ISO 8041-1-2017 pdf free download.Human response to vibration — Measuring instrumentation — Part 1:
General purpose vibration meters
Réponse des individus aux vibrations — Appareillage de mesure — Pm-tie 1: Instrument de mesure d usage général.
the instrument documentation may describe alternative methods to test the specified operations of the human-vibration meter.
NOTE The manufacturer of the human-vibration meter is free to provide an input test point, or a dummy vibration transducer of specified electrical impedance (termination), or an equivalent input adapter (electrical or non-electrical) to perform electrical tests on the instrument.
The instrument documentation shall specify the maximum peak vibration at the vibration transducer and the maximum peak-to-peak signal (e.g. charge or voltage) that can be applied at the electrical input facility. The maximum vibration value and the maximum peak-to-peak voltage shall not cause damage to the instrument.
The tolerance limits given in this document include the associated expanded uncertainties of nwasurement, calculated for a coverage factor of 2, corresponding to a coverage probability of approximately 95 %, in accordance with the guidance given in ISO/IEC Guide 98-3. Guidelines for estimating instrumental measurement uncertainty are provided in Annex 1.
5.2 Display of signal magnitude
For instruments that can display more than one measurenwnt quantity, a means shall be provided Lu ascertain clearly the measurement quantity that is being displayed, preferably indicated by standard abbreviations or letter symbols.
The quantities that can be displayed by the human-vibration meter shall be described in the instrument documentation, along with a description of the corresponding indications on each display device.
The instrument shall display the frequency-weighted acceleration values. Optionally, it may also display the frequency-weighted acceleration value multiplied by a factor k, as defined in ISO 2631-1. Where multiplying factors are used, this shall be clearly indicated on the instrument and the instrument shall be capable of displaying the multiplying factors.
Where a combined axis output Is displayed (e.g. vibration total value, iLLZ), the instrument shall be capable of displaying the values of the multiplying factors used.
When results of a measurement are provided at a digital output, the instrument documentation shall describe the method for transferring or downloading the digital data to an external data storage or display device. The instrument documentation shall identify the computer software as well as the hardware for the interface. Internationally standardized interface bus compatibility is recommended.
Each alternative device for displaying the signal value, stated in the instrument documentation as conforming to the specifications of this document, is considered an integral part of the instrument.ISO 8041-1-2017 pdf free download.
