European foreword
This document (EN 993-5:2018) has been prepared by Technical Committee CEN/TC 187 “Refractory
products and materials”, the secretariat of which is held by BSI.
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 2019, and conflicting national standards shall be
withdrawn at the latest by June 2019.
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 993-5:1998.
Reproducibility and repeatability data are available only for a limited number of testing methods and
materials, but may be complemented in subsequent edition.

1 Scope
This document specifies a method of determination of the cold crushing strength of dense shaped
refractory products.
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.
ISO 13385-1, Geometrical product specifications (GPS) — Dimensional measuring equipment — Part 1:
Callipers; Design and metrological characteristics
ISO 5022, Shaped refractory products — Sampling and acceptance testing
3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
ISO and IEC maintain terminological databases for use in standardization at the following addresses:
• IEC Electropedia: available at http://www.electropedia.org/
• ISO Online browsing platform: available at http://www.iso.org/obp
3.1
cold crushing strength
maximum load per unit area, applied under specified conditions at room temperature, that a refractory
product will withstand before failure occurs
3.2
dense shaped refractory product
product with specific dimensions, having a true porosity of less than 45 % by volume, when measured
in accordance with EN 993-1
3.3
sample
representative collection of items that can be obtained by sampling in accordance with ISO 5022
3.4
item
refractory brick or shape
3.5
test piece
piece of material extracted from an item (3.4) and suitably shaped and prepared for the test
4 Principle
A test piece of known dimensions is subjected under specified conditions to a steadily increasing
compressive load until its failure, when it cannot support a further increase in load. The cold crushing
strength is calculated from the maximum load indicated at failure and the mean cross-sectional area
over which the load is applied.
