European foreword
This document (EN 12350-8:2019) has been prepared by Technical Committee CEN/TC 104 “Concrete
and related products”, the secretariat of which is held by SN.
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 December 2019, and conflicting national standards
shall be withdrawn at the latest by December 2019.
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 12350-8:2010.
This standard is based on the results from the EU-project “Testing-SCC” under the 5th Frame
Programme (GRD2-2000-30024/G6RD-CT-2001-00580).
Owing to its significant advantages in the improvement of construction quality and working
environment, self- compacting concrete (SCC) has been widely accepted by the construction owners.
The use of SCC in practical concrete construction is steadily increasing. Since SCC has to give
satisfactory in situ properties (perfect filling of the mould and embedment of the reinforcement,
homogeneity and full compaction) without vibration, the proper methods for testing the fresh SCC are
very important. These should address three key properties: filling ability, passing ability and resistance
to segregation. It is desirable, especially in the case of new constituents or new concrete compositions,
to test the consistence of fresh SCC before casting in place.
A number of test methods including this test are available for testing fresh SCC. Most of the commonly
used test methods were evaluated in the recently closed EU-project “Testing-SCC” under the 5th Frame
Programme (GRD2-2000-30024/G6RD-CT-2001-00580). According to the results from this EU project,
it seems no single test method can completely cover all three key properties. Nevertheless any test
method should at least be correlated to the practical situation and give consistent results in order to
provide reliable data for judgment of concrete workability.
This standard is one of a series on testing concrete.
EN 12350, Testing fresh concrete, consists of the following parts:
— Part 1: Sampling and common apparatus
— Part 2: Slump test
— Part 3: Vebe test
— Part 4: Degree of compactability
— Part 5: Flow table test
— Part 6: Density
— Part 7: Air content – Pressure methods
— Part 8: Self-compacting concrete – Slump-flow test
— Part 9: Self-compacting concrete – V-funnel test
— Part 10: Self-compacting concrete – L-box test
— Part 11: Self-compacting concrete – Sieve segregation test
— Part 12: Self-compacting concrete – J-ring test
The following amendments have been made to the 2010 edition of this standard:
a) reference to common apparatus and specification given in EN 12350-1;
b) reference and procedure for slump-flow retention testing;
c) option to include specified slump-flow class or slump-flow target value in report.
According to the CEN-CENELEC Internal Regulations, the national standards organisations of the
following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria,
Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland,
Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Republic of
North Macedonia, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the
United Kingdom.
