Annex A (informative) Factory production control (FPC)
A.1 General A.1.1 Objects The manufacturer shall exercise a permanent FPC (e.g. a quality management system based on the relevant part of the EN ISO 9000 series, or otherwise). The manufacturer is responsible for organising the effective implementation of the FPC system. Tasks and responsibilities in the production control organisation should be documented and this documentation should be kept up-to-date. In each factory the manufacturer may delegate the action to a person having the necessary authority to: a) identify procedures to demonstrate conformity of the construction product at appropriate stages; b) identify and record any instance of non-conformity; c) identify procedures to correct instances of non-conformity.
A.1.2 Documentation The manufacturer shall draw up and keep up-to-date documents defining the FPC which he applies. The manufacturer's documentation and procedures shall be appropriate to the construction product and manufacturing process. All FPC systems shall achieve an appropriate level of confidence in the conformity of the construction product. This involves: a) the preparation of documented procedures and instructions relating to FPC operations, in accordance with the requirements of this European Standard (see D.1.3): b) the effective implementation of these procedures and instructions; c) the recording of these operations and their results; d) the use of these results to correct any deviations, repair the effects of such deviations, treat any resulting instances of non-conformity and, if necessary, revise the FPC to rectify the cause of non-conformity.
A.1.3 Operations FPC includes the following operations: a) the specification and verification of raw materials and constituents; b) the controls and tests to be carried out during manufacture of the construction product according to a frequency laid down; c) the verifications and tests to be carried out on finished construction products according to a frequency which may be laid down in the technical specifications and adapted to the product and its conditions of manufacture. NOTE The operations under b) centre as much on the intermediate states of the construction product as on manufacturing machines and their adjustment and equipment etc. These controls and tests and their frequency are chosen based on type of construction product and composition the manufacturing process and its complexity, the sensitivity of product features to variations in manufacturing parameters etc.

prEN 1337-8:2002 (E)
With regard to operations under c), where there is no control of finished construction products at the time they are placed on the market, the manufacturer shall ensure that packaging, and reasonable conditions of handing and storage, do not damage construction products and that the construction product remains in conformity with the technical specifications. The appropriate calibrations must be carried out on defined measuring and test instruments.
A.2 Verifications and tests A.2.1 General comments The manufacturer shall have or have available the installations, equipment and personnel which enable him to carry out the necessary verifications and tests. He may, as may his agent, meet this requirement by concluding a sub-contracting agreement with one or more organisations or persons having the necessary skills and equipment. The manufacturer shall calibrate or verify and maintain the control, measuring or test equipment in good operating condition, whether or not it belongs to him, with a view to demonstrating conformity of the construction product with its technical specification. The equipment shall be used in conformity with the specification or the test reference system to which the specification refers.
A.2.2 Monitoring of conformity If necessary, monitoring is carried out of the conformity of intermediate states of the product and at the main stages of its dispatch. This monitoring of conformity focuses where necessary on the construction product throughout the process of manufacture, so that only products having passed the scheduled intermediate controls and tests are dispatched.
A.2.3 Tests Tests shall be in accordance with the test plan (tables 2 and 3) and can be carried out in accordance with the methods indicated in this European Standard. NOTE Initial type tests on the product may not be carried out by the manufacturer himself but shall be carried out or validated by an approved body.
The manufacturer shall establish and maintain records which provide evidence that the construction products has been tested. These records shall show clearly whether the construction product has satisfied the defined acceptance criteria. Where the construction products fails to satisfy the acceptance measures, the provisions for non-conforming products shall be applied.
A.2.4 Treatment of construction products which do not conform If control or test results show that the construction product does not meet the requirements, then necessary corrective action shall immediately be taken. Construction products or batches not conforming shall be isolated and properly identified. Once the fault has been corrected, the test or verification in question shall be repeated. If construction products have been delivered before the results are available, a procedure and record shall be maintained for notifying customers.
A.2.5 Recording of verifications and tests (manufacturer's register) The results of factory production controls shall be properly recorded in the manufacturer's register. The construction product description, date of manufacture, test method adopted, test results and acceptance criteria shall be entered in the register under the signature of the person responsible for control who carried out the verification.
