. As industries increasingly adopt autonomous fleets to optimize logistics and manufacturing, this standard provides a critical framework for ensuring safe human-machine interaction in complex environments. Live Electronics 1. Scope and Technical Requirements

The standard specifies safety requirements and verification methods for powered driverless trucks and their control systems. It covers a wide range of autonomous platforms such as: ISO - International Organization for Standardization

ISO 3691-4:2023 is the primary international safety standard for driverless industrial trucks, including automated guided vehicles (AGVs) and autonomous mobile robots (AMRs). It provides a comprehensive framework for manufacturers and operators to ensure these machines operate safely in industrial environments. Scope and Applications

The standard applies to various automated vehicles used for material handling, such as:

Automated Guided Vehicles (AGVs) and Autonomous Mobile Robots (AMRs). Automated Forklift Trucks and tuggers.

Vehicles with automatic modes that require operator initiation or can carry riders. Maintenance modes allowing for manual operation.

It does not cover trucks guided purely by mechanical means (like rails), remotely-controlled vehicles, or those used in public areas or explosive environments. Core Safety Requirements Iso 3691-4 Pdf

ISO 3691-4 aligns with ISO 13849 to define required Performance Levels (PLr) for safety functions. Key technical areas include: ISO 3691-4:2020 A Standard for Automated Guided Vehicles.

ISO 3691-4:2023 is the international safety standard for driverless industrial trucks, covering the design, construction, and operation of AGVs and AMRs. This updated edition focuses on risk management, personnel detection, and specific safety functions, with a new co-responsibility matrix for manufacturers and users.

ISO 3691-4:2023— Driverless Industrial Trucks - The ANSI Blog

ISO 3691-4:2023 is the international gold standard for the safety of Driverless Industrial Trucks and their systems. Often sought in PDF format by safety engineers and plant managers, this standard outlines the rigorous requirements for the design, construction, and installation of Automated Guided Vehicles (AGVs) and Autonomous Mobile Robots (AMRs). What is ISO 3691-4?

This standard provides the framework for ensuring that "driverless" vehicles can operate safely in environments where humans are present. It bridges the gap between traditional industrial truck safety and the complex software-driven world of robotics. Core Pillars of the Standard

Hazard Identification: It requires a comprehensive risk assessment of the entire operating environment, not just the machine itself.

Performance Levels (PL): Safety functions (like emergency stops and personnel detection) must meet specific reliability ratings, typically aligning with ISO 13849.

Operating Zones: It defines specific rules for different areas, such as:

Hazard Zones: Areas with restricted clearance where extra precautions are needed. ISO 3691-4:2023 is the latest international safety standard

Shared Zones: Areas where robots and humans interact freely.

Environmental Validation: Testing how the vehicle handles floor conditions, lighting changes, and obstacles in its specific workspace. Why the PDF is Essential for Teams

For companies transitioning to Industry 4.0, having the ISO 3691-4 PDF on hand serves as:

A Design Blueprint: Ensuring R&D teams build machines that are compliant from day one.

A Procurement Checklist: Helping buyers verify that third-party AGV vendors meet global safety benchmarks.

Liability Protection: Following these guidelines is often a prerequisite for insurance and regulatory compliance in many regions. How to Access the Official PDF

Because ISO standards are protected by copyright, you can obtain the official, updated PDF through these authorized channels:

ISO Store: The direct source for the most recent 2023 version.

National Standards Bodies: Organizations like ANSI (US), DIN (Germany), or BSI (UK) provide localized versions. ISO Store (iso

IHS Markit/Techstreet: Licensed third-party resellers often used by engineering firms for document management.

How to Get the Official ISO 3691-4 PDF (Legally)

You cannot rely on random forum links for safety standards. Here is the legitimate supply chain for the document:

ISO Store (iso.org): The official source. You can buy a PDF that downloads immediately. Cost is approximately 138 CHF (Swiss Francs) (~$150 USD). Access is often restricted to a single user.
ANSI Webstore (USA): The American National Standards Institute resells the ISO standard. It is identical text, just rebranded.
Local Standards Bodies: BSI (UK), DIN (Germany), or JSA (Japan) offer regional pricing.
Subscription Services: TechStreet or IHS Markit offer annual subscriptions if you need access to all ISO parts (3691-1 through 6).

Warning on "Preview" PDFs: Many sites offer a red-lined "Preview" PDF. This is legal but useless for engineering. It lacks the normative references (the calculations for safety distances). You cannot certify a machine with a preview.

ISO 3691-4 (overview and comprehensive discourse)

3. Braking Systems

The PDF details strict "worst-case scenario" braking. If the guidance is lost (e.g., a magnet is missing) or the safety controller fails, the truck must come to a controlled stop. It cannot simply "free wheel" or crash.

Relationship to other standards and frameworks

Complements ISO 3691-1 (safety requirements for powered industrial trucks with drivers) and other parts of ISO 3691 that address specific categories.
Interfaces with ISO 12100 (general machine safety — risk assessment and risk reduction) and ISO 13849 / IEC 61508 (functional safety of control systems) for safety-related control system design.
May reference ISO 23875 / ISO 17458 or other standards for sensor performance, plus industry-specific guidance for logistics automation and intralogistics.
Often used alongside workplace safety regulations and national occupational safety standards.

Introduction: Why ISO 3691-4 Matters in 2024 and Beyond

As warehouses and factories race toward automation, the sight of a driverless forklift maneuvering through aisles is no longer science fiction—it is the new standard. However, with autonomy comes a complex web of safety concerns. How do you ensure a robot weighing several tons operates safely alongside human workers?

The answer lies in ISO 3691-4. Officially titled "Industrial trucks – Safety requirements and verification – Part 4: Driverless industrial trucks and their systems," this international standard is the cornerstone of safety for Automated Guided Vehicles (AGVs) and Autonomous Mobile Robots (AMRs) in industrial settings.

For safety officers, automation engineers, and facility managers, accessing an ISO 3691-4 PDF is the first critical step toward compliance. But simply finding the document is not enough. You need to understand its structure, its mandatory requirements, and how to implement them.

This article provides a deep dive into ISO 3691-4, explains how to obtain the official PDF, breaks down the key clauses, and clarifies the difference between the 2020 version and the recent 2024 amendment.
