PREFACE This Standard was prepared by the Standards Australia Committee on Fire Tests on Building Materials, Components and Structures. It is based on BS 8202: Coatings for fir e protecti prote cti on of build ing el ement s, Part 1: Code Code of practice practice for the selection and installation of sprayed mineral coatings. The technical technical content content of the two S tandards tandards is identical identical and t he only differenc differences es are that, that, where where possi possible ble,, referen references ces to other other British British Standa Standards rds have have been been replac replaced ed by references to the equivalent Australian Standards.

For many applicati applications ons particularly particularly those relating to building control, it will be necessary for the specifier, manufacturer or applicator to produce test reports from a registered testing authority to show that the required performance criteria can be achieved. Any changes in the spray system, i.e. primer, spray and surface finish, or its method of application may affect its performance. Ideally, performance tests previously carried out should be repeated to ensure that the level of performance is not affected. However, in practice this is not always possible because of the cost of some types of test, particularly fire-resistance tests complying with AS 1530.4, and because of the range of variables which may occur, e.g. raw materials may be obtained from several sources or a spray may be required required to be used with a large number of different different primers. Thus changes changes in the chemical chemical or physical nature nature of the compon component entss of the spray or their their relati relative ve propor proportio tions ns should should be the subject subject of a full full re-tes re-testt in accordance accordance with the appropriate appropriate performance Standar Standard d whilst whilst detail changes changes in the spray system system may be validated validated without without repeating repeating the appropriate appropriate performance performance test, test, using analytical analytical laboratory laboratory tests or reduced scale performance tests. It is important that any reduced scale tests can be shown to correlate with the appropriate performance performance Standard. Standard. In many cases the spray manufact manufacturer/s urer/supplie upplierr would be the only source source of this information. information. The justification justification for any assessmen assessmentt of changes changes in the spray spray system system should should be available available for inspection as appropriate.
