本文件中描述的新特性旨在提高宽带/瞬态输入(如冲击)校准和测量应用的质量。它提供了表征振动传感器对瞬态输入响应的方法,因此,通过从获取的输出信号预测输入,为瞬态振动信号的准确测量提供了基础。上述应用领域中使用的加速计的校准数据还应按照下述方法进行评估和记录,以提供超出ISO 16063-13和ISO 16063-22给出的单值特性所规定限值的测量能力和不确定度。
ISO 16063-43:2015 prescribes terms and methods on the estimation of parameters used in mathematical models describing the input/output characteristics of vibration transducers, together with the respective parameter uncertainties. The described methods estimate the parameters on the basis of calibration data collected with standard calibration procedures in accordance with ISO 16063?11, ISO 16063?13, ISO 16063?21 and ISO 16063?22. The specification is provided as an extension of the existing procedures and definitions in those International Standards. The uncertainty estimation described conforms to the methods established by ISO/IEC Guide 98?3 and ISO/IEC Guide 98?3:2008/Supplement 1: 2008.
The new characterization described in this document is intended to improve the quality of calibrations and measurement applications with broadband/transient input, like shock. It provides the means of a characterization of the vibration transducer's response to a transient input and, therefore, provides a basis for the accurate measurement of transient vibrational signals with the prediction of an input from an acquired output signal. The calibration data for accelerometers used in the aforementioned field of applications should additionally be evaluated and documented in accordance with the methods described below, in order to provide measurement capabilities and uncertainties beyond the limits drawn by the single value characterization given by ISO 16063?13 and ISO 16063?22.
