[Old Standard: EN 1525] ──► Highly focused on fixed-path AGVs. │ ▼ [Current Standard: ISO 3691-4] ──► Expanded to cover dynamic AMRs, complex zones, and human coexistence. Major Advancements in the Current Standard
: AGVs, AMRs, automated carts, tunnel tuggers, and bots.
Key technical requirements (400–600 words)
ISO 3691-4 classifies the operating environment into different zones based on visibility, clearance, and human access. Manufacturers and operators must design system behaviors according to these zones:
Safety-related control systems must meet specific performance levels (usually PLd) under ISO 13849-1. This ensures that critical systems, like emergency stops and braking, rarely fail. iso 36914 pdf
is the primary international safety standard for driverless industrial trucks , including Automated Guided Vehicles (AGVs) and Autonomous Mobile Robots (AMRs) . The most recent version, published in 2023 , technically revises and replaces the previous 2020 edition. Core Scope and Purpose
For professionals in the timber and construction industry, this document was essential for procurement. It provided a common language between manufacturers (sawmills) and end-users (architects, builders).
Imagine e-discovery that surfaces contract clauses with confidence scores tied to document validation; or enterprise search that links technical drawings to BOMs because both follow the same structural rules. The standard becomes a multiplier for AI utility.
A core requirement is that driverless trucks must detect obstacles and stop immediately. The standard requires: [Old Standard: EN 1525] ──► Highly focused on
It accounts for robots that change paths autonomously to avoid obstacles.
These are common areas where humans, manual forklifts, and automated trucks coexist. In shared spaces, strict speed limits apply, and the vehicle's personnel detection fields must be fully active. Hazard Zones
ISO 3691-4 is the cornerstone of safety for automated material handling. By defining clear requirements for the design, operation, and verification of driverless trucks, it enables the safe, efficient integration of automation technology in warehouses and factories.
The standard specifies measures for various hazards throughout the life cycle of the truck, including: is the primary international safety standard for driverless
Always purchase standards from official or authorized retailers. Free PDFs found on file-sharing sites or less reputable websites are often outdated, watermarked incorrectly, or contain errors. Using a non-authentic version can lead to non-compliance and significant safety risks. The official PDF from ISO is a secure document that may require a plugin (like FileOpen) to view and comes with digital rights management (DRM) restrictions, such as limits on the number of devices it can be viewed on or the number of times it can be printed.
