Conformity to this requirement shall be verified by visual examination. 4.2 Attachment of initial fuse The attachment of the protruding fuse to the shot tube shall be secure when tested in accordance with 8.1. 4.3 Protection of initial fuse 4.3.1 General The initial fuse shall be protected in one of the ways specified in 4.3.2, 4.3.3 or 4.3.4. 4.3.2 Initial fuse protected by fuse cover An orange fuse cover shall be in place over the initial fuse. Conformity to this requirement shall be verified by visual examination. 4.3.3 Initial fuse protected by primary pack or selection pack The shot tube shall be contained in a primary pack or selection pack conforming to Clause 6. Conformity to this requirement shall be verified by visual examination. 4.3.4 Protruding fuse designed to resist side ignition When tested in accordance with 8.6, the protruding fuse shall not ignite.

1) If applicable.
7.4 Name, address and telephone number of manufacturer or distributor or importer Labelling shall include: — name or trade mark, the address and the telephone number of the manufacturer; or — an abbreviation or a code allowing the identification of the manufacturer, and the name or trade mark, the address and the telephone number: — of his authorized distributor; or — if the manufacturer is not established in a CEN member country, of the importer in a CEN member country. The address shall comprise at least the town and the country. On the shot tube at least the abbreviations allowing the identification of — the manufacturer; or — the distributor or importer. An additional code or abbreviation for the manufacturer shall be marked. 7.5 Reference to this European Standard A shot tube shall be marked with ‘EN 14035-38'. A primary pack shall be marked with the words 'Contents conform to EN 14035-38'. 7.6 Printing 7.6.1 Labelling Labelling shall be clearly visible, easily legible, indelible and on a single-colour background. NOTE Printing errors which are not misleading should not be classified as faults. 7.6.2 Type size When measured in accordance with 8.7, the type sizes shall be such that the height of the capital letter “X” (in upper case) is at least 2,8 mm for the information specified in 7.2, 7.3 and 7.8 and at least 2,1 mm for the other information. 7.7 Marking of very small shot tubes 7.7.1 Reduced size If the shot tube does not provide enough space for the specified information using the types sizes specified in 7.6.2, for the information specified in 7.2 and 7.3 the type size shall be reduced to 2,1 mm. 7.7.2 Reduced information If the shot tube does not provide enough space to carry all the specified information even in reduced type size, at least the information specified in 7.4 shall be given on the shot tube, if at all possible.

Where y is the distance, in m, from the viewing point to the testing point (see Figure 2). The observer is positioned so that the bottom edge of the triangle on the front screen coincides with the top of the shot tube and the bottom edge of the tape on the back screen coincides with the bottom edge of the horizontal tape on the front screen.

Direct the microphone horizontally towards the testing point and, if necessary, connect it to the sound level meter. 8.3.3.3 Position the shot tube, in accordance with the instructions on the label, in the centre of the test area. Remove the orange fuse cover, if any, and straighten the initial fuse, if necessary. Apply the ignition source (8.3.2.2) and, at the same instant, start the timing device (8.3.2.1). Observe the intermediate time at the moment the initial fuse ignites. If the initial fuse fails to ignite within 10 s, record the fact and do not proceed with further testing of that shot tube. Otherwise, stop the timing device when the shot tube starts to produce its principal effects. Record whether the initial fuse ignited within 10 s and whether the ignition of the initial fuse was visible. 8.3.3.4 Record the duration of the initial fuse burning. Observe and record whether the pyrotechnic unit is ejected and whether it functions. After the shot tube has ceased to function start the timing device (8.3.2.1) immediately and record whether any flames caused by the functioning of the shot tube are extinguished within 60,0 s after the shot tube has ceased to function.

6,0 m, for a category 2 shot tube, or 15,0 m, for a category 3 shot tube, from the testing point. Observe and record whether the shot tube remains upright whilst functioning. 8.3.3.5 Record the maximum A-weighted impulse sound pressure level, as measured by the sound level meter (8.3.2.3). 8.3.3.6 After the shot tube has ceased to function examine the firework case and record whether it has any additional holes or splits. 8.4 Determination of internal diameter (type test) 8.4.1 Apparatus Vernier callipers, reading to 0,1 mm, complying with ISO 3599. 8.4.2 Procedure Using the callipers (8.4.1), measure the inside diameter of the shot tube to the nearest 1 mm. Record the diameter. 8.5 Determination of net explosive content (type test) 8.5.1 Apparatus Laboratory balance
