Foreword
This document (EN 13373:2003) has been prepared by Technical Committee CEN/TC 246 "Natural stones", the
secretariat of which is held by UNI.
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by endorsement, at the latest by October 2003, and conflicting national standards shall be withdrawn at the latest
by October 2003.
This draft standard is one of the series of draft standards for tests on natural stone.
Test methods for natural stone consist of the following parts:
EN 1925, Natural stone test methods - Determination of water absorption coefficient by capillarity.
EN 1926, Natural stone test methods - Determination of compressive strength.
EN 1936, Natural stone test methods - Determination of real density and apparent density and of total and open
porosity.
EN 12370, Natural stone test methods - Determination of resistance to salt crystallisation.
EN 12371, Natural stone test methods  - Determination of frost resistance.
EN 12372, Natural stone test methods - Determination of flexural strength under concentrated load.
EN 12407, Natural stone test methods - Petrographic examination.
EN 13161, Natural stone test methods - Determination of flexural strength under constant moment.
EN 13364, Natural stone test methods - Determination of the breaking load at dowel hole.
EN 13755, Natural stone test methods - Determination of water absorption at atmospheric pressure.
EN 13919, Natural stone test methods - Determination of resistance to ageing by SO2 action in the presence of
humidity.
EN 14066, Natural stone test methods - Determination of resistance to ageing by thermal shock.
prEN 14146, Natural stone test methods - Determination of the dynamic modulus of elasticity (by measuring the
fundamental resonance frequency).
prEN 14147, Natural stone test methods - Determination of resistance to ageing by salt mist.
prEN 14157, Natural stone test methods - Determination of the abrasion resistance.
prEN 14158, Natural stone test methods - Determination of rupture energy.
prEN 14205, Natural stone test methods - Determination of Knoop hardness.
EN 14231, Natural stone test methods - Determination of the slip resistance by means of the pendulum tester.
prEN 14579, Natural stone test methods - Determination of sound speed propagation.
prEN 14580, Natural stone test methods - Determination of static elastic modulus.

It is intended that other ENs should call up this EN 13373 as the basis of evaluation of conformity. (Nevertheless it
is not intended that all natural stones products should be subjected regularly to all the listed tests. Specifications in
other standards should call up only relevant test methods).
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland,
France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal,
Slovakia, Spain, Sweden, Switzerland and the United Kingdom.

1 Scope
This European standard describes methods for verifying the geometric characteristics of products of natural stone
such as blocks, rough slabs, finished products for cladding, flooring, stairs and modular tiles. These methods are to
be applied in the case of a dispute between two parties, they are not compulsory for production control, where
simplified methods can be applied provided a correlation with the methods of this standard could be demonstrated.
2 Normative references
This European standard incorporates by dated or undated reference, provisions from other publications. These
normative references are cited at the appropriate places in the text, and the publications are listed hereafter. For
dated references, subsequent amendments or revisions of any of these publications apply to this European
Standard only when incorporated in it by amendment or revision. For undated references, the latest edition of the
publication referred to applies (including amendments).
