Mechanical vibration - Measurement and evaluation of human exposure to hand-transmitted vibration - Part 3: Isolated and repeated shocks using the frequency range of ISO 5349-1 (ISO/DIS 5349-3:2024)
This document gives information and guidance on the evaluation and assessment of hand-transmitted shock. For the purposes of this document, isolated shock is any impactive or impulsive vibration that the machine or tool user experiences as a sequence of individual events (single shocks) linked by periods of no, or low vibration.
This document provides guidance on the identification, measurement, evaluation and possible health effects of hand-transmitted shock vibrations containing vibration energy up to the frequency range covered by ISO 5349-1 (approximately 6,3 Hz to 1 250 Hz).
Note: It is recognised that shock vibration often includes substantial levels of high-frequency vibration energy. The measured peak values of HTS are likely to be higher if the upper frequency limit is increased. High-frequency shocks, composed of vibrations at frequencies greater than 1 250 Hz, are dealt with in Draft ISO/DTS 5349-4.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The 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-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.
The procedures used to develop this document and those intended for its further maintenance are described
in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types
of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the
ISO/IEC Directives, Part 2 (see www.iso.org/directives).

Introduction
The risk estimation for hand-arm vibration injury is based on ISO 5349-1. The scope of the 2001 revision
of that ISO Standard notes that “the time dependency for human response to repeated shocks is not fully
known” and the application of ISO 5349-1 to such vibration is to be “made with caution”.
Despite the lack of knowledge in this field, it is desirable to standardise methods for evaluating hand-
transmitted shock (HTS) vibrations from hand-held and hand-guided machinery, and specifically provide a
metric suitable for evaluating the peak amplitude of acceleration signals. This document gives guidance for
evaluating HTS in the frequency range covered by ISO 5349-1.
NOTE European Regulations relating to machinery safety require (from 2027) manufacturers or suppliers to
provide values for the “mean of the peak amplitude of the acceleration” from repeated HTS.
The objective for this document is to:
— enhance research on health effects from HTS;
— provide machine manufactures and user a method for evaluating hand-transmitted shock;
— encourage and enable:
— machine producers to reduce hand-transmitted shock;
— the development of mitigation measures on existing tools;
— the reduction of hand-transmitted isolated and repeated shock vibration exposures in the workplace.
The use of this document will contribute to the gathering of consistent HTS data to improve occupational
safety. There is currently no clear evidence that HTS produces specific health effects beyond those associated
with hand-transmitted vibration or presents a risk of developing other musculoskeletal injuries to the hand
and arm such as repetitive strain injury and carpel tunnel syndrome. The systematic measurement and
reporting of parameters relating to HTS may provide evidence of associations with individual health effects.
This document specifies the general requirements for the measurement and evaluation of human exposure
to HTS. It builds on the requirements of ISO 5349-1 and measurement guidance in ISO 5349-2. It uses
instrumentation that conforms to the requirements of ISO 8041-1. The current version ISO 8041-1:2017 does
not require measurement of the peak value of acceleration for hand-transmitted vibration, however, the
instrumentation conforming to ISO 8041-1:20
