METHOD FOR MEASURING PERFORMANCE OF PORTABLE

HOUSEHOLD ELECTRIC ROOM AIR CLEANERS

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
A PAS is a technical specification not fulfilling the requirements for a standard, but made
available to the public.
IEC-PAS 62587 has been prepared by the Association of Home Appliance Manufacturers
(AHAM) and processed by IEC technical committee 59: Performance of household and similar
electrical appliances. It is based on ANSI/AHAM AC-1-2006
The text of this PAS is based on the This PAS was approved for
following document: publication by the P-members of the
committee concerned as indicated in
the following document
Draft PAS Report on voting
59/499/PAS 59/506/RVD
Following publication of this PAS, which is a pre-standard publication, the technical committee
or subcommittee concerned will transform it into an International Standard.
This PAS shall remain valid for an initial maximum period of 3 years starting from the
publication date. The validity may be extended for a single 3-year period, following which it
shall be revised to become another type of normative document, or shall be withdrawn.

INTRODUCTION
This Publicly Available Specification (PAS) contains test procedures for measuring the

relative reduction by the air cleaner of particulate matter suspended in the air in a specified

test chamber. It also prescribes a method for measuring the operating power and standby

power of the air cleaner. The test procedures may be applied to any brand or model of

portable household electric room air cleaners within the stated confines of the standard's

limits of measurability for measuring performance

The annexes to this PAS are included for informative purposes only unless the annexes are

noted as normative.
This PAS may involve hazardous materials, operations, and equipment. This PAS does not
purport to address all of the safety problems associated with its use. It is the responsibility of
whoever uses this PAS to consult and establish appropriate safety and health practices and
determine the applicability of any regulatory limitations prior to use.

METHOD FOR MEASURING PERFORMANCE OF PORTABLE

HOUSEHOLD ELECTRIC ROOM AIR CLEANERS

1 Scope and object
This Publicly Available Specification establishes a system of uniform, repeatable procedures

and standard methods for measuring specified product characteristics of portable household

electric room air cleaners.
The standard methods provide a means to compare and evaluate different brands of portable

household electric room air cleaners regarding characteristics significant to product use.
The standard methods of measurement are not intended to inhibit improvement and
innovation in product testing, design or performance.
This standard method applies to portable household electric room air cleaners as defined in
Clause 3.
This standard method includes definitions and safety characteristics of portable household
electric room air cleaners of the types indicated.
This standard method measures the relative reduction by the air cleaner of particulate matter
suspended in the air in a specified test chamber. It also prescribes a method for measuring
the operating power and standby power of the air cleaner.
This standard method has defined limits of measurability based on the statistical accuracy of
the methods. Based on a 95 % confidence limit (2 standard deviations), a clean air delivery
rate (CADR) (see 3.5) cannot be distinguished between zero (0) and a CADR rating less than
those CADR limits shown below. Therefore, this PAS only applies to air cleaners with
minimum CADR ratings of:
Dust CADR = 10 cfm
Cigarette smoke CADR = 10 cfm
Pollen CADR = 25 cfm
The maximum CADR values are determined based on theoretical maximum limits. The
theoretical maximum limits are determined by the maximum number of initial available
particles, the acceptable minimum number of available particles, an average background
natural decay rate (from statistical study), the size of the chamber, and the available minimum
experiment time. CADR values greater than those listed will not have the necessary statistical
data required by this method. Therefore, the document only applies to air cleaners with
maximum CADR ratings of:
Dust CADR = 400 cfm
Cigarette smoke CADR = 450 cfm
Pollen CADR = 450 cfm
The precision of this document as based on a 0 CADR air cleaner expressed as 2 standard
deviation limits (95 %) are:
Dust CADR = ± 10 cfm
Cigarette Smoke CADR = ± 10 cfm
Pollen CADR = ± 25 cfm
