Introduction
The requirements for testing machines set out in this document have been formulated to satisfy the
needs of those compressive tests on concrete specimens which are specified in EN 206:2013+A1:2016.
Machines conforming to this standard can be suitable for other uses, but this needs to be carefully
considered on an individual test basis. Particular care needs to be taken before using machines
conforming to this document for compressive tests on small specimens, e.g. those with lateral
dimensions significantly less than 100 mm. The main concern is that the ball-seating fitted to the upper
platen can be too large to align satisfactorily on the top of such small specimens and special adaptations
can be required. Another concern is the ability to accurately determine the failure load of small or low
strength specimens.

square platen, or the diameter of a circular platen, shall not be less than the designated size of the
specimen.
4.1.6 The two contact faces of an auxiliary platen shall be parallel to a tolerance of 0,05 mm.
4.1.7 Auxiliary platens shall be at least 23 mm thick.
4.1.8 Spacing blocks may be used if there is a requirement to reduce the distance between the

— dials or digital displays which allow the force to be read to the accuracy specified in 4.2.2;
— a system which allows the maximum force sustained to be read after completion of the test, until
reset;
— displays readable from the operating position.
The machine force indication system shall not be affected by explosive failure of the specimen.
The lowest verifiable value of each measuring range shall be less than or equal to 20 % of the maximum

shall apply to each range.
4.2.2 Force indicator accuracy
For machines built after the publication of the first edition of this standard (year 2000), the required
