Iso 3691-4 Pdf - |best|

The ISO 3691-4 standard is the primary international safety benchmark for driverless industrial trucks, including Automated Guided Vehicles (AGVs) and Autonomous Mobile Robots (AMRs). Published originally in 2020 and updated in 2023, it provides a rigorous framework for safe design, integration, and operational verification. 1. Scope and Core Definitions

The standard specifies requirements for any powered truck designed to operate automatically, covering the truck itself and its separate or integrated control and guidance systems.

Target Machinery: Includes AGVs, AMRs, bots, tunnel tuggers, and under-carts.

Operating Modes: Covers automatic mode, automatic mode with a rider, manual mode, and maintenance mode.

Exclusions: It does not apply to trucks guided solely by mechanical means (e.g., rails), remotely-controlled trucks, or operations in severe environments like nuclear or explosive zones. 2. Key Safety Pillars

ISO 3691-4 categorizes safety into three main areas to ensure a unified approach to risk management:

ISO 3691-4:2023 is the definitive international safety standard for driverless industrial trucks, a category that includes Automated Guided Vehicles (AGVs), Autonomous Mobile Robots (AMRs), and automated forklifts. Published by the International Organization for Standardization (ISO), this "Type C" standard provides manufacturers and operators with a rigorous framework for risk assessment, safety-related control systems, and operational validation in shared human-robot environments. Scope and Applicability

The standard specifies requirements for the safe design, integration, and verification of driverless trucks and their associated systems.

Vehicles Covered: AGVs, AMRs, automated guided carts (AGCs), tunnel tuggers, and bots.

Operational Modes: It applies to fully automatic operation, manual modes for intervention, and dedicated maintenance modes.

Key Exclusions: The standard does not cover trucks guided solely by mechanical means (like rails), remotely controlled vehicles, or operations in extreme environments such as nuclear zones, explosive atmospheres, or public roads. Key Safety Requirements

ISO 3691-4: The Definitive Safety Standard for Driverless Industrial Trucks

The ISO 3691-4 standard, titled "Industrial trucks — Safety requirements and verification — Part 4: Driverless industrial trucks and their systems," is the primary international safety benchmark for Automated Guided Vehicles (AGVs) and Autonomous Mobile Robots (AMRs). First published in 2020 and updated in June 2023, it provides a rigorous framework for designing, integrating, and operating autonomous material handling equipment in industrial environments.

For professionals seeking the official documentation, the ISO 3691-4 PDF can be purchased from authorized distributors such as Accuris ($259) or the ISO Store. Core Scope and Application

The standard applies to a broad family of "driverless industrial trucks," which include:

AGVs and AMRs: Including automated guided carts, "bots," tunnel tuggers, and under-carts.

System Components: It covers the truck itself, its control system (onboard or remote), guidance means, and power systems.

Operating Modes: Requirements are defined for automatic, manual, and maintenance modes.

Exclusions: It does not apply to trucks guided solely by mechanical rails, remotely controlled vehicles, or operation in extreme environments like nuclear zones or public roads. Key Safety Requirements

ISO 3691-4 uses Performance Levels (PL) as defined in ISO 13849-1 to specify the reliability of safety functions. 1. Personnel Detection Systems

The truck must detect persons in its path across its entire width and load. It must be designed to stop the vehicle before any rigid part makes contact with a person. Performance Level: Typically requires PLr d.

Physical Protection: Must include pressure-sensitive bumpers to detect physical contact. 2. Braking and Speed Control

The braking system must be "fail-safe," activating automatically upon power loss or loss of speed/steering control.

Overspeed Protection: The truck must initiate an emergency stop if it exceeds its rated speed.

Stopping Distance: The system must ensure the truck stops within the detection range of its sensors, accounting for floor conditions and load. 3. Hazard Zones and Clearances The ISO 3691-4 standard is the primary international

ISO 3691-4:2023 is the latest international safety standard for driverless industrial trucks, including automated guided vehicles (AGVs), autonomous mobile robots (AMRs), and their systems. It provides the essential safety requirements and verification methods for these machines to operate safely alongside humans in industrial environments. Key Features of ISO 3691-4 ISO 3691-4:2020 A Standard for Automated Guided Vehicles.

ISO 3691-4:2023 is the definitive international safety standard for driverless industrial trucks, covering everything from Automated Guided Vehicles (AGVs) to Autonomous Mobile Robots (AMRs). The 2023 update is particularly significant as it is now a harmonized standard in the EU, meaning compliance provides a "presumption of conformity" for CE marking. Key Highlights of the 2023 Update

ISO 3691-4:2023 sets the international safety standards for driverless industrial trucks, covering design, construction, and operational requirements to ensure safe human-machine interaction. It establishes mandatory criteria for safety functions, environmental validation, braking, and system verification for AGVs and AMRs. Learn more at Rocla AGV.

How to Use the Standard Effectively

Once you have the official PDF, do not just read it cover-to-cover. Instead:

  1. Identify your truck type: Clause 4 ("Safety requirements and/or protective measures") is organized by hazard type.
  2. Focus on Annexes: Annex A (Hazard list) and Annex E (Verification of safety functions) are goldmines for creating a risk assessment checklist.
  3. Check the normative references: ISO 3691-4 references other standards (like ISO 13849 for control system safety). You may need those PDFs too.

ISO 3691-4 vs. Regional Regulations (ANSI/ITSDF B56.5)

If you are in North America, you will often see a related standard: ANSI/ITSDF B56.5 (Safety Standard for Driverless, Automatic Guided Industrial Vehicles and Automated Functions).

While ISO 3691-4:2020 and ANSI B56.5 are "harmonizing" (moving closer together), they are not identical.

  • ISO 3691-4 is required for CE Marking (Europe) and increasingly for global export.
  • ANSI B56.5 is still the required standard for OSHA compliance in the USA.

Best Practice: If you are a global manufacturer, you need a PDF of both. However, the ISO version is often more strict regarding electromagnetic immunity (EMC) and software validation.

Clause 4: Safety Requirements and/or Protective Measures

This is the heart of the standard. It mandates:

  • 4.2 : Emergency stop – Must be category 0 or 1 stop per IEC 60204-1. Remote emergency stops (wireless) require specific reliability calculations.
  • 4.3 : Warning devices – Acoustic and visual signals must activate before motion.
  • 4.4 : Travel path safety – For fixed-path AGVs: minimum clearance formula. For free-ranging AMRs: protective field sets must adapt to speed (speed-dependent safeguarding).
  • 4.5 : Load handling – Preventing unintended load release. Forks must verify engagement before lifting.

Common Mistakes When Downloading "Free" PDFs

Let’s address the elephant in the room. Google "ISO 3691-4 PDF" and you will find Chinese rehosters, Russian translation sites, and obscure document libraries.

The risks of free PDFs:

  1. Obsolete text: You might be using the 2014 draft, missing the 2020 cybersecurity clause.
  2. Missing Annexes: Often, free PDFs strip out the "Verification" tables (how to test the brakes).
  3. Legal Liability: In a lawsuit, if you reference a pirated standard, a lawyer will argue you were not "duly diligent" in obtaining correct safety data.

Red-Flag Warning: If the PDF does not have the ISO copyright footer on the bottom left of every page, it is fake.

4.1 General Safety Principles

The standard mandates a risk assessment process (per ISO 12100) for the manufacturer. The truck must be designed to prevent hazards during all modes of operation:

  • Automatic operation.
  • Maintenance mode.
  • Manual override (if applicable).
