5.8.1
Weigh the pyrotechnic composition not contained in pyrotechnic unit(s) using the accuracy of weighing respectively the balance according to Table 1. Record the mass. If applicable, remove the pyrotechnic composition from each pyrotechnic unit, separate bursting charge, report charge and effect charge and weigh each portion. Record the mass of each portion.
6.3 Angle of ascent, effect-, rising/bursting-, drop height 6.3.1 Apparatus Universal surveying instruments (USI) in accordance with 5.12. 6.3.2 Procedure
The articles shall be fired vertically (firing device at 90° ± 2°). The measurement of heights may be made according to one of the methods as described in Annex B.
For articles that project pyrotechnic units beyond 30 m or contain pyrotechnic units that are self propelling, two measuring positions are required. For all other cases one measuring point is adequate. If two measuring points are necessary, vertical and horizontal angles shall be recorded. In case of one measuring point, at least the vertical angle shall be recorded. In order to achieve a reasonable accuracy, the distance between firing point and measurement location, referred to as base length here, has to be adjusted to the measurement device. The vertical angle should be within the range of 30° to 60° (optimal 45°). If the monitoring position(s) is / are not in the same horizontal plane as the article, appropriate corrections shall be made in the calculation of heights. Generally the measuring distance should be adapted to the article (height of ascent expected).
When using two positions for monitoring the height of ascent and angle of flight, they shall be positioned at a measured distance and at an angle of 90º to each other in relation to the article or a sufficient angle to assure a good validity of the measurement (depending on the method of measurement and calculation of the heights). 6.4 Measurement of sound pressure level SIST EN 16256-5:2013



EN 16256-5:2012 (E) 12 6.4.1 Apparatus  Sound level meter (5.13);  Measuring tape (5.5). 6.4.2 Procedure For articles where the distance at which the maximum A-weighted impulse sound pressure level is calculated to be 120 dB (AI) is less than half of the largest distance calculated from the other effect parameters based on type test measurements, the sound pressure level may be omitted from the batch test. In this case, the sound reflecting surface of the test area is not required. Set up the microphone of the sound level meter in the test area (4.3) at a distance of 8 m and at a height of 1,0 m. For articles with an effect height greater than 50 m set up the microphone at a distance that allows accurate measurement of the sound level and measure the distance to firing point with measuring tape (5.5). The sound level meter shall be oriented to the firing point. For line rockets set up the microphone of the sound level meter in the test area (4,3) at a distance of 8 m from the line, perpendicular to the direction of travel and at 50 % of the functioning length. Record the maximum A-weighted impulse sound pressure levels as measured by the sound level meter (5.13). The minimum safety distance depending on the sound pressure level can be calculated in accordance with Annex C.
6.5 Timing measurement 6.5.1 Apparatus  Timing device (5.2.1);  Ignition source (5.17). 6.5.2 Procedure 6.5.2.1 Ignition time Electric igniters may be fitted to the pyrotechnic article or supplied separately. If the igniter is supplied separately, insert it into the test article and ignite as indicated in the instructions for use. The igniter shall ignite the preliminary or main effect directly and without delay. The correct functioning of the electrical igniter shall be verified by visual or aural examination of the ignition in accordance with 6.11. 6.5.2.2 Non-electric ignition Remove any protection from the initial fuse and ignite in accordance with the instructions for use. Apply the ignition source (5.17) to the initial fuse and at the same instant, start the timing device (5.2.1). Stop the intermediate time at the moment the initial fuse ignites. If the initial fuse fails to ignite within the required time, record the fact and do not proceed with further testing of those articles. If the article has a friction head, strike it on the ignition source supplied with the article. If the article fails to ignite at the first strike, try it twice more. Record whether the article ignited or not. 6.5.2.3 Initial fuse time Initial fuse time shall be measured by using the timing device (5.2.1) and shall be recording from the moment the initial fuse ignites to the time the articles starts to produce its preliminary effect.

6.8 Burning rate of composition 6.8.1 Apparatus  timing device (5.2.1);  mould device (5.20). 6.8.2 Procedure Calculate the burning rate by using the timing device (5.2.1) Measure the burning time of the tested article and divide the net explosive content (in grams) or the corresponding length (in centimetres) by the measured time (in seconds). Record the burning rate.
For loose compositions, the procedure should be performed in accordance with 33.2.1.4.3 of the “Recommendations on the Transport of Dangerous Goods – Manual of Tests and Criteria” (see [1]), using the mould device (5.20) and the timing device (5.2.1). An equivalent method may be used. 6.9 Projected Debris
