Overview
ISO 10626:1991, "Equipment for crop protection - Sprayers - Connecting dimensions for nozzles with bayonet fixing," defines the connecting dimensions required to ensure interchangeability of flat spraying nozzles that use a bayonet fixing on agricultural sprayers. Published by ISO Technical Committee ISO/TC 23 (Sub‑Committee SC 6), the standard sets the geometric interface (dimensions in millimetres, illustrated in Figure 1) that nozzle and sprayer manufacturers should follow. For the complete nozzle‑body geometry, ISO 8169 is referenced.
Key topics and requirements
- Scope: Applies specifically to flat spraying nozzles with bayonet fixing for agricultural sprayers and aims to permit mechanical interchangeability.
- Connecting dimensions: Specifies the interface dimensions (in millimetres) that mating parts-nozzle and sprayer-must conform to. The standard includes an illustrative figure showing the dimensions of concern.
- Normative reference: ISO 8169 is cited for the detailed dimensions of the nozzle body; users must consult that document for full nozzle geometry.
- Interchangeability focus: The core requirement is compatibility between different manufacturers’ nozzles and sprayer fittings when the bayonet fixing form is used.
- Publication context: First edition, 1991; prepared by ISO TC 23/SC 6.
Applications and who uses it
ISO 10626:1991 is practical for stakeholders involved in the design, manufacture, procurement, maintenance, and regulation of crop‑protection equipment:
- Sprayer manufacturers ensure their fittings are compatible with standard bayonet‑type nozzles.
- Nozzle producers and aftermarket suppliers design nozzle outlets and retaining features to the standard dimensions to guarantee cross‑brand fit.
- Farm equipment designers and OEMs use the standard to specify interface details in product drawings and BOMs.
- Maintenance technicians and farm managers benefit from standardized nozzles for easy replacement, reduced downtime, and simplified spare‑parts stocking.
- Regulators and procurement teams reference the standard when specifying technical requirements for tenders and certification.

Note: Always verify whether a more recent edition or successor standard has been published before specifying ISO 10626:1991 in new designs or procurement documents.
