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 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". 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.

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 1 firework or a category 2 mini rocket, securely attach the 50 g mass with clamping device (5.6.1) to the initial fuse. If testing a category 2 firework other than a mini rocket or a category 3 firework, securely attach the 100 g mass with clamping device (5.6.2) to the initial fuse. 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).
