CTI Leads Two New ISO Standards for Agri-Drones and Smart Irrigation Testing

On June 1, 2027, two new ISO draft standards—ISO/CD 25678 and ISO/CD 25679—will enter the final review phase, establishing the first internationally harmonized test benchmarks for pesticide application accuracy in agricultural drones and nutrient solution uniformity in smart irrigation systems. These standards directly affect manufacturers and exporters targeting the EU and Southeast Asian markets, where compliance will soon become a mandatory type-approval requirement.

Standardization Milestone Confirmed at ISO Working Group Meeting

On May 20, 2026, CTI Certifications (China) served as convenor of ISO/TC34/SC6/WG28—the International Organization for Standardization’s Working Group on Pesticide and Veterinary Drug Residue Analysis—and chaired its third plenary meeting. During this session, the group formally approved the立项 (project initiation) of two draft standards: ISO/CD 25678: Test method for liquid dosage accuracy of unmanned aerial vehicle (UAV) spraying systems and ISO/CD 25679: Online assessment specification for mixing uniformity of fertilizer solutions in smart irrigation systems. Both documents are scheduled for publication in Q2 2027.

Impact Across the Agricultural Technology Supply Chain

Export-oriented equipment manufacturers

Manufacturers of Agri-Drones and Smart Irrigation systems exporting to the EU or ASEAN must now align product design, calibration protocols, and factory testing procedures with the upcoming ISO/CD 25678 and ISO/CD 25679 requirements. Non-compliance may result in rejected customs entries or failed conformity assessments under regional regulatory frameworks.

Component and subsystem suppliers

Suppliers of flow sensors, dosing pumps, real-time monitoring modules, and closed-loop control units face revised technical specifications. Their components must support traceable, repeatable measurement outputs compatible with the standardized test conditions defined in both drafts—especially under variable field operating conditions.

Contract manufacturing and assembly service providers

Firms offering OEM/ODM services for precision agtech devices need to integrate new verification checkpoints into production line quality gates—including pre-shipment metrological validation per ISO/CD 25678 Annex B and dynamic uniformity logging per ISO/CD 25679 Clause 7.2.

Logistics and certification support providers

Third-party testing labs, notified bodies, and export documentation agencies must prepare updated test reports, CE/ASEAN Declaration of Conformity templates, and technical file structures reflecting the new metrological criteria—particularly for UAV spray drift quantification and irrigation solution homogeneity thresholds.

Key Actions for Enterprise Compliance Preparation

Align internal metrology with upcoming ISO test protocols

Organizations should benchmark current calibration practices against the draft test setups described in ISO/CD 25678 (e.g., simulated wind tunnel dosing trials) and ISO/CD 25679 (e.g., inline conductivity profiling across irrigation manifolds). Early alignment reduces rework risk post-publication.

Review and update technical tender submissions

Bid documents for public procurement in EU member states and ASEAN countries increasingly reference ISO/IEC 17025-accredited test reports. Manufacturers must ensure future tenders explicitly cite compliance pathways toward ISO/CD 25678 and ISO/CD 25679—even if referenced as ‘under development’—to maintain competitive eligibility.

Strengthen supplier technical documentation management

Downstream integrators must require certified metrological traceability from component vendors—especially for pressure-compensated emitters, volumetric dispensers, and real-time turbidity sensors—since ISO/CD 25679 mandates documented uncertainty budgets for all measurement inputs used in online uniformity evaluation.

Industry Observation: From Fragmented Validation to System-Level Metrology

Analysis shows that ISO/CD 25678 and ISO/CD 25679 represent a structural shift—from device-level functional claims to system-level metrological accountability in precision agriculture hardware. Observably, this raises the bar not only for hardware performance but also for embedded software validation, data integrity assurance, and audit-ready digital test logs. It is more appropriate to understand this as the beginning of formalized ‘measurement chain governance’ across the agtech value chain—not merely a new set of pass/fail tests. What deserves closer attention is how national regulators in target markets will translate these ISO drafts into legally enforceable technical requirements within their respective conformity assessment schemes.

Toward Harmonized Global Market Access

This initiative marks a pivotal step in reducing technical barriers for precision agtech trade. While neither standard introduces novel safety or environmental limits, their role as binding type-test references elevates consistency, comparability, and transparency across global supply chains. The outcome is not regulatory overreach—but rather a shared language for verifying what ‘accurate’ and ‘uniform’ truly mean in field-deployed systems.
