Overview
ISO 31915-3:2026, Aircraft ground support equipment - General requirements - Part 3: Vibration measurement methods and reduction establishes internationally recognized procedures for measuring and reducing whole body vibration (WBV) emissions from self-powered ground support equipment (GSE) used at airports. This standard is aimed at mitigating WBV hazards for drivers standing or seated on freely moveable GSE during operation. It details standardized testing, evaluation, and declaration methods for vibration emissions, supporting the advancement of safety and comfort in airport ground operations. The standard is relevant for equipment manufacturers, fleet operators, regulatory bodies, and safety professionals seeking to ensure compliance and best practice in vibration risk management.
Key Topics
- Whole Body Vibration as a Hazard: Addresses WBV as a significant risk for GSE operators, highlighting the health implications of vibration exposure.
- Standardized Measurement Methods: Specifies procedures for measuring vibration transmitted to drivers-whether standing (on footplates) or seated (on seat pans)-following defined parameters such as test track setup, measurement location, and environmental conditions.
- Vibration Reduction Strategies: Outlines design and technical approaches for minimizing vibration, including the use of pneumatic tyres, suspension systems, vibration-isolated cabins, and seat suspension enhancements.
- Valid Test Procedures: Defines requirements for valid test runs, measurement instrumentation, and accuracy of speed and vibration data, ensuring reliable results for type evaluation.
- Verification and Declaration: Provides guidance for verifying and reporting vibration emission values, including how to document and declare results in compliance with related standards like EN 12096.
Applications
ISO 31915-3:2026 is specifically applicable to self-powered, moveable GSE (such as tugs, belt loaders, and container loaders) employed in civil airport ground operations. Practical applications include:
- Type Evaluation of Equipment: Manufacturers and purchasers use the standard’s procedures for comparative type testing, determining whether GSE models meet vibration emission criteria.
- Regulatory Compliance: Serves as a reference for regulatory bodies and airport authorities to enforce health and safety requirements concerning operator exposure to vehicle-induced vibration.
- Product Development and Design: Engineers apply the standard’s vibration reduction recommendations to improve GSE comfort and operator safety.
- Procurement and Safety Audits: Airport operators can standardize evaluation, procurement, and ongoing safety assessments of their GSE fleets based on ISO 31915-3 test results and declarations.
- User Information: Ensures comprehensive documentation and communication of vibration emission data and reduction methods in user manuals and technical materials.
Notable Limitations
- Not for Personal Exposure Assessment: The standard is not intended for field measurement of daily vibration exposure for individual operators.
- Applies only to Post-Publication GSE: Covers equipment manufactured after the standard’s publication date.
Related Standards
To ensure consistency and comprehensive coverage, ISO 31915-3:2026 is designed for use alongside several key standards:
- EN 1915 series - General safety requirements for aircraft ground support equipment
- EN 12312 series - Specific requirements for various types of GSE
- 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
- ISO 12100:2010 - Safety of machinery, general principles for risk assessment and risk reduction
Adherence to ISO 31915-3:2026 supports harmonization across international GSE safety practices, ensuring safer airport working environments and improved GSE product reliability.
