This European Standard was approved by CEN on 3 June 2005.

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 Central Secretariat 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 Central Secretariat has the same status as the official
versions.

CEN members are the national standards bodies of Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France,
Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia,

Foreword
This European Standard (EN 679:2005) has been prepared by Technical Committee CEN/TC 177
“Prefabricated reinforced components of autoclaved aerated concrete or light-weight aggregate concrete with
open structure”, 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text or by endorsement, at the latest by January 2006, and conflicting national standards shall be withdrawn at
the latest by January 2006.
This document supersedes EN 679:1993.
In order to meet the performance requirements as laid down in the product standard for prefabricated
components of autoclaved aerated concrete, a number of standardized test methods are necessary.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic,
Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania,
Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden, Switzerland
and United Kingdom.

1 Scope
This European Standard specifies the procedure for the determination of the compressive strength of
autoclaved aerated concrete.
2 Normative references
The following referenced documents are indispensable for the application 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.
EN 678, Determination of the dry density of autoclaved aerated concrete
EN 1353, Determination of moisture content of autoclaved aerated concrete
EN 12390-4, Testing hardened concrete — Part 4: Compressive strength — Specification for testing machines
3 Principle
The compressive strength is determined on test specimens as the ratio between the rupture load in axial
compression and the cross-sectional area of the test specimen perpendicular to the loading direction.
4 Apparatus
a) saw for cutting test specimens;
b) compression testing machine, which meets the requirements of EN 12390-4, machine class 1 or 2;
c) calipers, capable of reading the dimensions of the test specimens to an accuracy of 0,1 mm;
d) ventilated drying oven, capable of maintaining a temperature of (105 ± 5) °C;
e) straight edge, at least 200 mm long, a 0,1 mm-feeler gauge, a 1 mm-feeler gauge, and a square;
f) balance, capable o
