Foreword
This document (EN 16245-2:2013) has been prepared by Technical Committee CEN/TC 249 “Plastics”, the
secretariat of which is held by NBN.
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text or by endorsement, at the latest by November 2013, and conflicting national standards shall be withdrawn
at the latest by November 2013.
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.
EN 16245 consists of the following parts, under the general title Fibre-reinforced plastic composites —
Declaration of raw material characteristics:
 Part 1: General requirements
 Part 2: Specific requirements for resin, curing systems, additives and modifiers (the present document)
 Part 3: Specific requirements for fibre
 Part 4: Specific requirements for fabrics
 Part 5: Specific requirements for core materials
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, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom.
1 Scope
This European Standard specifies the minimum information to be declared for resins, curing systems,
additives and modifiers to be used for the manufacturing of composites products.
These specific declaration requirements are in addition to the general requirements given in EN 16245-1.
This document includes requirements for the Certificate of Analysis (CoA). The purpose of the CoA is to verify
that material properties and quality conforms to the declared values.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
accelerator
promoter
substance used in small proportion to increase the reaction rate of a chemical system (reactants, plus other
additives)
[SOURCE: EN ISO 472:2013, 2.1]
3.2
additive
modifier
substance added to a resin to improve or modify one or more properties (i.e. UV stability, surface tensions, air
