NOTE The permitted methods of specimen manufacture realise different specimen shapes and density, and thus for
the same mixture, different strengths. Hence it is important, on the basis of experience and utilisation, not to separate
strength from the method of specimen manufacture.

The age of classification and curing conditions shall be specified in accordance with practice at the place of
use.

For characterisation or mixture design testing in the laboratory, compressive strength shall be the average
result from at least three specimens. lf one value varies by more than 20 % of the average, it shall be

production control to ensure that the requirements of the quality manual are implemented and maintained.

8.3.3 lnternal audits

The manufacturer should carry out internal quality audits to verify compliance with the planned arrangements
and the effectiveness of the quality system. Audits should be scheduled on the basis of the status and
importance of the activity. The audits and follow up action should be carried out in accordance with
documented procedures. The results of the audits should be documented and brought to the attention of the

24
 EN 14227-1:2013 (E)

0 instructions so that the mixture is identifiable up to the point of delivery as regards source and type

8.4.2 Gomposition of the mixture

The composition of the mixtures should be established from a laboratory mixture design procedure intended to
ensure the mixture should have properties conforming to the relevant standard.

Where applicable, the composition of regularly produced mixtures will be included in a catalogue of mixtures
compositions and considered as the mixture base line or target composition.

The compositions should be re-established in case of significant change in constituents and should be
a
reviewed periodically to ensure the mixture conforms to requirements taking into account any change in
properties of constituents.

B.4.3 Constituents o
@
Documentation should detail the source and type of each constituent of the mixture for use at the production
N
location. o
N
J$
Adequate supplies of constituent should be available to ensure that the planned rates of production and
delivery can be maintained. o
z
The specifications for incoming constituents should be established and communicated to suppliers by means
o
of written orders. o
o
{o)
The control procedures should check that constituents are capable of providing the required quality. o
o
O
(rl
Constituents should be transported and stored in such a manner as to avoid intermingling, contamination or (rl
deterioration that may affect the quality of the product. N
o
-o
B.4.4 Process control o
o
The quality manualshould include: 3
r
a description of equipment and installation; ss
a description of the flow of constituents and the processes canied out on them. lf appropriate this should s
incorporate a flow diagram;
g
J

a schedule for monitoring the performance of the process (manual or automatic systems), including a
o
@
record of equipment performance against the stated tolerances. b
so
N'
8.4.5 lnspection, calibration and control of process equipment o
N
N
The quality manual should identify items of measuring devices that require calibration and the frequency of
such calibration.

Calibration procedures should be provided, including the permitted tolerances for the devices to remain in
service. The quality manual should state the required accuracy of all calibrations.

The equipment should be adequately maintained to ensure that it continues to be capable of producing
mixture to the required specifications and tolerances.

8.4.6 Handling and delivery

The quality manual should contain procedures to ensure that the mixture is handled and, where appropriate,
delivered with the minimum of segregation or degradation and within the permitted water content range and
time limit.

25
EN 14227-1:2013 (E)

At the point of delivery, the mixture should be identifiable and traceable with regard to its production data. The
manufacturer should maintain records of relevant data of production, which can be referenced from
information when appropriate on the delivery ticket.

lf appropriate, the manufacturer's quality manual should describe the characteristics of any mixture storage
system and define its mode of operation. The manufacturer should ensure through checks, inspections and
records that such systems are used correctly and that mixtures maintain their suitability for use.

B.5 lnspection and testing of constituents and mixtures during production

B.5.1 General
At the start of the production process, the homogeneity of the mixture should be considered with regard to the
specification, the type and quality of the production plant and the quality and homogeneity of the constituents.
@
This can be appreciated either from past production experience or by undertaking specific tests.
@
The quality manual should specify the frequency and nature of regular tests/checks/inspections that should be
N
carried out during production. The manufacturer should prepare a schedule of frequencies considering: o
N
test frequencies in relation to periods of actual production of each mixture;
N
E
z
test frequency where automated surveillance and monitoring of the production process exists; o
statistical approach for testing
o
o
{
o,
Reasons for changing the test frequencies and analysis should be stated in the quality manual. o
o
o
(rl
NOTE lf appropriate, long-term experience of the consistency of a particular property, as well as mixtures with an (,l
established record for conformity, can be taken into account. N
o
-o
B.5.2 Characteristics that require control during production o
o
These may include: 3
f
properties of the constituents including water content (before production); 5
s
s
proportioning of the constituents including added water; q
=
o
grading of the fresh mixture; @
b
(o
water content of the fresh mixture.
iJ
o
l\)
The above characteristics should comply with the requirements of the target composition of the mixture l\)
(8.4.2).

B.5.3 Frequency of sampling the mixture

During the regular production of the mixture, the sample frequency may be as follows:

ln the case of plants with a validated and accepted automated surveillance and data collection system
giving computerised composition for every truck or every batch, one sample should be taken every
2 000 t or 1 000 m3 or one per day for lesser quantities.

ln the case of other types of plants or production, one sample should be taken every 300 t or 150 m3, with
a minimum of 1 sample per day.

26
 EN'14227-1:2013 (E)

Alternatively and independent of the type of mixing plant, the frequency of sampling can be on a time
related rather than a quantity related basis, such as a minimum of 1 sample per week or 1 sample per
day depending on the characteristic being measured.

ln the case of occasional production of a standard mixture, the production should be assessed cumulatively
with previous production with the same or similar criteria. The frequency of sampling can be adjusted on a
contract-by-contract basis according to the overall quantity of production required.

8.6 lnspection and testing equipment

8.6.1 Genera!
All necessary facilities, equipment and personnel should be available to carry out the required inspections and
tests.
@
Normally the testing should be performed according to the specified test methods given in the relevant a
standard.
N
o
N
Other test methods may be used, if correlations or safe relationships between the results of these test Ju
methods and the reference methods have been established.
o
z
8.6.2 Measuring and testing equipment o
The manufacturer should be responsible for the control, calibration and maintenance of his inspection, o
o
measuring and testing equipment. !
o)
o
o
8.6.3 Measuring and testang equipment in the process o
(rl
(,l
N
The points in the process where measuring equipment needs to be deployed should be stated in the quality o
manual. I
