The work of preparing International Standards is normally carried out through ISO technical
14、 committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with
15、 the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed f
16、or the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives). Attention is drawn to the possibility that some of the elements of this document may be the subject of patent r
17、ights. ISO shall not be held responsible for identifying any or all such patent rights. Details of any patent rights identified during the development of the document will be in the Introduction and/or on the ISO list of patent declarations received (see www .iso .org/ patents).

31、) 4.1.1 General requirements The body of the firework case shall be made of paper, cardboard, plastics or other non-metallic materials which do not produce hard or brittle fragments. The base (end closures) or means of fixing shall be made of non-metallic material. Where technically necessary, wood,
32、 staples, nails, aluminium coated foil or binding wires may be used. Conformity to this requirement shall be verified by visual examination. For articles fitted with a friction head, the primary pack shall be fitted with a striking surface for safety matches. Conformity to this requirement shall be
33、verified by visual examination. The striking surface shall be resistant enough to allow ignition of all the articles included within the primary pack when tested in accordance with ISO 25947-4:2017, 6.17. The striking surface on the pack shall be covered or the pack shall be sealed, verified by visu
34、al examination. 4.1.2 Specific r equir ements For bangers and flash bangers, cardboard wrapped in cord is permitted as construction material. Double flash bangers shall have a base plate.
