Key bibliographic and lifecycle details summarized from ISO and recognized national catalogues.

Scope

This International Standard lays down the external and mounting dimensions for concave disks type D1 used on sowing and planting machines. It covers disks with or without a central hole, lists dimensions and fixing-hole patterns for specified size classes (I–IV), and provides an illustrative section view for dimensional reference. The specification is intended for use where interchangeability and correct mounting geometry are required.

Key topics and requirements

• Dimensional tables for concave disks type D1 (outer diameters, hole positions, thicknesses and radii).
• Specification of fixing-hole patterns and centre-hole options (with or without central hole).
• Classification by size (sizes I to IV) with associated mounting details.
• Illustrative figure showing section and critical dimensions for manufacturing and inspection.
• Intended for ensuring interchangeability of disks across sowing/planting equipment designs.

These requirement items are drawn from the International Standard's concise dimensional specification.

Typical use and users

Primary users: agricultural machinery manufacturers, component suppliers (disk makers), design engineers for sowing and planting equipment, maintenance and repair shops, procurement specialists specifying spare parts, and national standards bodies adopting or referencing ISO dimensions. The document is used when specifying replacement disks, designing mounting interfaces, or harmonizing parts across equipment ranges.
