipment specifically used for EMC testing:

ESD generators pursuant to the EN61000-4-2 and ISO10605 standards
attenuators
loads
preamplifiers
tests leads
LISN pursuant to the following standards: CISPR16-1-2, CISPR25, ISO7637-2, DO-160, MIL-STD461, etc.
CDN pursuant to EN61000-4-6 standard

While our accreditation guarantees a recognised level of quality, we also perform calibrations outside the scope of the accreditation:

antennas (biconical, BicoLog periodic, log-periodic, horn, log-spiral, dipole, whip): Measurement of antenna factor (pursuant to ANSI C63.5 or SAE-ARP958) and VSWR
loop antennas or magnetic field loops: Measurement of antenna factor or conversion factor
electric or magnetic field probes: Measurement of correction factor
connection terminals: Measurement of transfer impedance
couplers
amplifiers
synthesised generators
EMC receivers and spectrum analysers
milliwattmeters
fast transient generators, coupling networks, capacitive clamps (pursuant to EN61000-4-4)
shock wave generators, coupling networks (pursuant to EN61000-4-5)

We can carry out certain services directly on our clients’ premises:

Validation of test sites (sites in open environments, semi-anechoic cages or FAR rooms): NSA, VSWR (according to CISPR16-1-4, ANSI C63.4, ETSI TR 102-273-2/3/4)
Verification of Faraday cage performance: field uniformity (EN 61000-4-3), shielding efficiency (EN 50147-1, IEEE, etc.)

As we fully understand laboratories’ needs, we offer quick turnarounds to minimise your downtime.

Calibration:

accelerometers and their conditioners
force sensors
pressure sensors
temperature sensors

As we fully understand laboratories’ needs, we offer quick turnarounds to minimise your downtime accompanied by highly accurate automated traceability of the accuracy of measuring instruments to minimise the uncertainty of measurements.
