Overview
ISO 22915-5:2020 - Industrial trucks - Verification of stability - Part 5: Single-side-loading trucks specifies standardized test procedures to verify the stability of single-side-loading trucks (with tiltable or non-tiltable masts or fork arms). The standard applies to trucks fitted with fork arms and/or attachments and defines how to set up test conditions, position the truck and load datum, perform stability tests, and mark capacity information for operator reference. ISO 22915-5:2020 is part of the ISO 22915 series and updates the 2014 edition (minor revision; Clause 2 updated to reference ISO 5053-1).
Key topics and technical requirements
- Scope and applicability: Covers single-side-loading trucks with fork arms and attachments, both tiltable and non-tiltable masts.
- Test conditions: References ISO 22915-1 for general test rules and details specific positioning on a tilt table (alignment of the truck relative to the tilt axis and articulating steer axle).
- Load datum point (E/F): Defines how to identify the load datum point on the fork or fork carrier and how to transfer that datum to the tilt table for repeatable testing, including adjustments for mast elevation and tiltable masts.
- Verification matrix (Table 1): Specifies required tests covering lateral, travelling and stacking conditions; variations include load at/without centre, lift height, load-carrier position (retracted, extended, vertical), mast positions, and use/engagement of stabilizers or axle locks.
- Marking: Requires that capacity under operating conditions (with stabilizers/axle locks engaged and disengaged where relevant) be displayed on an information plate visible to the operator in the normal operating position, per ISO 3691-1.
- Normative references: ISO 3691-1 (safety requirements), ISO 22915-1 (general stability verification), ISO 5053-1 (vocabulary/types).
Applications and who uses this standard
ISO 22915-5:2020 is used by:
- OEMs and design engineers to validate stability during product development and certification.
- Test laboratories and conformity assessment bodies performing standardized stability tests.
- Safety and compliance managers ensuring equipment meets ISO and regulatory requirements.
- Fleet managers and procurement teams specifying trucks for lateral loading operations.
- Regulators and inspectors assessing workplace safety where single-side-loading trucks are used.
Benefits include consistent, repeatable stability measurement, improved operator safety, and clear capacity marking for on-site use.
