The base (end closures) or means of fixing shall be made of non-metallic material. Where technically necessary, wood, 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 verified by visual examination.
4.1.2? Specific? requirements — For bangers and flash bangers, cardboard wrapped in cord is permitted as construction material. — Double flash bangers shall have a base plate. — For double flash bangers, the inside diameter of the tube shall not exceed 30 mm. Conformity to this requirement shall be verified by the method described in ISO 25947-4:2017, 6.2.5. — For batteries and batteries requiring external support the tubes of mines, Roman candles or shot tubes shall have a maximum angle of 30° to the vertical, when tested in accordance with ISO 25947-4:2017, 6.19. For combinations and combinations requiring external support, this requirement applies to the tubes of mines, Roman candles and shot tubes.
