This document specifies a method to evaluate the capability of portable household air cleaners to reduce the concentration and viability of key experimentally generated bioaerosols in a specified chamber. Indoor air free of harmful microbes is important to the health of occupants. This is particularly relevant with regard to increased time spent indoors. Air cleaners are used to reduce the concentrations of microorganisms in indoor air. The efficiency of such air cleaners to reduce airborne microorganisms can be assessed in test chambers at controlled air temperature and relative air humidity. The test is applicable to portable air cleaners commonly used in single room spaces such as those based on mechanical filtration, ultraviolet (UV), ionizers, photocatalytic oxidation, and ozone generators in-unit technology. If the air cleaner does not claim to have the function of reducing microorganisms, this document may not be applicable unless it is being used to simply evaluate the performance. This document deals with measurement procedures regarding the reduction of the microbial contamination related to electrical air cleaner appliances for household and similar use. This document does not apply to appliances intended to be used in medical, veterinary, or pharmaceutical applications. This document does not address sanitization, disinfection, or sterilization measures. This document does not support, by itself any health-related claims or conclusions about prevention or treatment of a disease or health improvement. NOTE 1 IEC 63086-3-1 is created for household and similar electrical air cleaners and is not intended to conflict with or replace standards for commercial or industrial consumers. NOTE 2 In this document, we do not suggest performance test methods that measure the by-products of either the interaction between microbes or between the air cleaner and the microbes tested in this document. The formation of by-products is an important subject. The subject of measuring by-products is under study, and AHAM will address this in future documents. NOTE 3 This document does not apply to appliances intended for use in medical treatment locations, such as surgical suites, laboratories, medical treatment rooms, etc.

This document describes a procedure for measuring the performance of general ventilation air cleaning
devices in their end use installed configuration. The performance measurements include removal
efficiency by particle size and the resistance to airflow. The test procedures include the definition and
reporting of the system airflow.
The procedure describes a method of counting ambient air particles of 0,3 μm to 5,0 μm upstream and
downstream of the in-place air cleaner(s) in a functioning air handling system. The procedure describes
the reduction of particle counter data to calculate removal efficiency by particle size.
Since filter installations vary dramatically in design and shape, a protocol for evaluating the suitability
of a site for filter evaluation and for system evaluation is included. When the evaluated site conditions
meet the minimum criteria established for system evaluation, the performance evaluation of the system
can also be performed according to this procedure.
This document also describes performance specifications for the testing equipment and defines
procedures for calculating and reporting the results. This document is not intended for measuring
performance of portable or movable room air cleaners or for evaluation of filter installations with an
expected filtration efficiency at or above 99 % or at or below 30 % when measured at 0,4 μm.

Their maximum rated voltage being not more than 300 V for single phase appliances and 600 V for multi-phase appliances. Appliances not intended for normal household use but which nevertheless can be a source of danger to the public, such as appliances intended to be used by laymen in shops, in light industry and on farms, are within the scope of this standard. The appliances referenced above can consist of one or more factory-made assemblies. If provided in more than one assembly, the separate assemblies are used together, and the requirements are based on the use of matched assemblies. This document does not take into account refrigerants other than group A1, A2L, A2 and A3 as defined by ISO 817. Flammable refrigerants are limited to those of a molar mass of more than or equal to 42 kg/kmol based on WCF (worst case formulation) as specified in ISO 817. As far as practical, this document deals with common hazards presented by appliances that are encountered in normal use and assumes that installation, servicing, decommissioning, and disposal are safely handled by competent persons and accidental release of refrigerants is avoided. However, it does not prescribe the criteria to ensure competence of persons during installation, servicing and disposal. Safety requirements during disposal are not specified in this standard. Supplementary heaters, or a provision for their separate installation, are within the scope of this standard, but only heaters which are designed as a part of the appliance package, the controls being incorporated in the appliance. Attention is drawn to the fact that
- for appliances intended to be used in vehicles or on-board ships or aircraft, additional requirements can be necessary;
- in many countries, additional requirements are specified, for example, by the national health authorities responsible for the protection of labour and the national authorities responsible for storage, transportation, building constructions and installations.
This document does not apply to
- humidifiers intended for use with heating and cooling equipment (IEC 60335-2-88);
- appliances designed exclusively for industrial processing;
- appliances intended to be used in locations where special conditions prevail, such as the presence of a corrosive or explosive atmosphere (dust, vapour or gas).
This seventh edition cancels and replaces the sixth edition published in 2018. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
- Clause 1: added thermoelectric heat pumps to the scope and increased maximum rated voltage to 300 V for single phase appliances;
- Clause 7: revised requirements for marking on the appliance and packaging, including a symbol for minimum floor area and modifying the symbol for flammable refrigerants to include the safety group per ISO 817;

This document deals with the likely degradation of air performance of fans tested in standardized airways in accordance with ISO 5801 when compared with the performance of fans tested under actual site conditions. It deals with the performance of a number of generic types of fan and fittings. The results given are intended as guidelines and only provide trends, as the system effect depends on the exact geometry of the fan and disturbing component. The test data presented in this document are taken from an extensive experimental program conducted 20 years ago by NEL (National Engineering Laboratory, UK), mainly on axial and centrifugal fans. Data are also taken from several research projects financially supported by ASHRAE, some of them being carried out in the AMCA laboratory in Chicago, as well as from results published previously by individual fan manufacturers.

1.1   This European Standard specifies the constructional requirements for fans constructed to Group II G (of explosion groups IIA, IIB and hydrogen) categories 1, 2 and 3, and Group II D categories 2 and 3, intended for use in explosive atmospheres.
NOTE 1   Operation conditions for the different categories of fans used in this European Standard are defined in Clause 4.
NOTE 2   Technical requirements for category 1 D fans are not given in this document. Where explosive dust atmospheres are regularly conveyed, explosion protection measures as described in EN 1127–1 are required if this specific us is needed.
1.2   This European Standard does not apply to group I fans (fans for mining), cooling fans or impellers on rotating electrical machines, cooling fans or impellers on internal combustion engines.
NOTE 1   Requirements for group I fans are given in EN 1710.
NOTE 2   The requirements for electrical parts are covered by references to electrical equipment standards.
1.3   This European Standard specifies requirements for design, construction, testing and marking of complete fan units intended for use in potentially explosive atmospheres in air containing gas, vapour, mist and/or dusts. Such atmospheres may exist inside (the conveyed atmosphere (flammable or not)), outside, or inside and outside of the fan.
1.4   This European Standard is applicable to fans working in ambient atmospheres and with normal atmospheric conditions at the inlet, having
-   absolute pressures ranging from 0,8 bar to 1,1 bar,
-   and temperatures ranging from −20 °C to +60 °C,
-   and maximum volume fraction of 21 % oxygen content,
-   and an aerodynamic energy increase of less than 25 kJ/kg.
NOTE 1   25 kJ/kg is equivalent to 30 kPa at inlet density of 1,2 kg/m3.
This European Standard may also be helpful for the design, construction, testing and marking of fans intended for use in atmospheres outside the validity range stated above or in cases where other material pairings need to be used. In this case, the ignition risk assessment, ignition protection provided, additional testing (if necessary), manufacturer's marking, technical documentation and instructions to the user, should clearly demonstrate and indicate the equipment's suitability for the conditions the fan may encounter.
This European Standard should not apply to integral fans as a part of Diesel engines, vehicles or electric motors.
NOTE 2   Where undated references are used in the body of the standard the latest edition applies.
