Overview

EN 60695-11-2:2017 (IEC 60695-11-2:2017 RLV) specifies the apparatus, production methods and confirmatory test arrangement for a nominal 1 kW propane/air pre‑mixed test flame used in fire hazard testing. Classified as a basic safety publication (IEC Guide 104 / ISO/IEC Guide 51), this third edition replaces the 2013 edition and introduces an alternative method for producing the test flame. The standard is intended primarily for technical committees developing standards and provides guidance on generating and confirming a standardized 1 kW test flame for use in ignitability and fire‑hazard evaluations.

Key Topics

• Purpose and scope: Requirements for production and confirmation of a standardized 1 kW pre‑mixed flame (propane/air) for fire hazard testing.
• Apparatus details: Construction and arrangement of the burner, fuel supply and flow control, copper block reference, thermocouple placement, and recording devices.
• Production methods: Two production options (Method A and Method B - the latter added as an alternative in this edition) for establishing the 1 kW pre‑mixed flame.
• Confirmatory test arrangement: Principle, procedure and recommended frequency for confirmatory testing to ensure the effective power output of the flame matches the nominal 1 kW.
• Laboratory requirements: Guidance on laboratory fumehoods or chambers and safe operation considerations when producing and measuring the test flame.
• Normative annex: Detailed burner drawings, gas supply arrangements, copper block specifications and example confirmatory test setups are provided in Annex A.

Applications

• Standardizes a 1 kW test flame used as a reproducible ignition source in:
  • Development and validation of fire hazard test methods.
  • Inter‑laboratory comparisons and round‑robin testing.
  • Guidance for drafting component and product standards that address ignitability from a small pre‑mixed flame.
• Primary users:
  • Standards committees and technical working groups developing electrotechnical and safety standards.
  • Test method developers and research laboratories conducting fire hazard method development.
• Note: The standard is not intended as a certification or manufacturer procedure; it is guidance for standardization and method formulation.

Related Standards

• IEC 60695-1-10 / IEC 60695-1-11 - Guidance on fire risk and ignition prevention for electrotechnical products.
• IEC TS 60695-11-40 - Guidance on confirmatory tests for test flames.
• Other parts of the IEC 60695 Part 11 series cover 500 W, 50 W and needle‑flame methods for complementary test flame specifications.

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.

INTRODUCTION
In the design of any electrotechnical product, the risk of fire and the potential hazards
associated with fire need to be considered. In this respect the objective of component, circuit,
and product design, as well as the choice of materials, is to reduce to acceptable levels the
potential risks of fire during normal operating conditions, reasonable foreseeable abnormal
use, malfunction, and/or failure. The IEC has developed IEC 60695-1-10 [1] , together with its
companion, IEC 60695-1-11 [2], to provide guidance on how this is to be accomplished.
The primary aims of IEC 60695-1-10 and IEC 60695-1-11 are to provide guidance on how:
a) to prevent ignition caused by an electrically energized component part, and
b) to confine any resulting fire within the bounds of the enclosure of the electrotechnical
product in the event of ignition.
Secondary aims of these documents include the minimization of any flame spread beyond the
product’s enclosure and the minimization of harmful effects of fire effluents such as heat,
smoke, toxicity and/or corrosivity.
Fires involving electrotechnical products can also be initiated from external non-electrical
sources. Considerations of
