4.2.1.2 Provisions for processing plants
In production plants for the controlled processing of silica fume, for example by selection, drying, blending,
densifying or slurrifying of silica fume, the relevant information on each consignment of incoming silica fume and all
operating steps in the process shall be documented in the works´ quality manual by the manufacturer in agreement
with the certification body. The following data shall be at least part of this documentation:
a) manufacturer and the production location from which the silica fume originates;
b) acknowledgement that the silica fume is according to 3.24;
c) in case of blending only, the properties of each incoming silica fume shall be controlled on a regular basis in
order to be able to achieve the target properties of the silica fume blend. On each incoming silica fume the
relevant properties listed in Table 1 of EN 13263-1:2005, except activity index, should be tested by the supplier
of the incoming silica fume. The minimum testing frequency should be chosen as indicated in Table 1 of
EN 13263-1:2005, "Routine situation", and should be documented in the works´ quality manual. When
blending silica fumes from production plants at different locations, each incoming silica fume shall conform to
the requirements for silicon dioxide content and specific surface according to EN 13263-1:2005, 5.2.1 and
5.3.1;

the procedures and frequencies laid down in the works´ quality manual.
4.2.2.2 Inspection and test status
Procedures for the inspection and test status through the stages of manufacture shall be detailed in the works´
quality manual. These shall include procedures for the control of off-specification intermediate materials.
To ensure that only silica fume conforming to EN 13263-1 is conveyed to the silo, samples shall be taken from
appropriate places prior to the silo for certified silica fume in agreement with the certification body. The sampling
places shall be laid down in the works´ quality manual. Spot samples shall be taken for the determination of
specific surface and loss on ignition in agreement with the certification body.
4.2.3 Handling, storage, packaging and delivery
The works´ quality manual shall describe the precautions taken for the protection of the quality of the silica fume
while under the responsibility of the manufacturer. It shall include a description of the procedures used at depots.

4.3 Autocontrol testing of samples
4.3.1 Sampling and testing
The manufacturer shall operate a system of autocontrol testing for the certified silica fume. This system shall be
used to demonstrate conformity to the requirements in clause 7 of EN 13263-1:2005. The properties to be tested,
the testing methods, the minimum frequency of autocontrol testing and the conformity criteria shall be in
accordance with the basic requirements given in clause 7 of EN 13263-1:2005. For silica fumes not being

All test data shall be documented.
4.3.2 Corrective action
The works´ quality manual shall document procedures for the review and adjustment of the production control in
case of non-conformity (see 6.1).
The actions taken in the event of non-conformity shall be recorded in a report subject to inspection during the
management review.
In the event of silica fume yielding a test result not conforming to the single result limit value conformity criteria
specified in EN 13263-1, the manufacturer shall immediately determine the affected quantity, take appropriate
action to prevent the dispatch of this quantity and inform the affected customer if such silica fume has been
released. In addition, the manufacturer shall immediately determine the causes of such non-conformity, take
corrective actions and undertake a review of all relevant production control procedures. All such actions and
findings shall be appropriately recorded in a report subject to inspection during the management review.
NOTE The certification body may require to be kept informed of these actions and findings.
4.3.3 Measuring and test equipment for autocontrol testing
The equipment used for autocontrol testing shall be regularly checked and calibrated in accordance with
procedures and frequencies laid down in the works´ quality manual.
The works´ quality manual shall document procedures to ensure that all personnel involved in autocontrol testing
have appropriate experience and training. Appropriate records shall be retained.
4.3.4 Quality records
The manufacturer shall retain records of the autocontrol test results and appropriate records on test equipment for
at least the period required to comply with relevant legislation.
4.4 Further testing of samples
Once in a two-years period the properties listed in EN 13263-1:2005 Table 1 shall be further tested. The results of
this further testing shall not be used for the evaluation of conformity according to EN 13263-1:2005, 7.2.
NOTE The manufacturer may use this further testing for control of his testing procedures by using other personnel or other
equipment or in other ways let the testing deviate from the testing according to 7.1.1, but still be within the requirements of the
standard for the test method. If other methods than the reference methods are used for the autocontrol testing (see
EN 13263-1:2005 5.1), the further testing may be used to check the continued equivalence of the test methods.
