ISO 15644:2002

Overview

ISO 15644:2002 - "Road construction and maintenance equipment - Chippings spreaders - Terminology and commercial specifications" defines standardized terminology and the technical and commercial information to be supplied for chippings spreaders used in road construction and surface coating. The standard covers machine types, main assemblies, performance characteristics and methods of operation so manufacturers, purchasers and road authorities share a common specification and vocabulary for chippings spreaders.

Key Topics

• Scope and purpose: Establishes terms and the type of technical/commercial specifications required for chippings spreaders used in road surface coating.
• Types of chippings spreaders: Defines three main types - transported, self‑propelled, and pushed by tipper truck - and their distinguishing features.
• Main assemblies and components:
  • Dumping body and partial partitions
  • Chippings spreading device (delivery/spreading rollers, conveyors)
  • Receiving and spreading hoppers
  • Feed systems and diffusers
  • Control station and power plant
• Operational descriptions:
  • Extraction/distribution methods (roller or conveyor extraction vs. gravity distribution)
  • Adjustment of chippings flow (flow blade, roller/conveyor speed)
  • Adjustment of spreading width (bin gates, slanting blades, expandable hoppers)
  • Automatic control options (linking roller/conveyor speed or flow blade opening to vehicle speed)
  • Diffuser types (smooth/partitioned, flat/curved; folding flap extensions)
• Dimensional and mass specifications: Requirements for specifying transport and working dimensions (clearance, overhangs, spreading width, hopper capacities) and mass characteristics (kerb mass, laden mass, carrying capacity).
• Safety reference: Points to EN 13020 for safety requirements of road‑surface treatment machines.

Applications

ISO 15644 is practical for:

• Manufacturers drafting product datasheets and design briefs for chippings spreaders.
• Procurement teams and contracting authorities preparing tender specifications for road construction and surface coating projects.
• Fleet operators and road maintenance crews evaluating machine compatibility, capacity and operational controls.
• Inspection, testing and compliance bodies ensuring delivered equipment meets agreed commercial specifications.
• Equipment designers and service engineers standardizing interfaces (hoppers, tow hooks, control stations) and optimizing performance (flow control, vehicle‑speed linkage).

Using ISO 15644 supports consistent procurement, improved interoperability, predictable performance and clearer communication across the road construction equipment supply chain.
