European foreword

This document (EN 1097-7:2022) has been prepared by Technical Committee CEN/TC 154 “Aggregates”,

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 April 2023, and conflicting national standards shall be

withdrawn at the latest by April 2023.

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 1097-7:2008.

This document has been prepared under a Standardization Request given to CEN by the European

Commission and the European Free Trade Association.

In comparison with the previous edition EN 1097-7:2008, the following technical modifications have

been made:

a) in the Scope, a reference to methods for determination of particle density of aggregates has been

added;

b) Clause 3 “Terms and definitions” has been clarified to correspond with definitions in EN 1097-6. The

definition of size fraction d /D has been added;
i i

c) in Clause 5 “Materials”, low viscosity white mineral oils have been added among the examples of

suitable liquids given in the note;

d) in 6.3, the required accuracy of the water bath temperature has been reduced from (25,0 ± 0,1) °C to

either (25,0 ± 3,0) °C or (25,0 ± 0,5) °C depending on the liquid used. Texts in Clause 8, A.2.5 and B.2.4

have been revised accordingly;

e) the required accuracy of the balance for the pyknometer volume determination has been reduced

from 0,000 1 g to 0,001 g, since water is always used for this purpose. The texts in 6.4, 6.5 and A.2.2

have been revised accordingly;

f) in Clauses 7 and 8, the required masses of the test portion and the test specimens have been revised.

The possibility to vary the filler amount, and thus the ratio of filler and liquid, has been added in

order to reduce the influence of the temperature on the density of the pyknometer liquid;

g) the required number of test specimens has been reduced from three to two, provided that the two

test results differ less than 0,025 Mg/m . The texts in Clauses 7, 8 and 9 have been revised

accordingly;

h) in Clause 8 “Procedure”, the note about adding liquid carefully has been transformed into main text;

i) in Clause 10 “Test report”, the density of the liquid used for the determination is moved from

Required data to Optional data;

j) the title of Annex A has been revised to “Determination of the pyknometer volume” since calibration

was not the correct term. All texts referring to calibration have been corrected accordingly. A new

paragraph (A.2.4) has been added to describe the evacuation of the pyknometer by means of vacuum;

---------------------- Page: 5 ----------------------
SIST EN 1097-7:2023
EN 1097-7:2022 (E)

k) the title of Annex B has been shortened and B.1 has been clarified regarding the use of Annex B;

l) Annex C has been removed since the precision data given cannot be tracked down any longer.

Consequently, the note about precision statement in Clause 9 has been revised;

m) in the Bibliography, EN 1097-6 and EN 1936 have been added and the national standards have been

deleted.

In addition, the whole document has been updated and the “Principle”, “Preparation of test portion”,

“Procedure” and Annex A have been clarified.
