European foreword
This document (EN 6064:2017) 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 June 2018 and conflicting national standards shall be
withdrawn at the latest by June 2018.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN 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, 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.
Scope
This test method defines the procedure for the estimation of the extent of cure of certain non-metallic
materials (e.g. preimpregnated and neat resin systems, adhesives) for aerospace use. The extent of cure
is estimated by Differential Scanning Calorimetry (DSC) measurements of uncured (reference) and cured
materials. Additional evidence on the extent of cure may be gained by combining results from this method
with those obtained by other techniques.
This standard does not give any directions necessary to meet the health and safety requirements. It is the
responsibility of the user of this standard to adopt appropriate health and safety precautions.
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.

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 1)
θ is the heating rate, in degrees Celsius or Kelvin by minutes;
∆H is the reaction enthalpy, in Joules by grams;
∆H is the reaction enthalpy corrected to 100 % resin content, in Joules by grams;
A-curve is the reference reaction curve for uncured material;
B-curve is the reaction curve for an already (semi-) cured sample.
3.2
calibration (see 6.6)
T is the melting temperature, in degrees Celsius or Kelvin
m
∆H is the enthalpy of fusion, in Joules by grams

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.
