Full title and description

St ISO 15794-2001 — International Standard ISO 15794:2001, "Bi-directional and multi-directional fork-lift trucks — Stability tests". This standard specifies basic laboratory and field tests to verify the stability characteristics of bi-directional and multi-directional fork-lift trucks (including those with tiltable or non-tiltable masts or fork arms) and applies to trucks fitted with fork arms and/or attachments.

Abstract

ISO 15794:2001 defines stability test procedures for bi-directional and multi-directional industrial lift trucks to assess overturning and load-handling stability under specified conditions. It excludes trucks that handle suspended loads which can swing freely and is intended to provide repeatable tests for manufacturers, testing bodies and regulators.

General information

• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 53.060 (Industrial trucks).
• Edition / version: Edition 1 (2001).
• Number of pages: 16 (official ISO listing; note that some national adoptions/copies list different page counts).

Scope

The standard specifies basic tests to verify the stability of bi-directional and multi-directional fork-lift trucks whether fitted with tiltable or non-tiltable masts or fork arms. It covers trucks fitted with fork arms and/or attachments and describes test set-ups, load conditions and acceptance considerations. ISO 15794:2001 explicitly excludes trucks that handle suspended loads that can swing freely.

Key topics and requirements

• Definitions and classification of bi-directional and multi-directional fork-lift trucks.
• Test rig and instrumentation requirements for stability measurement (incl. static and dynamic test arrangements).
• Load conditions and positioning for repeatable stability checks, including use of attachments and fork arms.
• Procedures to determine tipping thresholds and safe working conditions under specified configurations.
• Exclusions and limitations — in particular, not applicable to freely suspended, swinging loads.
• Reporting requirements for test results to support conformity assessment and design verification.

Typical use and users

Used by forklift manufacturers, product safety and compliance engineers, independent testing laboratories and certification bodies to assess and document stability performance during design validation and type testing. Also referenced by procurement specialists, fleet safety managers and standards committees when defining or harmonizing stability test procedures for multi-directional and bi-directional trucks.

Related standards

Relevant and related documents include other ISO standards on industrial-truck stability and safety (for example ISO 13563 series on single-side loading trucks and additional stability tests) and the wider ISO/TC 110 suite (including parts of the ISO 3691 family addressing industrial truck safety). National adoptions and identical publications exist (e.g., BS ISO 15794:2001, SS‑ISO 15794).

FAQ

Q: What is this standard?

A: ISO 15794:2001 is an International Standard that defined stability test methods for bi-directional and multi-directional fork-lift trucks.

Q: What does it cover?

A: It covers basic stability tests (static and dynamic test arrangements), load and attachment conditions, and reporting for trucks with tiltable or non-tiltable masts/fork arms; it excludes trucks handling freely swinging suspended loads.

Q: Who typically uses it?

A: Manufacturers, test laboratories, certification bodies, safety engineers, fleet managers and standards committees concerned with industrial truck stability and safety.

Q: Is it current or superseded?

A: ISO 15794:2001 has been withdrawn (the ISO record shows the standard as withdrawn; national catalogues show withdrawal actions around November 2013). Users should refer to current ISO/TC 110 publications (including newer parts of the ISO 3691 series and related documents) for up-to-date safety and test requirements.

Q: Is it part of a series?

A: It is part of the body of ISO work under ISO/TC 110 on industrial trucks; related standards address other loading configurations and additional stability tests (for example the ISO 13563 series and the ISO 3691 family).

Q: What are the key keywords?

A: Bi-directional, multi-directional, fork-lift truck, stability test, overturning, industrial truck safety, ISO 15794.
