Conformity to this requirement shall be verified by visual examination. 4.2 Attachment of initial fuse The attachment of the protruding fuse to the Roman candle 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.

When tested in accordance with 8.3, a category 2 Roman candle shall produce a maximum A-weighted impulse sound pressure level (LAImax) of not higher than 120 dB(AI) at a horizontal distance of 8,0 m from the testing point and at a height of 1,0 m above the ground. When tested in accordance with 8.3, a category 3 Roman candle shall produce a maximum A-weighted impulse sound pressure level (LAImax) of not higher than 120 dB(AI) at a horizontal distance of 15,0 m from the testing point and at a height of 1,0 m above the ground. 5.6 Height of explosions and bursting (if applicable) When tested in accordance with 8.3, the pyrotechnic units of a category 2 Roman candle shall not explode or burst below a height of 8 m. When tested in accordance with 8.3, the pyrotechnic units of a category 3 Roman candle shall not explode or burst below a height of 20 m.

1) If applicable.
— 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 Roman candle at least the abbreviations allowing the identification of — the manufacturer; or — the distributor or importer, with an additional code or abbreviation for the manufacturer shall be marked. 7.5 Reference to this standard A Roman candle shall be marked with ‘EN 14035-28'. A primary pack shall be marked with the words 'Contents conform to EN 14035-28'.

8.2 Vertical stability test (type test) 8.2.1 Apparatus 8.2.1.1 Wooden block, rectangular, with an upper surface inclined at 10° to the horizontal. 8.2.1.2 Timing device, capable of being read to the nearest 0,1 s. 8.2.2 Procedure 8.2.2.1 Place the base of the Roman candle on the inclined surface of the wooden block (8.2.1.1). For polygonal (triangular, etc.) bases, align one edge of the base with the top edge of the wooden block. 8.2.2.2 Using the timing device (8.2.1.2), observe and record whether the Roman candle falls over within 5 s. If it falls over discontinue the test. 8.2.2.3 Rotate the Roman candle clockwise through 90° and repeat the observation described in 8.2.2.2. 8.2.2.4 Repeat the operations described in 8.2.2.3 twice more (unless the Roman candle falls over). 8.3 Performance (type test and batch test) 8.3.1 Test environment 8.3.1.1 Test area for category 2 Roman candles. The test area shall be an outdoor site, on level ground, with a radius of at least 9 m and a smooth, hard, horizontal, sound-reflecting, non-flammable surface (for example, concrete). If applicable, provision shall be made at the centre of the test area for partially burying the Roman candle to be tested. A circle, radius 6,0 m, shall be marked around the centre of the test area. One position for monitoring the height of explosion or bursting of the pyrotechnic units shall be provided, at a measured distance of at least 8 m from the testing point (in the centre of the test area).

8.3.2.5 Measuring device, capable of measuring a height of 1,0 m to the nearest 10 mm. 8.3.3 Procedure 8.3.3.1 Measure and record the wind speed (see 8.3.1.3). 8.3.3.2 If carrying out a type test of Roman candles, set up the microphone of the sound level meter (8.3.2.3) in the test area (8.3.1.1 or 8.3.1.2), at a height of 1,0 m above the ground, determined by the measuring device (8.3.2.5), and at a horizontal distance from the testing point of 8,0 m for category 2 Roman candles or 15,0 m for category 3 Roman candles. Direct the microphone horizontally towards the testing point and, if necessary, connect it to the sound level meter. 8.3.3.3 Position the Roman candle, 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). Stop the intermediate time at the moment the protruding fuse ignites. If the initial fuse fails to ignite within 10 s, record the fact and do not proceed with further testing of that Roman candle. Otherwise, stop the timing device when the Roman candle starts to produce its first effect. Record whether the initial fuse ignited within 10 s and whether the ignition of the initial fuse was visible.
