For aquatic fireworks, a water test area shall be available for testing the resistance to moisture and functionin
30、g in the expected manner. 4.2 Wind measurement The wind speed at a height of 1,50 m above the ground shall be measured and 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 ac

Sound level meter of class 1 conform to EN 61672-1 with a free-field microphone. 5.9 Shock apparatus. The ap
34、paratus 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 shock pul
35、se) 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 infrared) sys
36、tems. 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 of the sh
37、ell (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 shell shall
38、 be measured horizontally at the place of largest diameter including the fuse to the lifting charge.
