Overview

ISO 22915-8:2026 is a part of the ISO 22915 series, focusing on the verification of stability for industrial trucks under special operational conditions. Specifically, this part addresses an additional stability test for trucks operating when stacking with the mast tilted forward and the load elevated. Ensuring the stability of industrial trucks in this critical condition is essential for workplace safety in environments such as warehouses and manufacturing facilities.

This international standard is developed by ISO Technical Committee 110, Subcommittee SC 2 (Safety of powered industrial trucks). It applies to several classes of industrial trucks, as defined in ISO 5053-1, when equipped with a tiltable mast:

  • Counterbalance lift trucks
  • Reach and straddle trucks
  • Pallet-stacking trucks
  • Side-loading trucks
  • Multi-directional lift trucks
  • Rough-terrain trucks
  • Articulated counterbalance lift trucks

Key Topics

ISO 22915-8:2026 outlines requirements and procedures for an additional stability test, specifically for situations where the truck is:

  • Stacking loads
  • Operating with the mast fully tilted forward
  • Lifting with the load in an elevated position

Core elements include:

  • Test conditions aligning with ISO 22915-1 for consistent methodology
  • Clear instructions for positioning each truck type on a tilt table
  • Mast and fork requirements: both must be fully elevated and tilted forward during the test
  • Reference to related test procedures in other parts of ISO 22915 (Parts 2, 3, 4, 5, 7, 13, and 15)

By focusing on this special operating condition, the standard enhances safety protocols and reliability for trucks in demanding material handling scenarios.

Applications

ISO 22915-8:2026 is essential for:

  • Manufacturers of industrial trucks: To ensure new equipment meets international stability requirements for the full range of operational scenarios, including challenging stacking situations.
  • Testing and certification bodies: As a normative reference for product assessment and compliance certification.
  • Health and safety officers: To specify stability standards when evaluating industrial truck performance, reducing workplace risk, and supporting regulatory compliance.
  • Facilities managers in logistics, warehousing, manufacturing, and supply chain operations: To select trucks suitable for use in environments where mast tilt and elevated loads are common, thereby enhancing operational safety and efficiency.

Applying ISO 22915-8:2026 helps organizations minimize the risk of tipping and accidents during potentially hazardous stacking operations, protecting personnel and equipment.

  • ISO 22915-2, -3, -4, -5, -7, -13, -15: Individual parts for stability verification tests specific to different truck types
  • ISO 22915-10, -20: Additional tests for other special conditions (e.g., lateral or offset loads)

By integrating ISO 22915-8:2026 with related standards, organizations can establish a comprehensive stability and safety management system for all powered industrial trucks across a wide range of use cases.
