ISO INTERNATIONAL STANDARD 5347-16 First edition 1993-12-15 Methods for the calibration of vibration and shock pick-ups Part 16: Testing of mounting torque sensitivity Methodes pour I'étalonnage de capteurs de vibrations et de chocs - Partie 16: Essai de sensibilite de couple de serrage ISO Reference number ISO 5347-16:1993(E) IS05347-16:1993(E) Foreword isO (the International Organization for Standardization) is a worldwide of preparing International Standards is normally carried out through IsO represented on that committee. International organizations, governmental and non-governmental, 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 voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote International Standard ISO 5347-16 was prepared by Technical Committee ISO/TC1o8,Mechanicalvibrationandshock,Sub-CommitteeSC3,Use and calibration of vibration and shock measuring instruments. ISO 5347 consists of the following parts, under the general title Methods for the calibration of vibration and shock pick-ups: -PartO:Basic concepts Part 1: Primary vibration calibration by laser interferometry -- Part 2: Primary shock calibration by light cutting Part 3: Secondary vibration calibration Part 4: Secondary shock calibration Part 5: Calibration by Earth's gravitation -.Part 6: Primary vibration calibration at low frequencies - Part 7: Primary calibration by centrifuge Part 8:Primary calibration by dual centrifuge ISO1993 All rights reserved.
