ISO 6661:1983

Overview

ISO 6661:1983 is an international standard established by the International Organization for Standardization (ISO) that provides comprehensive guidance on the arrangement of parallelepipedic packages containing fresh fruits and vegetables in land transport vehicles. This standard applies to packages regardless of their material composition and whether they are covered or uncovered. It covers both non-palletized and palletized packaging, aiming to optimize packaging stability, product protection, and airflow during transport.

This standard is fundamental for stakeholders involved in the agricultural food supply chain, including manufacturers, packers, logistics providers, and transport operators. Adhering to ISO 6661 enhances the preservation of fresh produce quality during land transport, minimizes damage, and improves load stability and safety.

Key Topics

• Scope and Applicability
  ISO 6661 applies specifically to parallelepipedic (rectangular box-shaped) packages of fresh fruits and vegetables, offering detailed recommendations for their disposition in transport vehicles, whether palletized or non-palletized.

• Definitions
  The standard clarifies key terms such as:

  • Pile: a stack of packages placed on top of each other on the same base package
  • Row: packages arranged side by side on the same level

• General Recommendations for Non-Palletized Packages

  • Packages must allow for stable stacking and secure loading.
  • Packages should facilitate air circulation, particularly if covers are absent.
  • Loads must be continuous along the vehicle length without gaps, and rest firmly against vehicle end walls.
  • The top layer of packages should be uniform in height.
  • Rows should be tightly packed transversely but allow longitudinal air flow.
  • Alternating rows should rest against opposite side walls to maximize space and stability.

• Specific Arrangements for Mixed Loads

  • Different types of packages or products should be grouped into homogeneous lots and secured separately.
  • Heavier and less fragile goods are loaded on bottom layers.
  • Load weight should be distributed evenly across vehicle axles.

• Palletized Packaging Guidelines

  • Packages on palettes should be uniform in dimensions and tightly arranged without gaps.
  • The package layout on the palette should optimize surface area usage and create stable stacks.
  • Pallet loads are arranged in rows of two or three, oriented to maximize vehicle space and maintain stability.
  • Any residual space within pallets or between pallets and vehicle walls should be filled with appropriate cushioning materials.
  • Palletized loads should rest firmly against vehicle end walls with no discontinuities along the load length.
  • Use of securing devices like straps at mid-height and near the top to prevent package displacement is recommended.

• Load Securing and Safety
  Measures such as corner protectors, horizontal straps, and filling voids ensure packages do not shift during transport, especially when packages are uncovered or of small size.

Applications

ISO 6661:1983 is essential for the fresh produce industry including:

• Agricultural producers and packers designing shipping packages for fresh fruits and vegetables.
• Logistics and transport companies responsible for loading arrangements to maintain product quality and reduce damage during land transport.
• Warehouse and distribution centers optimizing storage and loading practices in transport vehicles.
• Regulatory agencies and quality auditors assessing compliance with packaging and transport safety standards.
• Suppliers of packaging materials seeking to understand packaging stability requirements for fresh fruits and vegetables.

By following ISO 6661, organizations ensure better load optimization, product protection, and air circulation management, which is critical for the shelf-life of perishable goods during transit.

Related Standards

  This standard complements ISO 6661 by specifying dimensions for rigid rectangular packages, ensuring compatibility with transport and storage systems.

• ISO 3676: Packaging - Unit loads - Dimensions
  Provides guidelines for unit loads dimensions, which are vital when considering palletized packaging arrangements addressed by ISO 6661.

Conclusion

ISO 6661:1983 plays a crucial role in the efficient and safe land transport of fresh fruits and vegetables packed in parallelepipedic containers. It focuses on practical loading arrangements that enhance product preservation, load stability, and air circulation. Implementation of this standard ensures reduced waste, safer transport, and higher customer satisfaction in the fresh produce supply chain.
