This European Standard was approved by CEN on 1 July 2019.

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 16074:2019) has been prepared by Technical Committee CEN/TC 139 “Paints and
varnishes”, the secretariat of which is held by DIN.
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 March 2020, and conflicting national standards shall
be withdrawn at the latest by March 2020.
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.
This document supersedes EN 16074:2011.
The main changes compared to EN 16074:2011 are:
a) the symbols have been aligned with current standards [ISO 3251 and ISO 3233 (all parts)], i.e. m for
mass, s for spreading rate, NV for non-volatile matter and ρ for density;
b) Clause 8 on "Determination of the density" has been added;
c) the text has been editorially revised and the normative references have been updated.
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, France, Germany, Greece, Hungary, Iceland,
Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Republic of
North Macedonia, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the
United Kingdom.
1 Scope
The method specifies the gravimetric procedure for determining the non-volatile-matter content as a
percentage by mass of the majority of thermally cured coil coatings and subsequently for determining
the theoretical spreading rate. The method is not suitable for pure epoxy coil coatings.
2 Normative references
The following documents are referred to in the text in such a way that some or all of their content
constitutes requirements 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.

3 Terms and definitions
For the purposes of this document, the terms and definitions given in EN 13523-0 and the following
apply.
ISO and IEC maintain terminological databases for use in standardization at the following addresses:
— IEC Electropedia: available at http://www.electropedia.org/

3.1
spreading rate
surface area that can be covered by a given quantity of coating material to give a dried film of requisite
thickness
2 2
Note 1 to entry: It is expressed in m /l or m /kg.
Note 2 to entry: See also theoretical spreading rate.
[SOURCE: EN ISO 4618:2014, 2.238, modified – Application rate and practical spreading rate were
deleted in Note 2.]
3.2
non-volatile matter
NV
residue by mass obtained by evaporation under specified conditions
Note 1 to entry: Instead of the term “non-volatile matter” different terms, such as solid, dry residue, dry matter,
solid matter, stoving residue are being used commonly with the respective abbreviations. The term “non-volatile
matter” which is also applied in ISO 3251 should be used together with the abbreviation “NV” instead of these
terms.
[SOURCE: EN ISO 4618:2014, 2.176]
3.3
theoretical spreading rate
spreading rate calculated solely from the volume of non-volatile matter
[SOURCE: ISO 4618:2014, 2.256]
4 Principle
The non-volatile-matter content determination is based on the mass of dry residue of a known quantity
of wet paint cured in a pan or applied on a metal panel. Th
