Part 11-4: Test flames – 50 W flame –
Apparatus and confirmational test method


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) 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.
International Standard IEC 60695-11-4 has been prepared by IEC technical committee 89: Fire
hazard testing.
This first edition of IEC 60695-11-4 cancels and replaces the second edition of technical
specification IEC/TS 60695-11-4 published in 2004. It constitutes a technical revision and now
has the status of an International Standard.
It has the status of a basic safety publication in accordance with IEC Guide 104 and ISO/IEC
Guide 51.
The main changes with respect to the previous edition are the integration of minor editorial and
technical changes throughout the text.

arrangement and guidance
Part 11-3: Test flames – 500 W flames – Apparatus and confirmational test methods
Part 11-4: Test flames – 50 W flame – Apparatus and confirmational test method
Part 11-5: Test flames – Needle-flame test method – Apparatus, confirmatory test

INTRODUCTION
The best method for testing electrotechnical products with regard to fire hazard is to duplicate
exactly the conditions occurring in practice. In most instances, this is not possible. Accordingly,
for practical reasons, the testing of electrotechnical products with regard to fire hazard is best
conducted by simulating as closely as possible the actual effects occurring in practice.
Work initiated by ACOS resulted in a series of standards that make available standardized test
flames covering a range of powers for the use of all product committees needing such test
flames. A needle flame is described in IEC 60695-11-5, two 500 W flames are described in
IEC 60695-11-4, and a 1 kW flame is described in IEC 60695-11-2.
This international standard provides a description of the apparatus required to produce a 50 W
test flame and a description of a calibration procedure to check that the test flame produced
meets given requirements. Guidance on confirmatory tests for test flames is given in
IEC 60695-11-40.
Three 50 W test flame methods (A, B and C) were originally specified in
IEC/TS 60695-11-4:2000, with the intention that users would determine a ranking preference.
This process has resulted in two of these flame methods being withdrawn, as shown below:

50 W test flame method Flame type Gas Approximate flame height / mm
A Pre-mixed Methane 20
B Withdrawn
C Withdrawn

The method described in Clause 4 of this standard is the method that was originally designated
as Method A. It produces a 50 W nominal test flame using a single gas supply tube, a needle
valve to adjust the gas back pressure, a flowmeter to adjust the gas flow rate, and adjustable
air ports on the burner tube.
The flame is produced by burning methane, and the method makes use of a more tightly
specified version of a burner that was used in some countries for many years.
The method has been developed as a technical enhancement of previous technology.
