CIVIL AVIATION DEPARTMENTHONG KONG, CHINAAirworthiness Notice1 IntroductionTHIS NOTICE GIVES DETAILS OF A MANDATORY ACTIONFLAME RESISTANT FURNISHING MATERIALSNo. 58Issue 530 September 20061.1 Materials used for aircraft cabin furnishings are required to have flameresistant properties.1.2 Materials used when carrying out repairs or modifications to an aircraft cabinfurnishings are also required to have flame resistant properties, which areeither at least equal to those of the materials used in the original design asaccepted for Hong Kong certification, or in compliance with the current orHong Kong equivalent requirements.2 Requirements for Initial Acceptance of MaterialsWherever possible only inherently flame resistant materials shall be used. However,materials which meet the requirements by the use of a flame retardant process,applied either during or after manufacture, may also be used provided that (since allmaterials may at some time be dry-cleaned or washed) the material is shown to beflame resistant when tested both before and after being subjected to threerepresentative cleaning processes.3 Requirements for Maintenance of Flame Resistance3.1 Continuance of the flame resistance properties of furnishing materials maydepend upon their use in service and the methods used in their cleaning.Experience has shown that:(a)(b)The proprietary flame retardant processes often applied to furnishingmaterials during or after manufacture, in order to provide the necessaryflame resistant properties, may be destroyed or seriously impairedwhere incorrect dry cleaning, laundering or proprietary finishingprocesses which enhance durability and minimise soiling, are used.The application of one flame retardant process on top of another of adifferent type, may have the effect of inhibiting the properties of bothprocesses.AN-58 P.130 September 2006
