Th
11、e work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-gov
12、ernmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Draft International Standards adopted by the technical committees are circulated to the member bodies for
13、voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. International Standard ISO 5347-22 was prepared by Technical Committee ISO/TC 108, Mechanical vibration and shock, Subcommittee SC 3, Use and calibration of vibration and shock me
14、asuring instruments. ISO 5347 consists of the following parts, under the general title Methods for the calibration of vibration and shock pick-ups: Part 0: Basic concepts; Part 1: Primary vibration calibration by laser interferometry; Part 2: Primary shock calibration by light cutting; Part 3: Secon
15、dary vibration calibration; Part 4: Secondary shock calibration; Part 5: Calibration by Earths gravitation; Part 6: Primary vibration calibration at low frequencies; Part 7: Primary calibration by centrifuge; Part 8: Primary calibration by dual centrifuge; Part 9: Secondary vibration calibration by

This part of ISO 5347 lays down detailed specifications for the instrumentation and p
20、rocedures to be used for accelerometer resonance testing. It applies to rectilinear accelerometers of the piezoresistive, piezoelectric and variable capacitance types in the frequency range 50 Hz to 200 kHz. The procedures are in general contrary to those described in ISO 5347-14 which is limited to
21、 undamped accelerometers. The frequency response of a piezoelectric accelerometer depends on the value of the (lowest) resonance frequency of the instrument when mounted on the structure to be tested. It does not appear possible to specify a test which will determine this frequency for all installat
22、ions of a given accelerometer. This procedure gives the accelerometer resonance frequency under a set of standard reproducible conditions, with the understanding that the resonance frequency in actual use will in all probability be appreciably different (generally lower, by a factor depending on the
23、 mass and compliance of the test structure and the method of attachment). The procedure is not suitable for evaluating the mounted resonance frequency for a field of application; a suitable method is given in ISO 5348. 2 Normative reference The following standard contains provisions which, through r
24、eference in this text, constitute provisions of this part of ISO 5347. At the time of publication, the edition indicated was valid. All standards are subject to revision, and parties to agreements based on this part of ISO 5347 are encouraged to investigate the possibility of applying the most recen
