Описание (английский):

This document specifies the general requirements for the measurement and evaluation of human exposure to hand-transmitted shock vibrations. For the purposes of this document, hand-transmitted shock vibration is any impactive or impulsive vibration that the machine or tool produces as a sequence of single events (isolated shock vibrations) linked by periods of no, or lower vibration. This document specifies parameters for the evaluation of machinery emissions of hand-transmitted shocks in the frequency range covered by ISO 5349-1 (nominally the frequency range covered by the octave bands from 8 Hz to 1 000 Hz). NOTE It is recognised that shock vibration often includes substantial high-frequency vibration energy. Therefore, reporting of information on hand-transmitted shock at higher frequencies that those specified in this document can be valuable.

Abstract

Overview

ISO 5349-3:2025 - Mechanical vibration - Measurement and evaluation of human exposure to hand-transmitted vibration (HTV) - Part 3: focuses on isolated and repeated hand-transmitted shock (HTS) using the frequency range of ISO 5349-1 (nominally octave bands from 8 Hz to 1 000 Hz). The standard specifies general requirements, measurement procedures and metrics for evaluating shock-type vibrations produced by hand-held, hand-guided or hand-fed machinery. It complements ISO 5349-1 and ISO 5349-2 and references instrumentation requirements in ISO 8041-1.

Key topics and technical requirements

Scope and definitions: Defines isolated, repeated and continuous shock vibrations and related terms (e.g., shock, HTS, repetition rate).
Frequency range and weighting: Primary evaluation uses the frequency range covered by ISO 5349-1 with a flat frequency weighting component of the W weighting; the standard recognises that HTS often has higher-frequency content and recommends reporting higher-frequency data where useful.
Measurement parameters:
- Vibration Peak Magnitude (VPM) - a metric representing the mean of peak acceleration amplitudes for HTS events.
- Repetition rate (R) and mean repetition rate for periodically repeated shocks.
- Triaxial measurements and computation of instantaneous total acceleration values (x, y, z).
- Sampling, measurement period and transducer coupling - guidance on sensor location, orientation and data acquisition to ensure repeatability and comparability.
Instrumentation and uncertainty: Instruments conforming to ISO 8041-1 are recommended; references to uncertainty guidance (GUM) are included.
Reporting and test reports: Standard specifies required information for emission data, measurement conditions and parameters to support regulatory and research use.

Practical applications and users

ISO 5349-3:2025 is intended for:

Machine and tool manufacturers - to evaluate and reduce HTS emissions and to comply with emerging regulatory requirements (for example, EU machinery safety rules requiring mean peak acceleration reporting).
Occupational health and safety professionals - to assess worker exposure to shock vibration and to design control/mitigation measures.
Test laboratories and instrument manufacturers - to standardize measurement methods, sampling and reporting.
Researchers studying health effects of repeated and isolated shocks and developing exposure-response relationships.

Typical equipment covered: nail guns, road breakers, grinders, saws and other hand-held tools that produce percussive or impulsive vibration.
