• Evaluation process: Stepwise procedures for design review (hardware identification, sensors, data processing, communication interfaces)
• Performance testing: Standardized mounting and configuration protocols, influence quantity testing, environmental resilience, and diagnostics
• Fail-safe behaviour and dependability: Specification of safety behaviours under various fault and failure scenarios

Practical Implications

Adopting IEC 61514-2:2026 gives instrument suppliers and end-users:

• Concrete protocols for reporting and evidence generation
• Transparent, globally recognized performance benchmarks
• Structured approaches for integrating intelligent diagnostics and cyber-resilience
• Decision frameworks for repair strategies, redundancy, and preventive maintenance

Key highlights:

• Comprehensive checklist for intelligent positioner functionality, configuration, and diagnostics
• Coverage of Fieldbus and other communication interfaces
• Introduction of cyber-security testing and reporting

IEC TS 63086-2-5:2026 - Particle Loading Test for Air Cleaners

Household and similar electrical air cleaning appliances — Methods for measuring the performance — Part 2-5: Particular requirements for determination of the performance change by loading with particles

This technical specification defines standardized methods for assessing how exposure to particles affects the performance of household or similar air cleaning appliances. Manufacturers of air purifiers must understand how their products’ performance changes when filters and air-cleaning modules are loaded over time—crucial for safety, efficacy, and honest communication to end-users.

Scope and Application

IEC TS 63086-2-5:2026 applies to:

• Electrically powered household and similar air cleaning appliances
• Evaluation of performance drop using particle loading (i.e., build-up on filters)

Testing is designed to allow fair, repeatable comparison across products under controlled conditions, although results may not mirror all real-world situations due to variability in household particle types and concentrations.

Target organizations: Appliance manufacturers, filtration material suppliers, testing labs, indoor air quality consultants.

Key Technical Requirements & Testing Protocol

This specification covers:

• Definitive methods for applying and measuring particle loads (aerosols, dust, cigarette smoke, salt, or specified mixes)
• Use of precision equipment such as optical particle counters and analytical balances
• Steps for determining the Cumulative Clean Mass (CCM)—the filter mass loading at which the Clean Air Delivery Rate (CADR) drops by 50%
• Calculation protocols and interpolation steps for accurate reporting
• Requirements for clear documentation of test conditions, aerosol types, and results

Practical Implications

IEC TS 63086-2-5:2026 enables product developers to:

• Provide valid, comparable data for device certification and consumer labeling
• Better estimate filter replacement intervals and overall air cleaner lifecycle
• Innovate in filter technology based on robust, reproducible performance metrics
• Ensure readiness for regulatory and retail requirements in markets favoring standardized test results

Key highlights:

• Detailed procedures for calculating cumulative clean mass (CCM)
• Flexible protocols for different aerosol types (salt, dust, smoke)
• Guidance for reporting and documenting all influencing test variables
