Foreword
This European Standard has been prepared by Technical Committee CEN/TC 246, “Natural Stone”, 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by endorsement, at the latest by May 2002, and conflicting national standards shall be withdrawn at the latest by
December 2002.
This European Standard is one of the series of 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 open
porosity.
EN 12370, Natural stone test methods - Determination of resistance to salt crystallisation.
EN 12372, Natural stone test methods - Determination of flexural strength under concentrated load.
EN 12407, Natural stone test methods – Petrographic description.
prEN 12371, Natural stone test methods - Determination of frost resistance.
prEN 13161, Natural stone test methods - Determination of flexural strength under constant moment.
prEN 13373, Natural stone test methods - Determination of geometric characteristics on units.
prEN 13755, Natural stone test methods - Determination of water absorption at atmospheric pressure.
prEN 13919, Natural stone test methods - Determination of resistance to ageing by SO action in the presence of
humidity.
prEN 14066, Natural stone test methods - Determination of thermal shock resistance.
prEN .(WI 00246011), Natural stone test methods - Determination of thermal dilatation coefficient.
prEN .(WI 00246012), Natural stone test methods - Determination of sound - speed propagation.
prEN 14157, Natural stone test methods - Determination of abrasion resistance.
prEN 14205, Natural stone test methods - Determination of Knoop hardness.
prEN 14231, Natural stone test methods - Determination of slip resistance by means of the pendulum tester.
prEN .(WI 00246018), Natural stone test methods - Determination of static elastic modulus.
prEN 14158, Natural stone test methods - Determination of rupture energy.
prEN 14147, Natural stone test methods - Determination of resistance to ageing by salt mist.
It is intended that other ENs should call up this EN 13364 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).
This European Standard has an annex A (normative).
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, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden,
Switzerland and the United Kingdom.
1 Scope
This European Standard specifies a test method to determine the breaking load at the dowel hole of natural stones
used for cladding or lining in building.
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 to 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).

3 Principle
This test consists of applying a force in a direction perpendicular to the face of a specimen through a dowel
previously placed in an hole drilled in one of its sides and measuring the breaking load of the specimen.

5 Apparatus
5.1 A balance capable of weighing the specimens with an accuracy of 0,01 % of their mass.
5.2 A ventilated oven capable of maintaining a temperature of (70 ± 5) °C.
5.3 A linear measuring device with an accuracy of 0,05 mm.
5.4 A rotary drilling machine equipped with a diamond or tungsten carbide tipped bit.
5.5 A testing machine of appropriate force in accordance with EN 12390-4 and calibrated according to this
standard.
5.6 A clamping device consisting of two metal plates having the shape and sizes shown in Figure 1.
5.7 A device for applying loads perpendicular to the axis of the dowel (see Figure 2).
5.8 A room or chamber in which the temperature of the air can be maintained at (20 ± 5) °C.
6 Preparation of the specimens
6.1 Sampling and position of bedding
The sampling is not the responsibility of the test laboratory except where specially requested.
The position of any bedding or anisotropy shall be indicated on each specimen by means of at least two parallel
lines.
6.2 Test specimens
6.2.1 General
The test can be carried out as an identification test or as a technological test.
Identification tests are tests carried out when the use of the stone with respect to the position of the planes of
anisotropy and the thickness and surface finish of the elements in the cladding are not known.
Technological tests are those carried out when the use of the stone with respect to the position of the planes of
anisotropy and the thickness and surface finish of the elements in the cladding are known. In this case the major
faces of the specimens shall have the same orientation of the face that will be loaded during use.
6.2.2 Number of specimens
The minimum number of test specimens depends on the presence of planes of anisotropy.
If the stone does not show planes of anisotropy 10 tests of Type 0 (see Figure 3) shall be made on three
specimens.
If the stone shows planes of anisotropy:
10 tests of Type I (see Figure 4) shall be made on three specimens cut parallel to the planes of anisotropy;



10 tests of Type IIa (see Figure 5) and 10 tests of Type IIb (see Figure 6) shall be made on five specimens cut
perpendicular to the planes of anisotropy.
