IEC TS 63086-2-5:2026 Household and similar electrical air cleaning appliances

Basic Standard Profile

Full Title: 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

Edition: Technical specification released in 2026 by IEC

Standard Positioning: Specialized subsection under the IEC 63086 air cleaner performance measurement system, unifying test rules for evaluating performance attenuation of household air cleaners under particulate accumulation

IEC TS 63086-2-5:2026 is an international technical specification developed by the International Electrotechnical Commission (IEC). It focuses on standardizing test methods for measuring the performance change of household and similar electrically powered air cleaning appliances when exposed to particulate loading. The primary goal is to facilitate objective comparison of air cleaner degradation due to particle accumulation, although test conditions may not fully simulate all real-world environments.

By establishing a consistent methodology, the standard ensures that manufacturers, testing laboratories, and regulatory bodies can reliably assess and compare how various air cleaners maintain clean air delivery as filters or cleaning modules are loaded with particles such as dust, smoke, salt aerosols, or oil-based droplets.

Core Covered Topics

Performance Change Measurement

The specification details repeatable test methods to track performance reduction in air cleaners as they are incrementally loaded with particles.

Types of Loading Aerosols

It addresses the effects of various particle types including salt (NaCl/KCl), standardized dust, cigarette smoke, and DEHS oil aerosols, reflecting diverse real-world pollutants.

Cumulative Clean Mass (CCM)

Defines how the reduction of the clean air delivery rate (CADR) to 50% of its initial value is used to determine the filter or device’s particle retention capability.

Testing Approaches

Module-Only Loading: For appliances with replaceable filter modules.

Whole Device Loading: For integrated or non-replaceable designs, by exposing the whole unit in a test chamber.

Instrumentation

Specifies required equipment, such as aerosol generators, optical particle counters, and precision balances, to ensure consistency and accuracy of CADR and CCM measurements.

Reporting Requirements

Outlines essential information to include in test reports, promoting transparency and repeatability.

Primary Application Scenarios

Product Development

Manufacturers can use the standardized loading protocols to optimize filter materials, predict service intervals, and benchmark different models or technologies.

Certification & Market Access

Enables third-party labs and certification bodies to perform comparable product testing and support compliance claims for global markets.

Consumer Guidance

Results generated via this method help consumers and institutions make informed choices based on how quickly air cleaner effectiveness may decline with use.

Procurement

Facility managers, purchasing agents, and government organizations can use test data to select air cleaners that maintain performance over longer periods.

Research & Comparative Studies

Academic or industrial researchers can apply the method to study filtration dynamics, validate new technologies, or perform head-to-head comparisons of air purification products.

Reference Standards

IEC 63086-1:2020 Household and similar electrical air cleaning appliances - Methods for measuring the performance - Part 1: General requirements, the core standard defining universal test procedures for air cleaners.

IEC 63086-2-1:2024 Particular requirements for determination of particle reduction, specifying dedicated protocols for airborne particle removal efficiency testing.
