UKAS accreditation no. 0138

Our Irlam Laboratory in the UK is accredited by the United Kingdom Accreditation Service (UKAS) in accordance with DIN EN ISO / IEC 17025 for the measurement parameters pressure and mass. The laboratory has been accredited by ukas (formerly BCS or NAMAS) since 1984 since which we have gradually extended and improved our calibration facilities to cover the ranges shown below.

Calibration laboratory for Pressure

In our calibration laboratory for pressure we calibrate measuring instruments in the measuring range from 10 mbar absolute  … +5,000 bar gauge with uncertainties of 0.004 % … 0.01 % of reading, depending on the pressure range. For the calibration, in our calibration laboratory, we only ever use high-accuracy references such as dead-weight testers, digital piston gauges and pressure controllers.

For dead-weight testers we offer two types of calibration – ‘pressure equivalent calibration’ where we compare the pressure generated by a dead-weight tester against a reference standard at a number of points over the range or ‘area calibration’ where we determine the effective area of the piston-cylinder unit over the range of the instrument (this is usually accompanied with a mass calibration of the weight set done in our mass laboratory).

Calibration laboratory for Mass

In our calibration laboratory for mass we can weigh dead-weight tester masses from 0.1g to 20kg with uncertainties of 0.5mg, 15mg and 0.0003 % of reading, depending on the mass range. For the calibration, in our calibration laboratory, we only ever use high-accuracy electronic mass comparators and reference weights to F1 standard.

Calibration of other parameters

Through our DKD accredited laboratory in WIKA Germany, we can also provide temperature and electrical calibration. Alternatively we can offer ukas calibration on these parameters through a third party calibration laboratory.
