Saudi Energy Efficiency Update Affects Smart Irrigation Controller Certification

Saudi Arabia’s Standards, Metrology and Quality Organization (SASO) issued the revised Energy and Water Efficiency Standard for Electric Appliances (SASO 2663:2026) on May 20, 2026. Though primarily targeting washing machines, the update introduces new compliance requirements that indirectly impact exporters of smart irrigation controllers—particularly those with microprocessor-based logic units—entering Gulf markets.

New SASO Standard Introduces Two Key Compliance Requirements

On May 20, 2026, SASO published SASO 2663:2026, which—for the first time—mandates testing of smart control module power consumption as part of energy efficiency evaluation. Additionally, the standard explicitly requires all irrigation logic units incorporating microprocessors—including Drip Irrigation Logic controllers—to obtain IEC 62304 Class B software safety certification prior to market access in Saudi Arabia and other GCC member states. These provisions apply to products submitted for SASO conformity assessment after the effective date of the standard.

Cross-Chain Impacts Across Market Participants

Exporters and Trading Companies

Direct trade enterprises exporting smart irrigation devices to the Gulf must now align product documentation, test reports, and certification pathways with both SASO 2663:2026 and IEC 62304. The added software safety verification step extends overall certification lead time by approximately 45 days—potentially delaying shipment schedules and affecting contract fulfillment timelines.

Manufacturers and OEMs

Equipment manufacturers face revised design validation requirements: firmware architecture, runtime power profiling, and traceability of software development lifecycle processes must now meet IEC 62304 Class B criteria. This may necessitate internal process upgrades, third-party audit readiness, and updated technical file compilation—not just for hardware but for embedded control logic.

Component and Subsystem Suppliers

Suppliers providing microcontroller units, motor drivers, or programmable logic modules must ensure their components support verifiable software safety evidence (e.g., hazard analysis, traceability matrices, verification records). Buyers are increasingly requiring supplier declarations aligned with IEC 62304, shifting some compliance burden upstream.

Conformity Assessment and Certification Service Providers

Testing laboratories and notified bodies accredited for SASO and IEC 62304 must expand service offerings to cover integrated power consumption + software safety assessments. Capacity constraints and regional accreditation gaps may further contribute to certification delays in the near term.

Key Actions for Export-Ready Enterprises

Review and Update Certification Strategy

Confirm whether existing SASO CoC applications include IEC 62304 Class B coverage. For pending submissions, reassess timelines and allocate additional buffer for software safety audits, including source code review and hazard analysis documentation.

Validate Firmware Architecture Against IEC 62304

Ensure firmware development follows a defined life cycle model compliant with Class B, including documented risk management, configuration control, and verification of critical software functions—especially those governing pump activation, valve sequencing, and low-power sleep modes.

Reassess Power Consumption Testing Protocols

Expand energy testing beyond steady-state operation to include dynamic scenarios where smart modules transition between active, standby, and deep-sleep states. SASO 2663:2026 requires measurement of cumulative control-module power draw across representative irrigation cycles.

Align Technical Documentation with Dual Requirements

Consolidate technical files to simultaneously satisfy SASO’s energy labeling framework and IEC 62304’s software safety documentation structure—including software requirements specification, architecture diagram, verification report, and release notes with change history.

Industry Observation: Regulatory Convergence Is Accelerating

Analysis shows that SASO is increasingly harmonizing appliance-level standards with functional safety frameworks traditionally applied to medical or industrial systems. What deserves closer attention is how this reflects a broader GCC trend: energy regulations are evolving from pure efficiency metrics toward holistic system-level assurance—including embedded intelligence, real-time decision logic, and adaptive power behavior. From an industry perspective, this signals a structural shift—from component-level compliance to integrated system certification—as a prerequisite for market access.

Strategic Takeaway for Global Suppliers

This regulatory update does not introduce a new product category restriction, but rather redefines the baseline for ‘intelligent’ water management equipment in the Gulf. It underscores that software functionality is no longer ancillary—it is a regulated subsystem. Manufacturers who treat firmware as a compliance-critical element—not just a feature—will be better positioned to navigate future iterations of SASO, UAE ESMA, and other regional energy standards.
