Overview

prEN 1646-2 - Leisure accommodation vehicles - Motor Caravans - Part 2: User payload is a CEN (European Committee for Standardization) document that specifies how to calculate the minimum user payload designers must allow for when developing motor caravans. The standard also defines the user payload information that must appear in the motor caravan’s user handbook. It applies to motor caravans as defined in EN 13878.

This standard helps ensure consistent, transparent payload information and supports safe, compliant vehicle design, documentation, and consumer information.

Key Topics

• Method of calculation of minimum user payloads
  • Establishes an agreed procedure to determine the minimum payload capacity that must be available to users.
  • Ensures that design and specification account for occupants, personal effects, fluids, and typical equipment without compromising safety.
• User handbook requirements
  • Specifies what payload-related information must be provided to end users in the handbook.
  • Promotes clear communication of usable payload versus technical/structural mass.
• Scope and applicability
  • Applies specifically to motor caravans as per EN 13878 definitions.
  • Intended to be used during design, type-approval, and handover documentation processes.

Applications

Who uses prEN 1646-2 and how:

• Vehicle manufacturers and designers
  • Integrate the payload calculation into structural and layout design to meet minimum user payload requirements.
• Type-approval and certification bodies
  • Verify compliance with payload declaration and required handbook information.
• Test laboratories and engineers
  • Use the standardized method to evaluate and report usable payload capacities.
• Dealers and end users
  • Rely on consistent handbook information to plan loading, travel safety, and payload management.
• Aftermarket converters and upfitters
  • Ensure modifications do not reduce minimum required user payload or mislead consumers.

Practical benefits include improved safety (avoiding overload), consistent marketing claims, reduced warranty/ liability risk, and clearer consumer expectations.

Related Standards

• EN 13878 - Defines motor caravans referenced by prEN 1646-2.
• Other parts of the EN 1646 series (related documents) address complementary aspects of caravan/motor caravan design, safety, and testing.
