Scope
This European Standard specifies two methods for determining the modulus of elasticity in compression for
repair products and systems.
Method 1 is for products and systems with high creep characteristics typically those containing polymer
binders (PC).
Method 2 is for products and systems with low creep characteristics typically those containing polymer
modified (PCC) and cementitious (CC) binders.

Terms and definitions
For the purposes of this document, the terms and definitions given in EN 1504-1:2005 and EN 1504-3:2005
and the following apply.
3.1
compressive stress
compressive force carried at any time by the test specimen per unit of the original cross-section
3.2
compressive strain
ratio of the change in the distance between two reference points along the axis of the test specimen per unit
length of the onginal distance
3.3
secant modulus
ratio of stress to a corresponding strain, measured relative to a level of pre-stress applied to firmly bed the
specimen,platens and ball seating
NOTE
The secant modulus is also known as the static modulus of elasticity in compression as defined in ISO 6784.
3.4
creep
additional time-dependent strain that occurs in a test specimen under a constant applied stress
