Following an extensive qualification programme, Torquemeters Ltd calibration laboratory in Ravensthorpe has been granted UKAS accreditation against the requirements of ISO/IEC 17025:2017 – General requirements for the competence of testing and calibration laboratories.
This accreditation is based on Torquemeters Ltd ability to conduct torque and phase calibrations to a high degree of accuracy for incorporation into precision torque measurement devices.
Torquemeters use a qualified purpose-built torque calibration rig to conduct torque calibrations to BS7882:2017 or DIN51309:2005, designed to give the best certification capability and the lowest uncertainty of measurement. Balanced arms are supported by low friction bearings with the torque transmitted via flexible couplings to prevent end loads and moments being applied to the article under calibration. The reaction arm can be levelled to ensure the load arm is always horizontal and calibrated masses are used to give minimum uncertainty for all load conditions. The environment is controlled, and calibrations are conducted by qualified technicians to ensure quality and consistency of calibration and service. The calibration rig torque capability range is 300-3500 N∙m with uncertainty in applied torque better than 0.01% (k=2 for a probability of 95%).
Torquemeters’ accredited laboratory can also undertake calibration of phase meters. Units under test are assessed against calibrated waveform generators, reporting deviations at a range of phases and frequencies. Accredited ranges include phase angle or % phase measurement for amplitudes of 50mV rms and 500mV rms at frequencies up to 100kHz.
Over the past 70 years, Torquemeters has been responsible for the innovation of the first phase-shift torquemeters, now widely used both for testing & development within the aerospace industry. With this significant investment in the new calibration equipment and the successful conclusion of the year-long qualification programme, Managing Director, Ben Van Millingen, commented “We’re very pleased to have met the stringent requirements for UKAS accreditation, which has been a long-term ambition for the business, and underpins our commitment to supporting our customers’ needs for highly accurate torque measurement within their development testing programmes.”
The United Kingdom Accreditation Service (UKAS) is the sole National Accreditation Body for the United Kingdom. UKAS is recognised by government, to assess against internationally agreed standards, organisations that provide certification, testing, inspection and calibration services. UKAS accreditation demonstrates the competence, impartiality and performance capability of these evaluators. UKAS accredited certification, testing, inspection and calibration reduces the need for suppliers to be assessed by each of their customers. UKAS’ involvement in international groups such as EA, IAF and ILAC, provides for mutual recognition.
