What is ISO 3691-4 about?
ISO 3691-4 discusses safety requirements for industrial trucks. ISO 3691-4 specifies safety requirements and the means for their verification for driverless industrial trucks (hereafter referred to as trucks) and their systems. ISO 3691-4 also contains requirements for driverless industrial trucks which are provided with:
- Automatic modes which either require operators’ action(s) to initiate or enable such automatic operations
- The capability to transport one or more riders (which are neither considered as drivers nor as operators)
- Additional manual modes which allow operators to operate the truck manually; or
- A maintenance mode that allows manual operation of truck functions for maintenance reasons
Note 1: It does not give requirements for additional hazards that can occur:
- During operation in severe conditions (e.G., Extreme climates, freezer applications, strong magnetic fields)
- During operation in nuclear environments
- From trucks intended to operate in public zones (in particular ISO 13482);
- During operation on a public road
- During operation in potentially explosive environments
- During operation in military applications
- During operation with specific hygienic requirements
- During operation in ionizing radiation environments
- During the transportation of (a) person(s) other than (the) intended rider(s)
- When handling loads the nature of which can lead to dangerous situations (e.G., Molten metals, acids/ bases, radiating materials)
- For rider positions with elevation function higher than 1 200 mm from the floor/ground to the platform floor.
Note2: ISO 3691-4 does not contain safety requirements for trailer(s) being towed behind a truck.
Note3: ISO 3691-4 does not contain safety requirements for elevated operator trucks.
Who is ISO 3691-4 for?
ISO 3691-4 is of relevance, in particular, for the following stakeholder groups representing the market players with regard to machinery safety:
- Machine manufacturers (small, medium, and large enterprises)
- Health and safety bodies (regulators, accident prevention organizations, market surveillance, etc.)
- Machine users/employers (small, medium, and large enterprises)
- Machine users/employees (e.G., Trade unions, organizations for people with special needs)
- Service providers, e.G., For maintenance (small, medium and large enterprises)
- Consumers (in the case of machinery intended for use by consumers).
Why should you use ISO 3691-4?
For the purposes of ISO 3691-4, a driverless industrial truck is a powered truck, which is designed to operate automatically. A driverless truck system comprises the control system, which can be part of the truck and/or separate from it, guidance means, and power system.
In order to properly design a product and to cover all specific safety requirements, the manufacturer needs to identify the hazards that apply to their product and carry out a risk assessment.
ISO 3691-4 specifies safety requirements and the means for their verification for driverless industrial trucks (hereafter referred to as trucks) and their systems.
ISO 3691-4 deals with all significant hazards, hazardous situations or hazardous events during all phases of the life of the truck (ISO 12100:2010, 5.4) to the applicable machines when it is used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer.
