It is also intended to help create a mutual understanding of the criteria for successful hydro unit condition monitoring and to foster coopera...view more

This document specifies a laboratory method for measuring hand-transmitted vibration emission at the handles of hand-held power-driven angle and vertical grinders. It is a type-test procedure for establishing the magnitude of vibration in the gripping areas of a machine fitted with a specified test wheel and run under no‑load conditions. The method has been established for surface grinding tasks only. Cutting and sanding generally create lower vibrations. It is intended that the results be used ...view more

This document details specifications for the instrumentation and methods to be used for testing fixed temperature sensitivity of vibration transducers. It applies to rectilinear velocity and acceleration transducers. The methods specified use both a comparison to a reference transducer and an absolute measurement by laser interferometer. This document is applicable for a frequency range from 10 Hz to 3 kHz (method-dependent), a dynamic range from 1 m/s2 to 100 m/s2 (frequency-dependent) and a te...view more

This document specifies procedures for measuring mechanical mobility and other frequency-response functions of structures excited by means of an impulsive force generated by an exciter which is not attached to the structure under test. It is applicable to the measurement of mobility, accelerance or dynamic compliance, either as a driving point measurement or as a transfer measurement, using impact excitation. Other excitation methods, such as step relaxation and transient random, lead to signal-...view more

This document specifies requirements and guidelines for the analysis of lubricating oils, hydraulic fluids, synthetic fluids and greases. Tests for electrical insulating oils and heat transfer oil are outside the scope of this document.

This document establishes requirements to ensure appropriate exchange of information between manufacturers and users of auxiliary tables with a view to working out related specifications and possibly to comparing, in an objective way, the characteristics supplied by the manufacturers of auxiliary tables and associated guidance systems. This document is applicable to auxiliary tables which include slip tables and head expanders. It does not cover auxiliary tables with several degrees of freedom. ...view more

This document demonstrates the adequacy of specimens to resist dynamic loads without unacceptable degradation of its functional and/or structural integrity when subjected to the specified vibration test requirements as defined by a time history (long time history replication). These can either be recorded in measurement exercises or generated artificially. In both cases, this method allows for generating a test tailored to very specific applications. Typical applications are tests in which very ...view more

This document provides guidance to select a vibration generator that will be used to evaluate frequency responses of a test structure or to study how vibration grows/decreases along the structure. These structural dynamics tests can be carried out under field or laboratory conditions (see the ISO 7626 or ISO 10846[4][5][6][7] series). This document describes the selection procedure in terms of the force developed by a single vibration generator. Meanwhile, to move massive structures such as dams...view more

This document provides specific guidance on the interpretation of infrared thermograms as part of a programme for condition monitoring and diagnostics of machine systems. In addition, IR applications pertaining to machinery performance are addressed. This document is intended to: — provide guidance on establishing severity assessment criteria for anomalies identified by IRT; — outline methods and requirements for carrying out thermography of machine systems, including safety recommendations; — p...view more

The assessment of human exposure to vibration, to both the hand-arm system and the whole body, at the workplace relies on the combined evaluation of both vibration magnitudes and exposure times. Determining these values can employ various instrumentation types and data sources. ISO/TR 19664:2017 provides guidance and explanation of concepts used for the following:
- measurement processes;
- instrumentation types;
- vibration magnitude source.

This document specifies the instrumentation and procedure to be used for performing calibration of field vibration calibrators (FVCs). It is not applicable to FVCs used for the calibration of transducers. These are covered by ISO 16063‑21. Procedures and requirements of in situ calibration by FVC are beyond the scope of this document. Annex B provides more information on the application of FVC.
