ISO 20474-13:2017

Overview

ISO 20474-13:2017 - "Earth-moving machinery - Safety - Part 13: Requirements for rollers" specifies safety requirements that are specific to rollers (as defined in ISO 6165). It is a type‑C standard intended to be used together with ISO 20474‑1 (the general safety requirements for earth‑moving machinery). The specific requirements in ISO 20474‑13:2017 take precedence over the general requirements where they differ. The standard addresses hazards during commissioning, operation and maintenance and is not applicable to machines manufactured before its publication.

Key topics and technical requirements

ISO 20474-13:2017 focuses on the particular safety needs of rollers (single‑drum, tandem, combined, pneumatic tyre, etc.). Major technical topics and indicated requirements include:

• Scope and definitions - Roller classifications and operator modes (ride‑on, non‑riding, remote‑control) per ISO 6165.
• Operator stations (ride‑on machines) - Minimum internal clearances when the operator is offset (seat centreline to enclosure ≥ 295 mm); provisions for cabs and limits on doors/windows latched open.
• Non‑riding machines and handle bars - Vertical swing range of single‑drum non‑riding steering handle: 0.2 m to 1.4 m above ground.
• Protection against crushing - Non‑riding and remote‑control machines require a stopping device to prevent trapping; stopping device must stop the machine within its operating range and have an effective operating force ≤ 230 N.
• Controls, braking and emergency stop - Requirements for travel controls, brakes and emergency stop functions consistent with referenced standards (e.g., ISO 13850).
• Access and maintenance - Safe access systems, guard rails and maintenance point considerations.
• Noise and vibration - Mandatory information and test codes; normative annexes include a noise test code and hand–arm vibration test code for non‑riding and remote‑control vibratory rollers with working width ≤ 1 m.
• Information for use - Marking, operator manuals and warning devices.

Practical applications

ISO 20474-13:2017 is used to:

• Guide the design and manufacture of safe rollers (compactors) and attachments.
• Define factory test methods and acceptance criteria for noise and vibration for small rollers.
• Inform risk assessments and mitigation for commissioning, operation and maintenance.
• Support procurement specifications and compliance documentation for contractors and fleet owners.
• Serve as a reference for safety audits, operator training content and maintenance procedures.

Who should use this standard

• Manufacturers and design engineers of rollers and compactors
• Safety and compliance engineers in construction equipment companies
• Test laboratories evaluating noise, vibration and braking performance
• Fleet managers, procurement teams and contractors specifying safe machinery
• Standards writers and regulatory bodies harmonizing national rules with ISO guidance

Related standards

Key referenced standards include: ISO 20474‑1, ISO 6165, ISO 3450, ISO 13850, ISO 17063, ISO 20643, and ISO 8811. These provide general safety, terminology and specific test procedures that complement ISO 20474‑13:2017.
