    26、ioned appropriately for the type of measurement being carried out. For aquatic fireworks, a water test area shall be available for testing the resistance to moisture and functioning in the expected manner. 4.2 Wind measurement The wind speed at a height of 1,50 m above the ground shall be measured a

    27、nd recorded using a wind speed meter (see 5.5). No performance testing shall be carried out if the wind speed exceeds 5,0 m/s. 5 Apparatus Any equivalent apparatus with the same accuracy or better may be used. 5.1 Timing device.

    30、us. The apparatus shall provide a deceleration of 490 m/s2(-50/+100) m/s2(when measured at the centre of an unloaded platform) and the shock impulse duration (time elapsed from the starting of the machines deceleration to the time in which the deceleration reaches its maximum value during each first

    31、 shock pulse) shall be 2 ms 1 ms working at a frequency of 1 Hz 0,1 Hz. An example of an apparatus is shown in Annex A. 5.10 Devices for measuring heights. Heights shall be measured using universal surveying instruments (USI) such as theodolites, electronic spirit levels or video (visible and/or inf

    32、rared) systems. Examples of measuring methods and the calculation of the height are given in Annex B. 5.11 Goniometer. Goniometer reading to 1 or better. 5.12 Mortar. The rising height of shells depends particularly on the clearance of the shell in the mortar (ratio of the maximum cross section area

    33、 of the shell (AShell) to the inner cross section area of the mortar (Amortar), also designated as “Q“. Q is the ratio of the outer diameter of the shell (do,shell,including the fuse to the lifting charge) squared over the inner diameter of the mortar (di,mortar) squared. The outer diameter of the s

    34、hell shall be measured horizontally at the place of largest diameter including the fuse to the lifting charge. The following conditions shall be achieved: 98,09,0mortari,2shello,2mortarshell=ddAAQ BS EN 16261-3:2012EN 16261-3:2012 (E) 7 shello,2mortari,shello,21,102,1 ddd For calibre 100 mm, a wider

    35、 tolerance can be accepted. The following conditions shall be achieved: 98,083,0*100Q shello,2mortari,*shello,22,1(02,1 ddd Another determining factor influencing the rising height is the length of the mortar (lmortar) length from the mortar muzzle to the mortar ground. The dimensions of the mortar

    36、may also be determined from Figures 1, 2 and 3.

    46、icrophone of the sound level meter in the test area (Clause 4) at a height of 1,0 m. The sound level meter shall be orientated to the firing point. The distance between the measuring and firing point may be the same as for the measuring of the Rising Height according to 6.4. Place and ignite the tes

    47、t sample in accordance with the labelled instructions and instructions for use, and record the maximum A-weighted impulse sound pressure levels as measured by the sound level meter (see 5.8) and the distance from the firing point (see 5.4). NOTE An example of the calculation method for safety/protec

    48、tion distance is given in Annex C. 6.6 Extinguishing of flames 6.6.1 Apparatus Timing device (see 5.1). 6.6.2 Procedure At the moment the tested article ceases to function (see 6.10.2), immediately start the timing device (see 5.1) and record the time until all flames caused by the functioning of th
