Full title and description

ISO 10626:1991 — Equipment for crop protection — Sprayers — Connecting dimensions for nozzles with bayonet fixing. This International Standard specifies the connecting dimensions for flat spraying nozzles with a bayonet fixing to allow interchangeability; the drawing (Figure 1) in the standard illustrates the dimensions of concern. PDF distribution is available from ISO and national standards bodies.

Abstract

Specifies the dimensions necessary to permit interchangeability of flat spray nozzles with bayonet fixing used on agricultural sprayers. The standard defines the critical connecting dimensions (illustrated in Figure 1) and refers to ISO 8169 for the dimensions of the nozzle body.

• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 65.060.40 (Plant care equipment).
• Edition / version: Edition 1 — 1991.
• Number of pages: 1 (concise drawing and dimensional requirements).

Scope

This standard applies to flat spraying nozzles with bayonet fixing for agricultural sprayers and specifies the connecting dimensions required to ensure interchangeability between nozzle bodies and sprayer fittings. It does not replace or repeat detailed nozzle-body dimensions, which are covered by ISO 8169; instead ISO 10626 defines the mating/connecting geometry (see Figure 1).

Key topics and requirements

• Defined connecting dimensions for nozzles with bayonet fixing to ensure mechanical interchangeability.
• Reference to a figure illustrating the critical dimensions (Figure 1) used to verify compatibility.
• Interoperability focus — enables manufacturers and users to select and replace nozzles across different sprayers when the bayonet interface conforms to this standard.
• Normative relationship with ISO 8169 for nozzle-body dimensions; intended to be used together with related sprayer and nozzle standards.

Typical use and users

Manufacturers of agricultural sprayer nozzles and sprayer equipment, agricultural machinery designers, test laboratories, certification bodies, procurement teams specifying replacement parts, and maintenance technicians who require mechanical interchangeability of spray nozzles. The short, diagram-led nature of the standard makes it a practical reference when verifying or specifying bayonet-type nozzle fittings.

Related standards

Directly related standards and documents include ISO 8169 (dimensions of the nozzle body), other sprayer and safety standards in the ISO/TC 23 portfolio and regional/adopted equivalents (for example national adoptions such as NF ISO 10626:1992 and identical/adopted versions listed in standards catalogues). Also relevant: ISO 16119 series (sprayer environmental/testing requirements) and ISO 4254-6 (safety for sprayers) where functional and safety contexts overlap.

FAQ

Q: What is this standard?

A: ISO 10626:1991 is an international standard that specifies the connecting dimensions for flat spraying nozzles with bayonet fixing so they can be interchanged between sprayers and nozzle bodies.

Q: What does it cover?

A: It covers the geometric dimensions of the bayonet-style connection (illustrated in Figure 1 of the document) needed to ensure mechanical compatibility; detailed nozzle-body dimensions are covered by ISO 8169.

Q: Who typically uses it?

A: Nozzle and sprayer manufacturers, equipment designers, maintenance teams, testing/certification bodies, and procurement specialists specifying replacement nozzles.

Q: Is it current or superseded?

A: According to ISO's lifecycle information this edition (1991) remains published and was confirmed in the ISO periodic review process (confirmed most recently in the 2020s), i.e., it is current until formally withdrawn or revised by ISO. Users should check ISO or their national standards body for any more recent amendments or replacements.

Q: Is it part of a series?

A: It is part of the ISO portfolio covering equipment for crop protection and sprayers (ISO/TC 23/SC 6). It is intended to be used alongside related standards such as ISO 8169 (nozzle body dimensions) and other sprayer-related standards (e.g., ISO 16119, ISO 4254 series) for broader performance, testing and safety requirements.

Q: What are the key keywords?

A: Bayonet fixing, nozzle connecting dimensions, interchangeability, flat spray nozzle, agricultural sprayer, ISO 8169.
