IEC 63086-2-1:2024

Overview

IEC 63086-2-1:2024 - Household and similar electrical air cleaning appliances - Methods for measuring the performance - Part 2-1: Particular requirements for determination of particle reduction - specifies laboratory test methods to quantify how effectively electrically powered household and similar air cleaners remove particulate pollutants. The standard defines aerosols, measurement instrumentation, calculation procedures and acceptance criteria used to determine particle reduction performance metrics such as the clean air delivery rate (CADR) and decay constants for particle number concentration.

Key Topics

• Scope and purpose: Test methods for electrically powered household and similar air cleaners intended to reduce particles.
• Test aerosols: Defined aerosols include salt (KCl), smoke, dust, and pollen for different particle size ranges and test conditions.
• Measurement instrumentation: Guidance on appropriate particle counters and optical instruments, and maximum background particle concentrations.
• Test chamber and execution: Requirements for aerosol generation, mixing/homogenization, test duration and data-point collection for reliable decay measurements.
• Calculation procedures: Methods to calculate decay constants, regression analysis, sample standard deviation of slopes, and derivation of CADR and its uncertainty.
• Acceptance criteria & limits: Criteria for acceptability of runs, outlier handling, measurability limits for maximum/minimum CADR (Annex A), and statistical limits for natural and total decay.
• Annexes and normative appendices: Practical content includes chamber cleaning procedures, long-term pollutant storage guidance, test report templates, derivation of effective room size, power measurement in maximum-performance mode, and an alternative fine particle size range.

Applications and Users

Who uses IEC 63086-2-1:2024:

• Air purifier and appliance manufacturers - to design, validate and compare particle-removal performance.
• Independent test laboratories and certification bodies - to produce reproducible CADR and particle-removal reports.
• Regulators and standards committees - to reference uniform test methods for product claims and possible regulatory measures.
• HVAC and indoor air quality consultants - to interpret product performance for application sizing and recommendations. Practical uses include product R&D, compliance testing, marketing claims substantiation, and comparative performance benchmarking.
