This document is currently submitted to CEN Enquiry.
This document will supersede EN 1097-7:2008.

In comparison with the previous edition, the following technical modifications have been made:

a) Precision of the water bath temperature has been revised from (25,0 ± 0,1) °C to (25,0 ± 3,0)

°C or (25,0 ± 0,5) °C depending on the liquid used. As a consequence, texts in Clauses 6.3, 8,

A.2.4 and B.2.4 have been revised.

b) In the Scope, a reference to methods for determination of particle density of aggregates has

been added.

c) The “European foreword”, “Normative references”, “Terms and definitions” and “Test report”

clauses are updated.

d) Terms and definitions have been clarified to correspond with definitions in EN 1097-6.

e) The “Principle”, “Preparation of test portion” and “Procedure” clauses have been clarified.

f) In the “Materials” clause, low viscosity white mineral oils have been added among the

examples given in the note.

g) In “Procedure”, the note about adding liquid carefully has been transformed into main text.

h) In the Bibliography, EN 1097-6 has been added.

In this document, the Annexes A and B are normative and the Annex C is informative.
