Any equivalent method with the same sensitivity and the same accuracy or better can be used. 6.1 Construction and stability 6.1.1 Length of handle 6.1.1.1 Apparatus — Calliper (5.2); — ruler (5.3); — frame (5.20). 6.1.1.2 Procedure 6.1.1.2.1 Fireworks with visible handles For type test measure and record the length of the uncoated end using the calliper (5.2) if the length of the handle is smaller than or equal to 100 mm or using the ruler (5.3) if the length exceeds 100 mm. For batch test measure the length of the uncoated end by using the calliper (5.2), the ruler (5.3) or the frame (5.20) to determine the length of the uncoated end and record if the length of uncoated end is within the requirements. If using the frame (5.20), place the fireworks with the handles in accordance with Figure 3 and record whether and if so, for how many items, the uncoated end is less than the required length. 6.1.1.2.2 Hand-held fountains without a separate handle Carry out the type test using the fireworks that are used for determination of the net explosive content. Cut open the marked end of the firework case. Using calliper (5.2), measure and record the length of the firework case which is not filled with pyrotechnic composition to the nearest 1,0 mm. 6.1.2 Attachment of separate handle 6.1.2.1 Apparatus — Timing device (5.1.1); — weight (5.6.3). 6.1.2.2 Procedure Clamp the sample by means of a clamping device in a position such that the handle of the sample is pointing vertically downwards. Securely attach the 500 g weight (5.6.3) to the handle. Using the timing device (5.1.1) determine and record the time until the handle of the sample becomes detached. If this time is longer than 10 s, stop the test and record as “longer than 10 s”. SIST EN 15947-4:2016

EN 15947-4:2015 (E) 13 6.1.3 Length of item 6.1.3.1 Apparatus — Ruler (5.3). 6.1.3.2 Procedure Use the ruler to measure and record the total length of the test item to the nearest 1 mm. 6.1.4 Length of pull-string or pull-strip 6.1.4.1 Apparatus — Ruler (5.3). 6.1.4.2 Procedure Carefully extend the pull-string or pull-strip to its full length without firing the test item. Using the ruler (5.3), measure the total exposed length of the pull-string or pull-strip. Record the length. 6.1.5 Determination of diameter 6.1.5.1 Apparatus — Calliper (5.2). 6.1.5.2 Procedure Using the calliper (5.2), measure the inside diameter of the tube at least three times at different positions to the nearest 1,0 mm. Using the calliper (5.2), measure the outer diameter of the propellant tube of the mini rocket at least three times at different positions to the nearest 0,5 mm. Record the individual diameters and calculate the mean diameter. 6.1.6 Attachment of initial fuse 6.1.6.1 Apparatus — 50 g mass with clamping device (5.6.1); — 100 g mass with clamping device (5.6.2); — timing device (5.1.1); — clamping device (5.11). 6.1.6.2 Procedure Clamp the firework by means of a clamping device (5.11) in such a position that the initial fuse is pointing vertically downwards. If testing a category F1 firework or a category F2 mini rocket, securely attach the 50 g mass with clamping device (5.6.1) to the initial fuse. If testing a category F2 firework other than a mini rocket or a category F3 firework, securely attach the 100 g mass with clamping device (5.6.2) to the initial fuse. SIST EN 15947-4:2016

EN 15947-4:2015 (E) 14 Using the timing device (5.1.1), determine and record the time until the initial fuse becomes detached. If this time is longer than 10 s stop the test and record as “longer than 10 s”. 6.1.7 Attachment of sealing paper, ignition head or friction head See mechanical conditioning (6.14). 6.1.8 Resistance to ignition by an abrasive surface 6.1.8.1 Apparatus — Abrasive sheet (5.8). 6.1.8.2 Procedure Strike the friction head of the test sample in the test area (4.2 or 4.3) on the rough surface of the abrasive sheet (5.8). Record whether the friction head ignites. 6.1.9 Height of initial fuse for mounted wheels in category F3 6.1.9.1 Apparatus — Measuring tape (5.4). 6.1.9.2 Procedure Mount the wheel in accordance with the instructions on the label. Extend the protruding fuse vertically downwards and
