Overview

CLC IEC/FprTS 63576:2026 - Evaluation Methods for Protection Against Risk of Fire in Electric Tumble Dryers establishes guidance and test methodologies aimed at mitigating fire hazards specific to electric tumble dryers. Published by the European Committee for Electrotechnical Standardization (CLC), this technical specification is centered on addressing risks arising from lint accumulation, electric component faults, and abnormal overheating in household and similar electrical appliances. The document’s practical framework is vital for manufacturers, testing laboratories, and safety organizations seeking to enhance domestic fire protection and consumer appliance safety.

Key Topics

• Fire Risk in Electric Tumble Dryers
  The standard highlights how lint can accumulate in the enclosures of tumble dryers, potentially becoming a fuel source during electrical faults or overheating situations. Test methods are intended to assess the ability of the appliance to contain fire and prevent it from spreading outside the unit.

• Test Method Guidance
  Detailed procedures are provided for configuring tumble dryers, use of test materials, and simulating fire ignition scenarios. Directions clarify the preparation, placement, and ignition of cheesecloth surrogate lint inside and outside the appliance, as well as the necessary observational protocols and termination criteria for the test.

• Applicability to Appliance Types
  CLC IEC/FprTS 63576:2026 distinguishes between vented-type tumble dryers, heat pump tumble dryers, and addresses safety considerations for appliances using flammable refrigerants. Guidance is also included on adapting existing laboratory chambers to ensure reliably safe and reproducible testing environments.

• Test Room Environment
  The standard specifies requirements for the chamber, such as adequate volume, ventilation, humidity, temperature, visibility, and safety features to manage combustion products and provide for operator safety.

• Test Duct Requirements
  For vented tumble dryers, the specification mandates use of a standard exhaust duct or exhaust simulator, drawing on related international conventions.

Applications

• Manufacturers of Electric Tumble Dryers
  Enhance compliance and product safety by integrating these evaluation methods during appliance design, development, and testing phases.

• Testing Laboratories
  Adopt standardized approaches to assess fire containment abilities in new and existing tumble dryer models, supporting third-party certification and CE marking processes.

• Safety Assessors and Inspectors
  Apply the prescribed methodologies for market surveillance, incident investigation, and risk assessments of domestic laundry appliances.

• Regulatory and Certification Bodies
  Reference this specification to harmonize fire protection standards across electric appliances and ensure alignment with European safety directives and international standards.

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 itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
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) IEC draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). IEC takes no position concerning the evidence, validity or applicability of any claimed patent rights in
respect thereof. As of the date of publication of this document, IEC had not received notice of (a) patent(s), which
may be required to implement this document. However, implementers are cautioned that this may not represent
the latest information, which may be obtained from the patent database available at https://patents.iec.ch. IEC
shall not be held responsible for identifying any or all such patent rights.

INTRODUCTION
Electric tumble dryers are prone to the accumulation of lint within the electrical enclosure of the
appliance. Since a tumble dryer is normally not airtight, fabric fibres can pass through small air
gaps during operation. These fibres that escape the air flow path end up as accumulated lint in
the bottom sections of the enclosure. Although tumble dryers are generally designed to
minimize this, it is difficult to eliminate it completely.
The accumulated lint within the enclosure provides an additional fuel source that can increase
the severity of hazards caused by electric component faults as well as abnormal overheating
conditions. TC 61 has expressed the need to develop this Technical Specification to provide
additional evaluation methods to determine the safety of electric tumble dryers with respect to
the accumulation of lint within the enclosure.
