- Abstract:
- The traceability to the acceleration measurements for the industry is done in France by the LNE. This traceability to the national standards is necessary for the industries that have processes where knowledge of the parameters related to the acceleration is essential in terms of quality and safety, such as nuclear, space, automotive or military fields.
The reference accelerometers calibrations for the industry and other laboratories are performed at the LNE's site located in Trappes since 2006 by the absolute method using a Michelson interferometer. However, the equipment used, presented in [1], was of old design and a first step of the upgrade is presented in [2].
This article presents the end of the qualification, including the comparison of methods 1&2 versus method 3 described in standards 16063-1 and -11 [3]. It presents the comparison results of two different design exciters: one in beryllium also an air bearing guide and one with a pierced aluminum moving element with a mechanical guide.
Metrological approval was based on the consistency achieved between the calibration results for given accelerometers obtained using the new bench and those obtained using the original bench.
A comparison with a national primary vibration calibration laboratory was performed and presented. - Keywords:
