Overview

EN ISO 31915-3:2026 specifies general requirements for vibration measurement methods and reduction related to aircraft ground support equipment (GSE). This European and international standard, developed by CEN, focuses on whole body vibration as a significant hazard, providing unified procedures for measuring and evaluating vibration emitted to drivers-standing or seated-on self-powered, freely movable GSE during operation. It aims to support type evaluation, declaration, and verification of vibration emissions, contributing to the safety and ergonomic design of GSE used at airports.

This standard is intended for use alongside the EN 1915 and EN 12312 series, which cover additional general and specific requirements for GSE. EN ISO 31915-3:2026 applies only to equipment manufactured after its publication date and does not cover the assessment of daily vibration exposure for workers.

Key Topics

• Whole Body Vibration Hazards
  Focuses on identifying, measuring, and mitigating hazards arising from vibration transmitted to equipment operators.

• Measurement Methods
  Details systematic procedures for measuring root mean square (r.m.s.) acceleration of whole body vibration in both seated and standing operation modes, following internationally recognized frequency weighting and instrumentation standards.

• Test Track and Setup
  Defines standardized test track requirements, obstacle specifications, and measurement conditions to ensure consistency across testing environments.

• Vibration Reduction Measures
  Encourages manufacturers to incorporate design improvements such as pneumatic tyres, suspension seats, and vibration-isolated cabins to minimize vibration emissions.

• Reporting and Declaration
  Outlines the necessary elements for comprehensive test reporting and official vibration emission declaration in compliance with EN 12096:1997.

• Verification
  Specifies procedures for verifying declared vibration values, ensuring accountability and conformity with regulatory requirements.

Applications

EN ISO 31915-3:2026 plays a vital role in the following practical applications:

• GSE Type Certification
  Provides a harmonized reference for GSE manufacturers and testing laboratories to demonstrate compliance with essential EU and ISO requirements concerning vibration.

• Design and Procurement
  Supports design engineers, procurement specialists, and safety personnel in selecting GSE models that meet safety and ergonomic criteria for operator comfort.

• Regulatory Compliance
  Facilitates adherence to EU machinery regulations (including Regulation (EU) 2023/1230), improving market access and ensuring airport operators meet legal obligations for equipment safety.

• Maintenance and Operation
  Assists operators in setting acceptable vibration emission benchmarks and in identifying additional user-side or organizational risk minimization procedures.

• Comparative Assessment
  Enables objective comparison of vibration characteristics between different GSE designs, seats, or tyre configurations.

Related Standards

To ensure comprehensive compliance and safety, EN ISO 31915-3:2026 should be applied in conjunction with the following related standards:

• EN 1915 Series

  • Part 1: Basic safety requirements
  • Part 2: Stability and strength requirements
  • Part 4: Noise measurement methods and reduction

• EN 12312 Series
  (Various parts covering specific GSE categories such as passenger stairs, baggage tractors, deicers, etc.)

• EN 1032:2003+A1:2008
  Mechanical vibration-Testing of mobile machinery to determine vibration emission values

• EN 12096:1997
  Declaration and verification of vibration emission values

• EN ISO 12100:2010
  General principles for risk assessment and reduction

By following EN ISO 31915-3:2026, stakeholders in the aviation ground handling sector gain a standardized, reliable methodology for managing whole body vibration hazards-vital for operator safety, regulatory alignment, and operational excellence in airport environments.

Introduction
The aim of this document is to deal with vibration as a hazard and to provide methods for the measurement
and reduction of vibration emission transmitted to the whole body of drivers of GSE, when driving. For
determining whole body vibrations under stationary operating conditions and hand-arm vibrations
EN 1032:2003+A1:2008 is used.
It is intended that the results obtained can also be used to compare GSE of the same category or a given GSE
when equipped with different seats or tyres, etc.
Fitting different seats, changing the tyre specification, etc. can lead to different vibration values. Due to
the specific operation of GSE, however, EN 1032:2003+A1:2008 cannot be applied directly for whole body
vibration under driving conditions, and therefore, the preparation of this document for GSE has become
necessary.
This document cannot be used for field measurements to determine the daily exposure of the driver to
vibration.
This document is a Type C standard as stated in EN ISO 12100:2010.
The machinery concerned and the extent to which hazards, hazardous situations and events are covered are
indicated in the scope of this document.
When requirements of this type C standard are different from those which are stated in type-A or type-B
standards, the requirements of this type-C standard take precedence over the requirements of the other
standards, for machines that have been designed and built according to the requirements of this type-C
standard.
