This European Standard gives the procedures for preparing reports on the extended application process using the results of reaction to fire tests, fire resistance tests or external fire exposure to roof tests undertaken for fire classification of products and product families in accordance with the various parts of EN 13501. This standard makes reference to `extended application standards' throughout, wherever this term is used it refers to either a standard prepared by CEN/TC127 `Fire safety in buildings' or the relevant product standard which includes information on extended application. In some cases, where a standard is not yet published, a relevant EC Group of Notified Bodies (GNB) Fire Sector Group (FSG) Recommendation is available for use by Notified Bodies in attestation procedures for CE marking under the Construction Products Directive (CPD), http://ec.europa.eu/enterprise/newapproach/nando/ . The European system currently permits extended application rules to be included in technical specifications. Committees producing these rules are asked to seek the guidance of CEN/TC127 to ensure that their rules comply with standards prepared by CEN/TC127. In cases where extended application rules in technical specifications do not comply with standards prepared by CEN/TC127 the CEN BT shall be informed.
