This European Standard was approved by CEN on 28 August 2017.

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.

European foreword
This document (EN 6041:2018) 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 July 2018, and conflicting national standards shall be
withdrawn at the latest by July 2018.
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 organisations of the
following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria,
Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia,
France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta,
Netherlands, Norway, Poland, Portugal, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland,
Turkey and the United Kingdom.
1 Scope
This test method defines the procedure for the determination of the curing-characteristic and glass
transition temperature of non-metallic materials (e.g. preimpregnated and neat resin systems,
adhesives) for aerospace use by Differential Scanning Calorimetry (DSC).
The results obtained by this method may be useful for:
 derivation of the optimum cure cycle (only together with other test methods e.g. Tg determination)
 assessment of the condition of the resin
 assessment of the ageing behavior of the resin
This European Standard does not give any directions necessary to meet the health and safety
requirements. It is the responsibility of the user of this European Standard to adopt appropriate health
and safety precautions.
2 Normative references
The following documents, in whole or in part, are normatively referenced in this document and are
indispensable for its application. For dated references, only the edition cited applies. For undated
references, the latest edition of the referenced document (including any amendments) applies.

3 Symbols and definitions
For the purposes of this document, the following symbols and definitions apply.
The determination of these parameters shall be agreed upon between manufacturer and purchaser in
case of non-ideal curves or different instrument types.
3.1
curing reaction (see Figure 3)
θ is the heating rate, in °C /min or °K /min;
T is the onset temperature, in °C or °K;
os
T is the peak maximum temperature, in °C or °K;
p
∆H is the reaction enthalpy, in J/g;
∆H is the reaction enthalpy corrected to 100 % resin content, in J/g.
3.2
calibration (see 6.5)
T is the melting temperature, in °C or °K;
m
∆H is the enthalpy of fusion, in J/g.
m
3.3
glass transition (see Figure 2)
Tg is the onset temperature of transition, in °C or °K;
os
Tg is the end temperature of transition, in degrees °C or °K;
e
Tg is the glass transition temperature, in degrees °C or °K.
4 Principle of the method
Differential Scanning Calorimetry (DSC) measures the temperatures and the heat flow associated with
transitions in materials as a function of time and temperature.
