This European Standard was approved by CEN on 10 March 2011.

CEN members are bound to comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European
Standard the status of a national standard without any alteration. Up-to-date lists and bibliographical references concerning such national
standards may be obtained on application to the CEN-CENELEC Management Centre or to any CEN member.

This European Standard exists in three official versions (English, French, German). A version in any other language made by translation
under the responsibility of a CEN member into its own language and notified to the CEN-CENELEC Management Centre has the same
status as the official versions.

Foreword
This document (EN 3844-1:2011) has been prepared by the Aerospace and Defence Industries Association of
Europe - Standardization (ASD-STAN).
After enquiries and votes carried out in accordance with the rules of this Association, this Standard has received
the approval of the National Associations and the Official Services of the member countries of ASD, prior to its
presentation to CEN.
This European Standard shall be given the status of a national standard, either by publication of an identical text or
by endorsement, at the latest by May 2012, and conflicting national standards shall be withdrawn at the latest by
May 2012.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights.
CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech
Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania,
Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden,
Switzerland and the United Kingdom.
1 Scope
This European Standard specifies the test method for the determination of the vertical flame propagation and after
flame time of non metallic materials.
This test method is also used for testing non metallic materials which have to meet the test criteria for the vertical
Bunsen burner test:
 with a flame application time of 60 s;
 with a flame application time of 12 s.
It is used for evaluation of non metallic materials or constructions used in the interiors of aerospace vehicles but
may be used in other applications as specified in applicable procurement and regulatory documents.
This standard should be used to measure and describe the properties of non metallic materials, products or
assemblies in response to heat and flame under controlled laboratory conditions and should not be used to
describe or appraise the fire hazard or fire risk of materials, products, or assemblies under actual fire conditions.
However, results of this test may be used as elements of a fire risk assessment which takes into account all of the
factors which are pertinent to an assessment of the fire hazard of a particular end use.
2 Normative references
The following referenced documents are indispensable for the application of this document. For dated references,
only the edition cited applies. For undated references, the latest edition of the referenced document (including any
amendments) applies.
1)
ASTM-D 5025, A laboratory burner used for small-scale burning test on plastic materials
3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
time of flame application
length of time for which the burner flame is applied to the specimen
3.2
after flame time
time in seconds for which the specimen continues to flame after the burner flame has been removed from the
specimen
3.3
after flame time of drips
time in seconds that any flaming material continues to flame after falling from the specimen to the bottom of the
chamber
1) Published by: ASTM National (US) American Society for Testing and Materials http://www.astm.org/.
3.4
burn length
distance in millimetres from the original specimen edge to the farthest evidence of damage of the test specimen
due to that area's combustion, including areas of partial consumption, charring, or embrittlement, but not including
areas sooted, stained, warped or discoloured, nor areas where material has shrunk or melted away from the heat
4 Principle of method
Testing is performed on a specimen that is held vertical. A burner flame, having defined parameters, is applied to
the specimen for a defined period of time. The after flame time and the burn length is measured. The occurrence of
drips and their after flame time is measured.
