CEQMAS provides consultancy to Companies
setting up a Factory Production Control (FPC).
The purpose of factory production control is defined
in the Construction Products Directive as "the permanent internal control of production exercised by the manufacturer".
Factory production control therefore brings together
operational techniques and all measures allowing maintenance and control of the
conformity of the product with technical specifications. Its implementation may
be achieved by controls and tests on measuring equipment, raw materials and
constituents, processes, machines and manufacturing equipment and finished
products, including material properties in products, and by making use of the
results thus obtained.
The manufacturer is responsible for organising the
effective implementation of the factory production control system. Tasks and
responsibilities in the production control organisation should be documented
and this documentation should be kept up-to-date.
Production control operations include some or all of
the following operations:
- the specification and verification of raw materials
- the controls and tests to be carried out during
manufacture according to a frequency laid down;
- the verifications and tests to be carried out on
finished products according to a frequency which may be laid down in the
technical specifications and adapted to the product and its conditions of
This monitoring of conformity focuses where necessary
on the product throughout the process of manufacture, so that only products
having passed the scheduled intermediate controls and tests are dispatched.
Tests should be in accordance with the test plan and
be carried out in accordance with the methods indicated in the technical
specification. These methods should generally be direct methods. It is however
possible, in the case of certain characteristics, that the prescribed
specification gives the possibility of using indirect test methods if a
definite correlation or relationship can be established between a specified
characteristic and another characteristic which is easier or safer to measure.
If control or test results show that the product does
not meet the requirements, for example if the statistical variation of test
results exceeds the limits allowed by the technical specification, the necessary
corrective action must immediately be taken. If products have been delivered
before the results are available, a procedure and record should be maintained
for notifying customers.
All the Manufacturers having an FPC system which complies with EN ISO 9000
and which addresses the requirements of the appropriate harmonised standard are
recognised as satisfying the FPC requirements of the Directive.
