All characteristics covered by this standard shall be determined with tests performed by an independent third party (
Notified Test Body) under the responsibility of a
Notified Product Certification Body responsible for the interpretation and classification of the obtained test results.
Factory Production Control (FPC) After the successful testing and assessment of the product the Notified Product Certification Body inspects the manufacturing plant (Initial inspection) and assesses the Factory Production Control system (i.e. ISO or similar). The manufacturer is furthermore responsible for testing further samples taken directly from the manufacturing plant to keep and maintain his "Certificate of Constancy of Performance" valid and to be able to continue to CE mark his products.
Permitted wall types The EN standard introduces the concept of standard supporting constructions (essentially wall types). These are the constructions into which the test specimen is allowed to be built. The available standard supporting constructions are: • High density rigid construction: Blockwork, masonry or homogeneous concrete wall • Low density rigid construction: Aerated concrete block wall • Flexible construction: Lightweight plasterboard faced steel stud partition == See also ==
